Place point at object's gumball origin

[lander (CAD CAM CNC)]

I’m not sure how to search for this if there’s already a thread or solution.

I’m attempting to do an operation whereby I perform a ‘wirecut’ and I’ve noticed I’d like to reference the curve objects origin where the gumball seems to be, because the depth of this location needs to be referenced relative to that.

I might be able to reference this depth differently, so maybe I’m over complicating it. I might have to just move the curve specifically to a vertical dimension first idk yet.

It’s just that there’s no way to obtain an area, or volume centroid of a 3D curve…

Oddly the gumball seems to know where it is…

Yeah looks like I can just move the curve vertically first to specific dimension …

You can also set the cplane to gumball and place a point athe the cplane origin

Thanks for the tip!

I’ve been tryna tackle this problem where I’m developing mold geometry, and there’s these micro under cuts, and it’s making it overly difficult to do simple extrusions and booleans.

So, I’m trying some wire cuts and that might work. But I’m afraid I might have folded faces

Looks like it worked, but a couple planar surfaces are transparent.

Hi,

There are various ways to get and use the gumball center point, this thread has a few macros and python/VB scripts though it looks like you solved your problem.

Feature Request: Rotate from Center Without Gumball

I’m assuming there must be a way to do this that I don’t know about… Right now I end up making a centerpoint using areacentroid and rotating or using the gumball, but it would be nice if I could just a FromCenterpoint option nested within the Rotate command.

gumball drops at the bounding box center by default unless you move it.

you can always run the boundingbox command and use osnaps to find the center.

notice in the video below gumball does not move whether I select the bounding box or the object

lol awesome! I wasn’t thinking about the bounding box

I haven’t had lunch yet, still need to feed my brain… getting 's now.

Thanks for sharing. I’ll check that out too!

hmmm did an explode edge rebuild sequence and found some strange triangular anomalies from the wire cut.

Maybe I can improve the curve or something idk.

I’ll have to create some kind of sample file and new thread if I can’t figure this out.
