Project external details onto sketch

Post by keltel »

Hello.

In this example I have used PartsDesign to draw a rectangle and padded to form a baseplate. I then used A2plus to add a bearing block and align it to the baseplate as required. I would now like to be able to project the 5 holes (4 mounting, 1 for shaft) from the bearing block to the baseplate so I can add these holes to it. I have tried "Create an edge linked to an external geometry" but cannot select anything on the bearing. Is there some way to do this?

TIA, Kel.

1) Make Body active (right click in tree toggle active body)
2) Select desired edges:

3) Create blue shapebinder
4) Hide everything except binder.

5) Open sketch, add links to external geometry.

Thank you!! After this is it necessary to add the actual holes manually? Those circles come up as red lines, not the standard white / green lines, and don't affect the pad.

Also, when i try it the larger middle hole did not show up in the sketch on the first try, but it did when I closed the sketch and re-opened. Funny.

Yes, you add the holes manually taking the center and radius from the external geometry.
