Hi everyone,I have a problem with the Mesh functionality:By applying the procedure to a Shape that does not have concave angles, the split of the shape according to the defined division lines is correct as in the figure ShapeSplittedOK.JPG.
If instead I try to apply the same procedure to a Shape that has concave angles the result is somewhat strange, that is, the Shape is not split only on the basis of the dividing lines but dividing lines appear, ranging from the vertex of the concave angle to the nearest corner, dividing in this way the original shape in N additional triangles as in the figure ShapeSplittedKO.JPG
The procedure I follow is as follows:- I select the shape with Element Selection- KeyIn -> FACET CREATE- Double click on a vertex of the shape- KeyIn -> place line - I apply the dividing line between two points of the shape perimeter (only one line)- I select the shape with Element Selection- KeyIn -> FACET PROJECT- Double click on a vertex of the shape- KeyIn -> DROP ELEMENT- I select the shape with Element Selection
The settings of the FACET CREATE, FACET PROJECT and DROP ELEMENT are shown in the attached screenshotsMesh_Settings.JPG (FACET CREATE)
MeshProject_Settings.JPG (FACET PROJECT)
DropElement_Settings.JPG (DROP ELEMENT)
Has anyone already faced this type of situation?
Thanks for help,

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
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

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.

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

Hi Jon and Salvio,
Behavior of Facet Project tool for shapes with concave angles is work as designed
