AutoCAD Tutorial for Electronics Engineering

from this tutorial we will start new series for electronics engineers in this tutorial we will create alarm circuit for drinking water click here scroll down and click on acadiso.dwt I will show you what is my unit setting for units type UN enter then length type is decimal precision is four digits then angle type is decimal degrees and precision is 0 then insertion scale millimeter so I will be keeping all the default setting as it is click on OK then my grids are on then object snap tracking is on then object snap is on click on this arrow I have selected endpoint midpoint center quadrant intersection and extension object snaps so these are my settings at first we will create this circle and this line click on circle click centre point take your cursor away and click we will be creating freehand circuits we are not using any dimensions click on line click on this quadrant point for straight line click on ortho mode once it becomes blue that means it is on when ortho mode is on your line will come straight then specify second point I will click here enter then I will copy this circle click on copy select this circle enter then specify base point for base point I will choose this quadrant then second point will be this end point and we will place one more here enter then we will need one line here for that click on line then to catch point here you will have to use nearest object snap for selecting nearest object snap press shift then right click and from this list you can select nearest click on nearest then click here nearest object snaps select the points wherever we clicks so I will click here then for inclined line make ortho off then take your cursor on this side and click and press Enter and zoom - then next is this line to shift this UCS icon type UCSicon enter then click on noorigin then click on line then click on this quadrant point make ortho on then take cursor on this side and click and enter then we will create this rectangle click on rectangle then specify first point take your cursor below and click the next is to create these two lines click on line click on this endpoint take your cursor below now it is showing a endpoint object snap we don't want endpoint object snap we want to create it straight so what you can do you can take your cursor to this endpoint don't click there and take it away so it will track that point click there now our line is straight click enter we can mirror this line here so it will come exactly opposite on this side click on mirror select this line enter then specify first point of mirror line so our mirror line will be in the center therefore we will take this mid point click there take your cursor below ensure that your line is straight and click and press Enter so here these two lines are created then we will create this horizontal line and vertical line again click on line then take your cursor to this endpoint take it below click take your cursor on this side we will create this line in line with this switch click here take it below and click enter then next is this line press enter you can press ENTER to repeat the last command press Enter then take your cursor to this endpoint take your cursor on this side click take it below then zoom it now here we want to create a resister make ortho off take your cursor on this side click click on this side and click and one more on this side you can track this endpoint and click and enter then we will copy this click on copy select these two lines and then base point will be this endpoint and second point will be these end points click on it enter now this has become larger we will have to make it smaller we can make it smaller using scale, click on scale select this object you can use window selection for window selection you have to click on left side in empty space and take your cursor on the right side all the complete objects inside this blue window will be selected click there then enter then base point will be this end point then we will give scale factor to reduce the size of the object you will have to give scale factor less than one so here I will specify scale factor of 0.8 enter now it is still looking larger we will further reduce the scale click on scale select this object enter specify this point we will make it 0.7 enter ok then we will need one more line here what we will do we will extend this line up to this line click on extend click on this arrow click on extend then this line will be our boundary line select it enter then click on this line press ENTER then zoom it then trim the unwanted objects for trim you can type TR enter then specify boundary edges for trim so I want to trim after this line and up to this line and I want to trim this line with reference to this line press ENTER click on the objects to be removed and press Enter zoom - so this is also ready then next is this side we will create this line then we will create this capacitor click on line take your cursor to this endpoint take it below click take it on the right side make ortho on and click and press ENTER press ENTER to repeat the line command take your cursor to this endpoint take it above click then take it below and click and enter then we need one arc here for that click on 3-point arc then take your cursor to this endpoint take your cursor on this side click and make Ortho Off take your cursor to this endpoint take your cursor on this side and click then again take your cursor to this end point and click now it is looking smaller we can increase the size using scale command click on scale select this object enter then base point will be this mid point then give the scale of 1.3 to increase the size of the object you will have to give scale more than one press ENTER okay then