Problems encountered during use #24

Hi Kai,

When I use BCB, the System Console Window always stays at the step of "Starting splitting process ...". My computer has a good configuration, so I can't figure out the reason. Have you ever encountered this situation?

Looking forward to your reply.

Hi Pierce,

The discretization usually gets stuck when too many objects are created. This can happen, for example, if the original geometry is not "clean" and is therefore broken down into individual surfaces.

The best thing to do is to check your input geometry to see if it is manifold (as in doesn't contain non-manifold elements). Otherwise I would have to take a look at it.

Good luck.

Hi Kai,

I checked the System Console Window according to what you said. Discovered an output of "Non manifold elements found: 81" during the first separate loose. How can I solve the problem of Non manifold elements?

Thanks.

Currently there is no tool to easily clean many objects. Typically, removing doubles (vertices) or converting the meshes to convex hulls are the easiest ways to fix bad geometry. You can either do this by hand object by object or write a script for it. However, there may be other reasons for non-manifolds that may not be so easy to fix.

The plan is to implement a cleanup tool to automatically create convex hulls in a few days. You're not the only one with the problem.

Thank you for your answer and help.
