Addon for importing STEP files into Blender for macOS only.

Inspired by its equivalent called stepper for Windows, STEPmac produces a mesh based on triangulation of the underlying surface to import *.STEP files into Blender.

Current Version: 1.0.4 (macOS only)

Tested on macOS Sonoma 14.4, blender 4.1 & 4.2 (last version).
It should work with older macOS versions.
Compatible builds for Intel or Apple Silicon (M1, M2, M3) processors.

Install procedure:

1) Download the file after purchasing

2) Open blender. Go to Edit > Preferences

3) For Blender > 4.3

Select the downloaded ZIP file by clicking on the INSTALL button

Then click on INSTALL FROM DISK

For Blender < 4.3

Select the downloaded ZIP file by clicking on the INSTALL button

And, select the STEPmac ZIP file you just downloaded.

4) Search for STEPmac in the list and don't forget to tick the box to enable the addon

5) To import a STEP file, go to File > Import > STEP (.step, .stp)

6) To open the STEPmac menu press 'N'

Troubleshooting:

1) Mach-o file error

ImportError: dlopen(/Users/.../STEPmac/OCC/Core/_BRep.so, 0x0002): tried '/Users/.../STEPmac/OCC/Core/_BRep.so' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64'))

If you have a mach-o file error on the _BRep.so file, this probably comes from a wrong choice of Blender version based on you mac chipset. Note that you can install Blender version intel on a silicon chip and the macOS will emulate... So, reinstall Blender with the correct version:

• Blender Silicon on silicon chips (M1, M2, M3 ...)
• Blender Intel on intel chips

2) Octane rendering

Currently, the plugin is not working with Octane rendering. It needs to use the built-in rendering Cycles.
