Hot to work with boolean result in a part design mode in 0.17 version?

Post by ShurikMur »

Hi,

FC 0.17, build 8264

Still didn't fully understand the new concept with body / parts in part design mode!

The problem:
1. Create one body;
2. Create second;
3. Perform boolean between them in part workbench -> get boolean result, that in no longer a body or part;
4. Want to work with that result in "part design" workbench, but at best it somehow copies one surface to a new body to create sketch on it, but it is separated from the actual thingy i want to work with...

A PartDesign body is a single part in its own, all modeling steps are inclosed in it. Hence it is not intendet to be used the way you did. If you want to bool two bodies there is a special boolean tool for that in PartDesign, this allows to work further in the main body with a second one fused/cut in. But again, in general this is not the intended workflow for PartDesign.

It is of course possible to further use a body in PartWorkbench, but than you really should know what you are doing and what the consequences are.

Let's assume I know ;)
Now, how to properly do this?

just select the fusion and create a new body.

And than rethink your modeling strategy as most likely there is a better way to do it 8-)

Great!
Big thanx :)

I keep in mind different approaches, but in that particular case - i think it is the most optimal solution... )

I'm just curious here, as I don't actually have anything that needs booleans in PartDesign - but would like to understand the intended workflow anyway!

Let's imagine I want to make an object, which is a cube with a lofted shape subtracted from it. Is there some other approach you would suggest rather than booleans in that case?

Yes, use PartDesign boolean.

This topic is about 0.17 only and there there is no PArtOperation you cannot do in PartDesign.

Part Offset for one thing. Part Section for another. Shall I continue? :D

:lol:
Those two don't make much sense in PartDesign, as they don't produce solids, but in I'm quite sure you can find some weak spots. Let's say there are some missing tools which should be considered as bug :)

I beg to differ. ;) Part Offset produces a solid when you check "fill offset", which is something that could be of use. I agree Part Section does not produce a solid, but does produce a 3D wire than could be of use in Part Design for a sweep path for example...

Okay, I will make reports then :D