again this line and this speaker click on line then take your cursor to this endpoint track this endpoint zoom it click zoom - then make ortho on then click enter then for this speaker we will create this rectangle click on rectangle then take your cursor to this endpoint take it above click and take it on this right side and click then again click on line then take your cursor to this endpoint take it below click then make ortho off then take your cursor on this side and click then take your cursor to this midpoint track that point click enter then we will mirror it click on mirror select these objects enter then specify first point of mirror line it will be this end point click then take your cursor on the right side and click then click on no then zoom - so this speaker is also ready then this line up to this point and ahead up to this line again click on line then take your cursor to this endpoint take it above click then make ortho on then click here zoom minus take it below click then take on this side then we want to make it up to this line take your cursor to this endpoint take it below and click and press enter then we need same circle below click on copy select this circle enter click on this endpoint take it below and click on this endpoint enter then we will create this portion click on line then take your cursor to this intersection point take it below click take it below and click enter then zoom there and again click on line take your cursor to this endpoint take it outside and click click on this side and click and press Enter then we will mirror this click on mirror select this object enter then first point of mirror line we will click here we will keep some gap click here take your cursor on the right side ensure that your line is straight click and click on no then we want to extend it up to this line for that click on this line click on this blue grip take it below then we need to create it perpendicular to this line for that press Shift + right click then click on perpendicular and click on this line press escape so this is ready then we need one line here for a ground again click on line then take your cursor to this intersection point take it below click then take your cursor to this endpoint track that point click then take it below click enter then we will create this ground symbol click on line take your cursor to this endpoint take it outside click click enter then again enter take your cursor to this endpoint take it below click click enter enter click this endpoint click click enter enter then again create this last line enter then we will mirror this click on mirror select this object enter click on this endpoint take your cursor below and click and enter so your ground symbol is ready then this one we can copy this one click on copy select this object enter then specify base point here take your cursor on this side and click enter then we will create these two lines click on line take your cursor to this endpoint take it above click and take it outside and click enter then zoom it then again enter take your cursor to this endpoint take it below click then take your cursor to this endpoint track that point and click and press enter then click on this line click on this grip then click on this endpoint press escape then this line and arrow click on line click on this endpoint take your cursor below and click and enter then to create the arrow click on line click on this endpoint take your cursor on left side click then make Ortho Off then take your cursor to this endpoint take it below and click and enter then click on mirror select this object enter click on this endpoint take it below click and enter then to fill this arrow click on hatch select solid then click inside this arrow click on close hatch creation zoom - then to place these points for that we will use donut command click on draw click on donut then specify inside diameter of donut we don't want inside circle therefore here you will have to specify 0 enter then for outside diameter actually we will specify it freehand so click here and click here so it is around 55 then click on the points so I want here here And here press escape then next is one resistor here we can copy this click on copy select this object enter specify base point take your cursor outside and click and press enter then we will have to rotate it click on rotate select this object enter then specify base point take your cursor above ensure that it is straight click then we will move it click on move select this object enter click on this endpoint then take your cursor to this midpoint and track that point and click then we will have to trim this line for that type TR enter then select this line and this line as a boundary line then press ENTER then click on this object then press ENTER zoom minus then to create this water alarm sensor for that we will use ellipse click on ellipse then take your cursor to this endpoint take it below and click then make ortho on then click here take it above and click then one more ellipse is required inside we will offset this click on offset press ENTER click on this ellipse take your cursor inside and click enter then these vertical lines and this rectangle click on line click on this quadrant point take your cursor below and click and press Enter then we will offset this line click on offset then press ENTER then select this line and click on this midpoint and again select this line then this endpoint select this line this endpoint quadrant point enter then we need this donut we will copy it click on copy select this donut enter then specify the center point as a base point click then click on this end point enter then click on rectangle then click first point here and second point here then we want this rectangle