BG Posted September 10, 2015 Share Posted September 10, 2015 Hi Can someone please confirm - does the split tool work on extrudes? I seem to recall it used to, but it's not working for me now. Thanks Quote Link to comment
zoomer Posted September 10, 2015 Share Posted September 10, 2015 (edited) It works for me here. You'll get 2 "Solid Section" (In front view -> Line Split Mode + All Objects Mode (or select one first when in Select Mode) If that doesn't work for you for any reasons, convert the Extrude to a Generic Solid first.

Kevin McAllister Posted September 10, 2015 Share Posted September 10, 2015 You have to use line split mode or line trim mode (the second and third icons in the mode bar when the Split Tool is selected). The first mode won't work on extrudes. Kevin Quote Link to comment
BG Posted September 11, 2015 Author Share Posted September 11, 2015 Thanks, I had selected 2 polygons in plan view, then extruded them. The split tool doesn't work on the resulting extrude. If they are extruded separately the split tool works fine. Brett Quote Link to comment
Pat Stanford Posted September 11, 2015 Share Posted September 11, 2015 There was a thread recently where we "discovered" that the split tool can not be used to convert a closed poly to an open poly. The user was trying to use the split across just one "leg" of a poly and it was not working. If he drew completely across then it was fine. For your extrusion of multiple polys is something similar happening? Quote Link to comment
BG Posted September 11, 2015 Author Share Posted September 11, 2015 Hi Pat I've come across that issue too. Be good if the split tool split everything. It makes a difference if extruding 2 or 3 polylines together. 2 works, 3 doesn't. Converting the extrude created from 3 polylines to a generic solid made no difference. Can't use the split tool on it. Brett Quote Link to comment
Kevin McAllister Posted September 11, 2015 Share Posted September 11, 2015 Brett, Out of curiosity, does your cutting line cross the extruded shapes or just the space between them? Can you post a file containing an example extrude? You could ungroup the extrude and then slice across the objects with the Split tool (ungrouping an extrude made up of three separate 2d shapes separates it into 3 separate extrudes).

AlanW Posted September 11, 2015 Share Posted September 11, 2015 Thought the split tool cuts through everything. Just drew rectangles 3d extruded polygons and rectangle, rectangles, wall, windows etc and when I drew a split line across all of them they all split along the line, It destroyed the windows and I was only left with lines. Am I missing the point??? Quote Link to comment

Brett That VW behavior of Solids resulting in a Single Solid that contains many independent, non-touching Objects is the most annoying "feature" I have ever seen in any CAD application.

I actually love this feature and use it to my advantage all the time. Its easy enough to use the Ungroup command to separate them into individual extrudes. (A simple example - draw a simple table with an extrude for the top and 4 legs extruded together. If you want to change the height of the table, you only need to resize one extrude, not four.)

Am I missing the point??? I assumed it cut through everything too. I tried with a window in a wall and the results are pretty weird. If you do it in top/plan the wall splits along the cut line but the window moves itself over to be in one wall or the other. If you do it in a 3d view like top the window disappears entirely. I personally think this is a bug. Kevin Quote Link to comment
zoomer Posted September 11, 2015 Share Posted September 11, 2015 use the Ungroup command to separate them into individual extrudes. Thanks, didn't know that. (For Extrudes) But it is for Solid additions that you converted to Generic Solids, which I use most of the time. You can't even "delete" one of those extra volumes by Push Pull. You have to create a deleting geometry for a new Solid Substraction. Quote Link to comment
Kevin McAllister Posted September 11, 2015 Share Posted September 11, 2015 True enough. Those loose bits are a problem in Generic Solids. I don't understand why they don't break into separate pieces when they are converted... quite possibly a bug in itself. Kevin Quote Link to comment
zoomer Posted September 11, 2015 Share Posted September 11, 2015 (edited) Well, in my other CAD, for boolean additions, I simply select all "Walls" and run the tool. Those that intersect will glue together while everything else stays as is. So you can do all VW steps at one time. If you made something wrong in VW before converting to solids, you may have to move your dependent independent geometry later by push pull tool. :grin: Edited September 11, 2015 by zoomer Quote Link to comment

Kevin Hi Kevin The cutting line crosses the extruded shape. File attached. If I ungroup the extrude, then yes, it does split. Good tip. Thanks Brett Quote Link to comment
