Hi everyone: Ive create a geometry using lines and then putting the together with List.Create and List.GetItemAtIndex, so i could select a group of lines and then extrude the lines. However this seems to work perfectly but only with one selection of the list, i want to extrude all selectios from values X to X at the same. Any ideas. Thanks ![](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/8/5/8507a486cfd29cc6f9daa285837e8aaa4d7726ac.JPG) ---

Hi @samuel_barcenas, Try changing the lacing on the getitematindex by right clicking and selecting lacing. Cheers, Dan ---
