Sketch a rectangle, add circles for rounded corners and trimmed off the excess.
add construction lines
add 1 circle for screw holes
add some variables for various dimensions
used Mirror twice to get 3 copies of the screw holes
Extrude
Chamfer the screw holes
Fillet the edges
Shell out the backside
Worked great!
I then realized I had forgotten the holes for the switch, so I tried to go back and add two rectangles to Sketch 01.
However, nothing I tried would get the rectangles to turn into holes when the Extrude was done.
My question: after doing an extrude on a Sketch, can you go back in time and add new features to the sketch, and have them also be extruded properly (e.g. turning into a hole in the extrusion?)
Thank you - watching the video closely, I see you did these steps:
Clicked the hide icon on Body 01. Question: is that necessary? or just for convenience so the body doesn’t get in the way?
Clicked the Sketch to edit it, added a new shape (circle). At this point, the extrusion does not include the new feature - this is what I experienced too.
Clicked the Extrusion, clicked ‘Edit’.
Then you clicked the new feature (the circle) – at this point I see an error message pop up (Operation failed because the resulting body wouldn’t be valid)
Then you clicked back to the body shape, and at that point it seems to work.
When I was doing this, I did step 2, but did not do steps 3, 4, or 5. I assume this explains why it didn’t work for me.
Can you explain what’s going on in steps 4 and 5? Specifically, why did you need to click on the new big circle, but you did not need to click on the existing small circles again?
Errors appear because no profiles were selected at that moment. If there had been more than one profile, clicking one of them would have left the others selected, so that wouldn’t have caused an error.
Now you gave it a new profile to extrude.
You don’t need to click the big circle. I clicked a profile that was previously selected to deselect it. Also, you don’t need to click the small ones because they don’t need to be extruded.
After editing a Sketch to add or change features, if you want an Extrude to include the new features, you need to Edit the Extrude, Edit the Profile and re-select the face you want to extrude. This will include any newly edited features. If you don’t do this step, the Extrude step remembers the prior Profile you used, which will not include any of those subsequent edits.
