Fusion 360 problems (3 Tools You Must Know)

what do you do when you have a sketch that won't extrude or won't fully constrained hey this is tyler back with tekken espresso today i want to talk about three tools you can use to troubleshoot your sketches so the first thing i want to talk about is can you extrude it now this is basically a fully defined sketch it almost is it's almost completely done and we'll talk about that in just a second but say your sketch looks something more like this no dimensions maybe a few constraints this is still acceptable in fusion and when you're early in your design phase this is totally fine because you can drag it and move stuff around the reason that we fully constrain and dimension things is that when i make a change that it's going to update but still obey the design content or intent that i have it's going to edit well that's the key with adding dimensions and constraints to make everything fully constrained and fully defined it's fully defined when you know that there's a little lock and everything's turned black so this sketch isn't fully defined but let's go back over to this example will it extrude if you hit e for extrude or revolve if it's extruding that's good that's a good sign and the entity itself is shaded when it's not shaded for example when i look at this i hit extrude nothing happens i look for shading there's no shading that's a bad sign so first tool is the line command technique what i like to do is come in with some sketch lines you can do one or two and i did two now these two areas are shaded meaning they are good there's no areas of concern or errors or problems my problem is somewhere over here now if i drag the line and i could even bring in another one delete that and maybe sketch a line going across so it's starting to kind of like narrow in so it's somewhere in here this area has the area where the problem is so multiple different techniques you can do you can delete lines and entities you can zoom in and investigate when i zoom in i can see that i did not complete or for some reason these were not made coincident so if i drag it and make it coincident now the sketch is fully shaded that's a great thing you can delete those lines so first tool use the line technique to find problem areas in your sketch number two the drag it method so this pertains more to when you want to fully define a sketch so you've added a bunch of dimensions you've added a bunch of constraints but yet you don't have the red lock and it's not fully black okay so what's missing so when i drag at this blue line i'm gonna delete this dimension see what's going on here so when i drag around okay it's not actually constrained to this point so i'll select the two points sometimes the dragging works sometimes it's better to select the two points and choose coincident now they're locked in and if i drag now the distance to the horizontal is missing so do i want to define that sure let's set this angle or set this distance of 15 it's fully defined all right let's look at another example so when i drag this one it looks like it's moving off to the side so i can perhaps put in an angle dimension to lock that in or maybe even a horizontal distance let's try putting in an angle and there we go it's now fully defined the red lock showed up terrific much better so what i want to show now is one that pops up kind of often when you add sketch fillets to a sketch i found that if you sketch something like this but add the sketch fillets after the fact let me show you what that looks like so we add a fill it to this corner it's going to add that in and add a radius and that's perfectly okay to do on your sketches if you want to do it here but i have found sometimes added getting this fully defined can be a little bit trickier now i want to introduce there is the drag it method which is my favorite and when you when you're not able to drag sometimes i like to go in and delete and then move things around and figure out like what's missing so you know i think if i were to put an angle here that should fully define it much better now is there a way for fusion to list out what's not defined and you actually can and this is shout out to kevin kennedy great job showing that video with the command line so i want to introduce that on mac it's option command c select all three and then you can type in your sketch command the sketch command is sketch dot show under constrained hit enter that'll pop up the way you find this on windows it is ctrl alt plus c for windows so once you have your command line type in this command and it's saying that i have three points and three curves under constrain that is highlighting what i already knew which is the problem was somewhere in this area where the blue lines are where this can be helpful is when someone accidentally sketched a line on top of a line right or you have multiple entities showing up and if you'd like to rerun the command press up it'll pop that command again in your command prompt click ok and it looks like i have it's showing me additional points i like that capability that it's showing me kind of that there's a lot of extra stuff going on here so if i were to come in here and select this little line delete it now it's still the same problem of what is moving and how do i get it fully defined so i'm going to come in and add a dimension like we tried earlier an angle hey so in the comments below let me know where fusion 360 messes you up as far as sketches constraints where you bump into errors where that seems to show up love to hear that love to hear your questions thanks for watching catch you in the next video