to be Hidden for that click here on layer properties click on new layer then name it as Hidden then click on continuous click on load then scroll it down until hidden is shown click on Hidden ok select Hidden ok then close this dialog box then select this rectangle click here and click on Hidden press escape it is converted to hidden but gap between lines is very small to increase the gap type LTS for linetype scale enter then increase the scale factor suppose I will make it 5 Enter still I will have to increase it press Enter I will make it 15 enter zoom minus so almost everything is ready now what is remained is text zoom here then for text click on multi-line text then specify first point take your cursor on this side and click now here we will write this 9V then type plus nine capital V then click outside now this text is very smaller zoom it then double click on it then select the text and increase the size we will make it 20 enter click outside I think we will further have to increase it double click select it make it hundred enter click outside okay a little bit more select it and make it 130 enter click outside ok now it is alright and we will copy this text at every position we want click on copy select this text enter specify base point then make Ortho Off and click here okay enter then we will edit it for edit just double click on it and change the text so it is S1 ON/OFF SWITCH selecte then type S1 enter ON / OFF enter switch then we want this center aligned select this text and make it Center aligned click outside then this R2 56K double-click R2 enter 56K click outside then move it for move you can type M enter select the object enter specify base point take it above and click then same way here R1 10K R1 enter 10K click outside then move enter select this text enter specify base point take it above and click zoom - then this numbering double-click it then to adjust them just click on them then press first mouse button and drag it and release it just click then press first mouse button drag it and place it so in this way you can arrange them wherever you want them or if you are facing any problem with this you can also use the move command zoom - then here C3 47 mu 25 volt double-click C 3 enter 47 we will add that symbol 25 volt click outside then move it above click on move select this object enter specify base point take it above and click then to add the mu symbol double click then click here then click on the symbol click on this others then select the system font and here is the mu symbol select copy then right click here and paste then backspace and click outside so your mu symbol is added then we need one text here copy enter select this object enter specify this base point and click here then we need text here here and here then one text here then here and here enter so this is ground G N D click outside this is also ground click outside then for Speaker LS1 8 Ohm to 0.5 watt speaker double-click LS1 8 Ohm for ohm symbol click here on symbol and click on Ohm then comma point five watt enter speaker make it center align select it then click here on Center click outside then C2 point not one Mu double click select it C2 enter 0.01 we will increase the size of this box for that take your cursor to these inclined lines once it shows this inclined arrow press and hold first mouse button and drag the mouse then click here right click and paste So mu is already there again take your cursor to this inclined line press and hold and increase the size click outside then erase this E enter select this enter then we will copy this here copy CO enter select this object enter specify base point and click here enter double-click make it C1 Enter click then click on it drag it and place it then to water pipeline double-click then select it and make it center align click outside then water alarm sensor double click then to increase the size take your cursor to this incline line press first mouse button and drag it then below it enter mounted on water tap then I can increase the size press first mouse button and drag the mouse then make it Center align click on center click outset then move it before that we will increase the size of this text click on it click on this arrow and take it on the right side then move it press first mouse button and drag it and place okay then we will move this click on it then press and hold and drag it and place it here then we can stretch it and take it above click on stretch then click here take your cursor above click enter specify base point make ortho on take it above and click then move this type m enter select this object enter specify base point take it above and click then click on it and drag it and place it this VCC and R for that copy CO Enter select this object enter specify base point make Ortho off we can also press F8 to turn on and off ortho mode click enter double click type V CC then select the CC and make it subscript click then here is R double click click outside double-click OP O / P click then plus sign so for that again we can copy this text copy select enter base point click here enter double click and place plus click outside move it move enter select this object enter specify this point and place it here okay one more text is there this IC one LM triple 5 copy this one enter base point click inside enter double click and select it make it center align make it bold and increase size 150 Enter click outside then move it enter select object enter base point and place it in the center now everything is ready in the next lecture we will learn next set of commands and we will solve exercises based on it and we will continue our tutorials for electronics electrical chemical civil mechanical and interior design so thanks for watching we will stop here
