How to Move Multiple Objects Slightly Towards Origin

jpvonhemel — Sat, 05 Feb 2022 23:34:51 GMT

Hello,

I am adding some extruded text to an STL and have hit a roadblock. The object is circular with some nubbins around the edge to help with grip. They appear to be connected but on join failure, I zoomed in and noticed they are not touching. There are 90 of these as individual bodies.

After a lot of failed attempts with move, I figured I would ask how I can select all of the 90 objects and then shift them towards the origin by just enough to get them to touch and thus join to the main object.

Thank you,

Jerold

Your conversion from mesh to BRep is not ideal. Given the geometry is simple I suggest you redraw it with solid feature (a hollow cylinder with circular pattern of extruded nubbin).

@hamid.sh.'s comment is valid - "faceted" mesh to BRep is not a recommended workflow.

But, to answer your specific question: No, there is no way to move multiple objects in different directions. Move works by constructing a single transform and applying it to the selected objects - so, they will all move in the same direction.

I figured Fusion 360 was not very fond of the model, considering it converted it into 91 bodies.

This part has threads on the inside, and I am not familiar with creating them, so my thought was to shift 90 nubbins towards the center about 0.1-0.15 mm. Guess I should learn how to recreate this from scratch. It is probably easier than I think it is.

@jpvonhemel It's not a matter of having 91 bodies, but faceted mesh. Fusion is a technical CAD primarily made for creating and editing BRep solids.

I think it's pretty straightforward to make your model in Fusion from scratch. Once you make your cylinder, if the thread is a standard one you can use Thread tool (with Modeled option) on cylinder face to make the thread. If it's not standard, Coil comes is handy.

That being said, you can modify existing model like this: delete all nubbins but one, move it into the position you want and then circular pattern it (as a body) around the center. Still I don't recommend this, you'll have much cleaner model if you create from scratch.
