I have a surface model in IGES and STL formats. the model has domes and holes with different shapes (circles, squares...etc) in the middle. Is there any way I can determine the boundaries of the wholes model and the holes only, and meshgrid and surf the whole surface except the wholes ?

Thank you so much

What's the necessity to meshgrid and surf? You can surf the stl data itself.

because I want the surface grid data. with a specific grid size. hope you can let me know if this is possible without meshgrid.

You can interpolate to your desired resolution/ grid size using griddata or scatteredinterpolant

sorry for the late reply, I just don't get notifications on comments. only on answers !!!

Is this what you asking for ?(attached)

And after surfing it, Is it possible to convert the IGES to image so we can use (bwboundaries) to find the boundaries of the whole part and the wholes in it in XY dimensions ?

THANKS FOR THE HELP
