How to make this object?

Hi Juliet,

please be aware this is MicroStation Programming forum, but it's not clear whether your question is user or programming question. Also, you did not provide any information about used version (MicroStation full name + build number).

Because of that, I recommend:

• Read and follow community best practices (expected subject format and set of necessary information etc.) that all together helps to make a communication more efficient.
• Edit your question and add details about used version.
• When your question is about "how to do it using user tools", move this discussion to MicroStation forum. To move existing discussion, use More > Move tool available under your original post.
• When your question is about programming, specify what language / API you want to use.
• Plus, also please provide (attach to your post) DGN example with expected result, because in 3D, especially in MicroStation CE, a question is whether normal solids can be used or it's expected it will be parametrized somehow etc.

With regards,

  Jan
