Sculpting environement

[jrinad70]

So, once I've created a form, added thickness to it (say 1mm), clicked on finish form (or just clicked ok on the thickness command), is there a way to go back and change the thickness value?  What if I typed in 1 mm and meant to type 2?

Thanks,

Rich

No, nothing in the sculpt environment is parametric.  You have to make those changes by hand.  You can exit the sculpt environment, and then thicken the resulting brep surface body.  That would be parametric.

As @laughingcreek already mentioned, the model workspace is not parametric, so you don't have user or model parameters that you can change. But you can right-click your mesh icon in the timeline and edit the body.

I understand Sculpting is non parametric.  I was hoping though if one went back into the sculpting environment one could at least perform an undo, just like he can while performing the sculpting in the first place prior to clicking Finish Form.  The software records the steps while creating, why not just keep the recording of steps to walk backwards at any time?  Basically if someone spent 100 hours sculpting a Formula 1 body, performed a thickening command applying a thickness of 1mm, but meant to type in 1.5 mm, clicked on finish form, that person just wasted 100 hours of work and has to start all over?

So, is there a command or technique in the modeling environment (or sculpting environment) to return the thickened surfaces back to "surfaces" that have no thickness?

Undo is only recorded for a session.  That information is not persisted with the design (if it was, the size of the design would be huge).  Within a session, you can undo, certainly, but understand that undo is design-wide.  So, if you do an offset in Sculpt, then return to Modeling, and do a bunch of operations,  you can certainly undo all the way back to that offset, but you will also have undone all the Modeling operations.  There is no per-body or per-workspace undo stream in Fusion today.

Probably the best way to approach this, if you want the ability to modify the thickness later, is to use Thicken in the Model environment.  This will produce a fully-parametric solid from a surface body.  Just a warning, though, the Model Thicken is a precise offset (meaning it guarantees uniform thickness), so it is expensive, and can fail with complex geometry.

If you need to change the thickness in the sculpt environment, you can select the face loop that is created in the process of doing the thicken, and delete them, that will separate the original surface from the offset/thicken surface.  see screen cast.

Thanks for all the input from everyone!!

It doesn't look like the screen cast attached.  Here's the link

EXCELLENT!  Thanks a million!
