FreeCad - Modeling A Twisting Object Using Surface And Curve WB.

hello guys uh today I'm going to uh draw this object in free Cut so let's see how it look in free Cut so if you are like this design you can follow my tutorial so thank you okay so to start I create new uh document go to the Sketcher with PCH and I create a new SK in the the top view I create a hexagon start from the center I select this point and this point I hit V for vertical con I select this point and this point I hit L and set it to 50 also I create a center a re angle also start from the middle Center I select this line and this line and hit e for equal and also select this line hit L uh 7 now I can close that next I create another SK also in the front in the front view I create a circle in the red line and I select the circle and set the radius sorry the diameter to 15 I select this point and I hit L 25 now I can close that next I go to the prop bench I select the circle and I Revol it around the Z AIS make sure you uncheck the C unet it and click okay okay next we select this and is through it Ty it 50 and symmetric make sure you check the C because I want to use this one to cut the the Taurus and I click okay all right now I select the Revol and control select the ISRO and just cut it so now we have something this next we go back to the sketch workbench in the sketch workbench I create a new sketch in the top view and I create three line one line like this another one and the last one on the red line let me view the and I select this point this point and this line and I hit s for symmetry constraint I select this this line and this point and I set the constraint this line and this point and a set constraint also I select this line and this line and I set angle to 60 okay make sure these po are outside of the hexagon now I can close and now I select this SC 002 go to the par PCH and I will is through it to 50 symmetric and okay I next I select the cut and control select is through and I go to part SLI and slide aart now we have a folder and inside here is uh six pieces next I go to the Dr PL go to the utility and select PL and I set the top Okay click on the top and I want show to make a copy of uh this P I want to make a copy of this and mirror it to the other side so I have another copy in here all right and also I will make this uh make another copy of this one and mirror it to the other side I select this p and make sure you um uh turn on this uh snap lock snap and point snap midle point and snap Center just turn this guy on and you select this p and you click on the mirror tool click on it and then you click on the first Bo of the AES you want to mirror because I want the AES I want to mirror is uh this line so I will select this point and then select this point I select this point and I select this point now you can see we have another piece created next I select this p and also mirror it and this time I select this point and then this point I turn off the grid and I select this p and this p and I click on the upgrade you can see in the chv we have a new cell created next I will um P polar array this uh piece to six uh six time so uh I select the cell I go to um mod modification array tour and polar array and I type in here six and I click on reset point this is the center of the rotation I want it in the center so I click on the reset point and I click okay now you can see we have something like this next I uh select uh the array and shift select on of the slide in here and I click on upgrade now you can see we have a sound here I select a cell and I create a clown of this so we have another copy of this cell and I select the Clone and I go to the placement and position and I want to move this one up in Z AIS 30 and I also want to rotate this one in the Z axis 30° so I click on the AIS you can see default in the Z AIS is one is good now I type in here the angle effect okay so the next we need to do is I want to connect this circle and this circle with um a curved surface a blending surface first I go back to the Sketcher we and I create a new sket on the top view I create a line stuff on the center go out of this and I I will uh reference this uh line right here the section and I select this point and then this point I hit Ed for horizontal contr okay now the scat is fully constrained I can close that you can see this new scat is uh pointing uh right in the center of this circle next I want to make a copy of this Gap I select this Gap and I hit control C to copy and just select this Gap right here okay and contr V to past in it I select the new scap and I go to the position also I bring it this one up to 30 and also I want to rotate it and the Zs is 30° so you can see an another line here so the next thing I need to do is I want to create a plain curve between this line and this line let me rename this guy so i s this one and we will rename it lower body upper body next I just hide the lower body and the upper body now I go to the Sur workbench and the sh workbench I will control select this line and this line and I will create blank curve I want to bring this new blank curve from here to here so I select the blank curve and I set the star parameter to one and end parameter to one and I also want to change the and continuity to one and start continuity also to one and as set the inside to 10 you can say 10 go inside so I will change it to 10 and also St side to 10 okay so now I have a good PL to curve between this line and this line let me show the lower body and upper body and I will call this blank cve P okay next I go to the cowork bench for the cowork bench I will as turn this uh line and this line to be Jo C so I select this line and this line and I create chy curve doing the same down here select this one and this one and joy curve now we have to Joy curve I select the first joy cve and then turn that into the profile the Pyon profile click on it and select the second Joy curve and turn that into the profile okay next I can I control select the part in the viewport and come over here control select the profile and profile 001 and just pyo I click on the pyo and I go to the data the mod to FR it the output should be the surface at the correct show let I go to the Dr Pinch and also I select the pel go to the top view and I go to modification aray to and Po aray and to click on reset for and type in here six to okay now I hit ship B to select everything and I go back to the cwork bench and I turn that into J the solid I select the solid and hide it it's SP bar to hide it and I hit shift B and I select on of this guy and also HDE it this SP bar to HDE it and I bring back my solid I select my solid and hit contrl D and I set the material to Chrome and also set the shap color decrease the sh color and I hit close and I also select the solid and go to the view CH the deviation down to 01 0.01 enter so now this is the final result so thanks for watching
