Hi Salvio,

My apologies. I missed the point that you are using Update12 of MicroStation. The Modify Facets workflow is not producing desired result on U12.

I looked for other options to get desired output. Trim surface by curves tool from Surfaces > modify Surfaces is helpful.

Workflow:

1. Draw 3 point linestring having splitting line on shape.

2. Start trim surface by curves tool. Dirn - orthogonal , Method - split surface , convert to Bspline Surface - off

3.Select shape and splitting linestring. Accept to generate result.

It produces two shapes.

Hope it helps...

Thanks,

Swapnil

Hi Swapnil,
I tried to follow your instructions but the result seems to be the same as using the Facet Project.
Maybe I'm doing something wrong?

Thank you,

Hi Jon and Salvio,

Behavior of Facet Project tool for shapes with concave angles is work as designed

Thanks,

It's not clear from your answer what Bentley Systems will do...

Raise a defect to fix the problem
Declare it to work as designed (WAD)

Hi Salvio,

Thanks for sharing file. Issue is reproduced. For shape with concave angles, facet project triangulates output mesh hence desired output is not generated..

To get desired output procedure can be modified a bit. Instead of facet project, use Modify Facets > Split Facet option. On mesh , define splitting line to split mesh similar to one used in facet project. Using drop command creates two shapes.

Thanks,

Swapnil

Hi Swapnil,
attached you can find the file I'm working on.
For completeness of information I would like to tell you that the version of Microstation I use is 12.

Thanks,
Salvio

Hi Salvio,

Following procedure mentioned on U14 MicroStation , I am getting two shapes when mesh is dropped from both workflows. It is not sure shape with concave angles is drawn like yours. Can you share dgn file with us to reproduce and review what you are getting?

Thanks,

Swapnil
