Hello everyone, i’ve got issue while trying to modify a design that has been created in Rhino. Basically I can’t adjust or blend it. I see it as a solid piece but once I want to substrac or union another piece it sayss sheet body can be modified / selected.

Thank you for your help with this.

Hi

From the error message, it looks like there is some sheet (means zero width body) in the imported model. Shapr3D handles only solids.  
If your imported model has several items, try to find and delete the one(s) with no width.

Hi,  
Maybe also a surface issue that Shapr3d does not manage.

Agree with the people above, looks like from the error message its not solid.

Instead of merging with something complicated test it out by boolean with a simple shape like a square.

I use Rhino, it lets you save as STEP and other CAD format even though its not solid.

Check the model in Rhino using the _Show edges_ tool. If you find any _naked edges_, fix them until you get closed/solid polysurface after selection.
