Hi all,


I have a CAD file as shown in the image below. It is symmetrical about z-axis.

I need to trim the CAD into half and delete surfaces in other half.


Can anyone suggest the logic to select the surfaces in any half, i already have the code to split in half.

Hi Vipin


You can use "by block" option in *createmark.

Here is sample code.


set blockname [::hwat::utils::GetUniqueName block "Dummy"];
*createsimpleblock $blockname 11 -100000 -100000 0.5 100000 100000 100000;
*createmark surfs 1 "by block name" $blockname;
*numbersmark surfaces 1 1;
*createmark blocks 1 "by name only" $blockname;
*deletemark blocks 1;
