STEP import with wrong names?

Rhino
1

Hi all. I do need to import some STEP files that are generated from SolidWorks and unfortunately I do have an issue with the names of the imported parts that seems to be different than the ones of the parts from the STEP file. I do made some tests and looks like Rhino imports the STEP files without the original names.

This is what StepViewer says about the part names on the STEP file:

STEP_file
STEP_file1006×1046 44 KB

And this is what Rhino is naming the same parts imported from the same STEP file:

Rhino_STEP_Import
Rhino_STEP_Import741×607 58 KB

Note than while in the STEP file the parts are named “J.01 Upper Carcase Vertical LED Profile 17 x 8”, after importing them in Rhino7 the names of the same parts are now “Boss-Extrude1”

I do tried to use the script from this page How to import a step file with part name in Rhino7? - #14 by Macuso but unfortunately the parts are not imported correctly this way, they are scattered all over the place and the Pancake (ImportFrom) component it is giving-me only after the first 298 parts.

It is possible to fix this STEP naming import issue? Thank you.

The name you are referring to is typically assigned to a block. In the case of STEP files that contain a single block instance with an identity transformation matrix, Rhino imports the block’s geometry but not the instance.

If you want the 2 solids to import as a single block with its name the same as the file, _Insert the STEP file instead of _Import or _Open.

This is just a small example. I do receive entire assembly parts with a few hundred different parts created in SolidWorks and all the names of the parts are screwed. I do tried the _Insert way and still the same.

Hi -

Can you post an example that comes into Rhino as a block?
