Does anyone have a lisp prog to sum the lengths of lines in Autocad 3D model space ? ie to get the total length of all lines in a 3D model (for calculating the length of handrailing). Thanks

I believe you can select them, and total length will be displayed in the "properties manager", after you select object type of "line". If you ant a lisp, lots of routines available for summing lengths. Probably one at this site. I recal TOTLEN.LSP by Paul Turvill eons ago...

Thanks CarlB
I only have licenced 2000i here at  home (it doesn't give total length for lines) but will try it at work on Monday. Did you check it with your version ? Regds  Des

But TOTLEN.lsp is GOOD ! Thanks
