How to split a surface from rectangular pattern feature occurrence

SandmanINV — Tue, 03 Jul 2018 10:56:33 GMT

Hi everybody,

I have a surface with random boundary. I want to split it to many smaller surface. But i can not find out the way quickly.

Currently, I import a autocad file, create a boundary patch surface, create a rectangular sketch and extrude surface.

Split extrude surface. Pattern extrude surface to continue split.

But now, i can not split from pattern elements. How should i do ?

Thank you.

Here is my code.

Thank you for your help. Here is my picture. I split by hand in this file.

could you show me the picture without the splits too?

Hi,

Thank you for your idea. I opened your file. But maybe i am stupid. I don't understand what you mind ?

like my picture i uploaded , i want to split a surface with random boundary line.

My way is extrude surface and split mother surface tho many child surfaces automatically.

After saw your part, i dont understand how to solve my problem...

Thanks you.

Hi,

I tried it to do a different way.

I made the separate surfaces already and then I made the pattern.

This is much easier regarding the split method. because you don't need it, to my opinion.
