Working in parts or sketch studios

mario_darceuil

I have to extrude this image; then move (transform) the legs around to add more material to house motor mounts. Do I do this in parts or sketch studio, this means that I would have to extrude lastly?

I am thinking the parts studio may be right for this, Please help.

Either way really.
I would think extrudeing the legs separate, then move them around with transform

Then boolean union as desired.

manipulating sketches can be more of a hassle especially when you want all coppies to be identical but translated/rotated by a little bit.

Someone correct me if i'm wrong but I think sketches can be more expensive than 3d objects

So I add a line to cut off the legs as a separate face, then extrude them separately? How do I bring body and legs together again as one item. You did mention 'transform union', I'll have to look it up. But wouldn't two separate extrusions give two separate parts on two different sheets?

You may want to check out this video:

Or go through some of these training courses:

(Fundamentals 2, 3, and 4 may be the most useful for you right now)

I'm not sure what you mean by "two different sheets", but two different extrudes will give you two different parts (as long as you select the New option in extrude rather than the Add option).  These two different parts can happily coexist in the same Part Studio (Onshape Part Studios are inherently multi-part).  Once you have the legs and body as separate parts, you can move the legs to where you want them using the transform feature, make additional parts to house the motors, and then attach it all back together using the "Boolean" feature:

Fundamentals 4 is a really good training set to learn about how to model in Onshape's multi-part environment.

Good luck! Please feel free to post more questions as you go along.

Two different parts indeed.

Yes,boolean is a powerful tool in onshape.
