Split a Body That Is Not Joined

[Anonymous]

I imported a design as an STL and converted it into BRep, however it converted into one body, despite there being five solid shapes. I need to split these however after adding a plane between them and trying to split the body along that, it won't let me as there is 'No intersection between target(s) and split tool.'

How would I get around this?

Thanks

Why not delete 4 before conversion and then copy?

Why use stl of such simple geometry at all?

Stl is rubbish for engineering design - model as native geometry.

Stl is for printing - and end product of design.

It was all one body before the conversion also so I don't know whether that would make any difference.

It was a STL file as I designed it in OpenSCAD for accuracy and scalability purposes however I would like to import it into fusion so I can sculpt it and change it slightly easier. I know it's not ideal but that's all OpenSCAD can do really.

You apparently have Fusion?

I don't understand the issue?  You shouldn't need this "OpenSCAD" that you speak of.

Can  you Attach your original *.stl file here?

In the time you've already spent trying to figure out how to work with this .stl in Fusion 36-0 you could have easily remodeled this part in Fusion 360 with CAD accuracy.

I'd take that advice- model the part in Fusion.    You've done part of the work already, importing reference geometry.   Free expert consideration of your problem- supplying the requested file should be a no-brainer.

I've found that if you convert the mesh to a brep and then make one side of a face healed by deleting the extra geometry you can use split body to separate floating objects. While it's not ideal to do this sometimes you have to work with a mesh that has many objects in it and they are not always repeat objects but many unique bodies as a mesh and it would be a ton of work to redraw them all depending on the geometry involved and the number of items involved. Splitting the converted body can be much faster if you can get it to work.

This is how I did it.
