  1. I m trying to make a selection set using a point and a couple of lines passing through this point (caution, NOT terminating). I want to select lines of specific layers. What I m typing is this (setq pt (getpoint "\nSelect point: ")) (setq ss (ssget pt '((0 . "LINE") (8 . "mylayer")))) Unfortunately this doesn't work. The only way I could find is to use this instead (ssget "C" pt pt '((0 . "LINE") (8 . "mylayer"))) However I do not find that helpful at all. If there is a line at the back on an other elevation, not crossing the initial line, but coincidentally passing 'visually' through this point (pt) the later ssget command will include both and that is not what I want. How could I use a point and filter together? Any help would be appreciated.

    Selection Within a Block

    I need a way to select everything but the centerlines within a block. They extend beyond the part which I hope to find the actual envelope dimensions of. I will then iterate through the remaining parts to find the max/envelope dimensions. The issue is this block is in a document with many other objects (blocks, lines, points, etc.) so exploding is not ideal as it would be a pain to recollect the parts. Also opening a seperate file is too time consuming, this must be done within the file at hand. Is this even possible? EDIT: Oh! A little drilling, and you can easily and directly access a block within a document, then iterate through them as I mentioned above. No inception-style selection sets needed! Nice. Looks very roughly like this: Dim blkTestBlock As AcadBlock Set blkTestBlock = AutoCAD.Application.ActiveDocument.Blocks("ACT1") For Each ACADEntity in blkTestBlock If linetype="Continuous" then getboundingbox....blahblahblah
