So it will only increment by 1 in your GDL script, 1 is 1 meter so that's why the dynamic hotspot moves like that.</P> <P>&nbsp;</P> <P>So the solution would probably to drive the dynamic hotspot with a length parameter and then deduct "sl" from it so you can use it in your loop.</P> Tue, 03 Oct 2023 18:10:27 GMT https://community.graphisoft.com/t5/GDL/I-have-written-a-GDL-for-aluminum-square-tubes-but-cannot-solve/m-p/400624#M5704 MetalFingerz 2023-10-03T18:10:27Z
