Almost every time I extrude something I like to keep it as a separate body before I join it to the rest of the model. Even so, I often forget to switch my extrusion to “New Body” before accepting the change, sometimes more than once in a row! (cognitive issues).

I think it’s many times easier to do a “Union” operation after the fact, compared to a “Split Face” (or undoing and redoing the extrusion), and for that alone feel like default extrusions to “New Body” would be the “safer” or less impactful option of the two.

I don’t know most people’s workflows, perhaps this has impact I’m not considering. I wouldn’t say this is a blocker, but it definitely slows me down, and defaulting to New Body would make Shapr3d ever so slightly more accessible for me!

I saw this related request, but it’s gone unanswered and I don’t know “necro” etiquette on this forum. It does help me feel like I’m not the only one, though 🙂

Thanks for listening!

Agreed, I tend to want to make separate bodies using the primary as a reference

That’s a good suggestion. Countless times I have wanted to Extrude as new body, but forgot to tick the option. A default new body would work well for me.

Is it even possible to tick a box on iPad Pro to create new body VS. union? I don’t see that option anywhere and am also super frustrated at having to draw construction planes that are offset every time I want to create a discrete body, and then move the body afterward to be in the right location— vs just sketching on a face and making a new extrusion as a separate body.

Yes, it is possible. It’s right next to the dimension.

> You can use the Extrude tool to create 3D geometry by pushing or pulling a face or closed sketch in a linear direction. If necessary, you can specify a draft angle, which adds a taper to the side ...

In HBPM beta you can change the result method (and other parameters) _ **after** _ the operation is complete. It is pretty slick! You can check it out in the public beta.

Agreed it’s very useful to be able to use the history sidebar to make a new body this way. I’d still prefer an option or setting to make “new body” the default.

Agreed. It was not at all clear what was going on with this when I was first learning Shapr3D, and it very nearly caused me to abandon the tool completely because is kept horking up the geometry I was creating using the methods shown in the tutorials.

Worse yet, I’ve lost a half day’s work by not realizing it had stupidly glued the bodies together, and I had to go back and nuke and recreate everything that I’d done after that point.

Much of what bites you in the ass in Shapr3D is stuff that has no obvious workaround. There _usually_ is a workaround, but not always, and even when there is, it can be well-hidden, like this one - if you don’t remember to change this setting before extruding off an existing body, you’re just hosed.)
