Is this a mesh model? Is the boolean failing in Rhino or in Shapr? Is this data exported/imported from/to somewhere? Can you please describe what and how you are trying to achieve?

Created the elements in Rhino 5. The centre part I created a profile to sweep on a rail. The end cap I blended surface to close the top.

Ah. OK. Got it. Then probably you can get better help on the official Rhino forum: [https://discourse.mcneel.com/](https://discourse.mcneel.com/)
