Vectorworks, Inc Employee Stephan Moenninghoff Posted August 28, 2017 Vectorworks, Inc Employee Share Posted August 28, 2017 (edited) Is there some way to do this? Just like I would if I had extracted the NURBS surface with "Create Planar Objects" given as an option? Can't seem to do this with any of the stock nodes although it should, in theory, be possible..

Vectorworks, Inc Employee Stephan Moenninghoff Posted August 29, 2017 Author Vectorworks, Inc Employee Share Posted August 29, 2017 The nearest I got was "Convert to Polygon" but that fails if the NURBS Surface is fully clipped. It seems to work OK with partially clipped NURBS surfaces. I guess that's worth a bug report... Quote Link to comment
the frog Posted August 30, 2017 Share Posted August 30, 2017 hello Maybe it’s because of the bug inside the covert to poly node see convert to polygon doesn't work in marionette object Quote Link to comment

BTW it looks like the forum is breaking the links when copying and pasting. Your hyperlink comes up dead. Quote Link to comment
jeandm Posted September 8, 2017 Share Posted September 8, 2017 Hey, It's dirty but it works if you input enough accuracy... For some reason it says that it returns as many POLYs as the number of vertices, but in the group there is only one... Go figure NURBS TO 2D POLY.vwx Quote Link to comment

What you are converting is a NUBS *curve*. In my example, I'm trying to convert a NURBS *surface* to polygon/polyline. I tried your node and it yields no result for a NURBS surface. I guess we'll have to wait for an official way to do this... Quote Link to comment
jeandm Posted September 8, 2017 Share Posted September 8, 2017 I see, I misinterpreted your intention! I'll do some more digging. Quote Link to comment

I'll do some more digging. OK, good luck! I think what we need is the "Extract 3D" tool's function with planar set as an option but there seems to be no node doing that. I have no idea if this could be scripted by hand. Edited September 8, 2017 by Stephan Moenninghoff 1 Quote Link to comment

I don't think there is a function available to us in python to do a surface extraction at this time, so I don't think we can pull this one off until it gets exposed to us. 1 Quote Link to comment
EParks Posted September 12, 2017 Share Posted September 12, 2017 Having recently been delving into Marionette more, I too have discovered that a node for the "Extract 3D" would be extremely useful. Although my confidence in editing existing nodes is growing, I am not yet at the point of creating new nodes from scratch. One of the tasks I am aiming to automate is the extraction of areas from 3D wireframe models and then labelling and scheduling these in a worksheet. The ideal work flow for the as yet un-created tool would be: Extract all faces from selected (simple) 3D model. Rotate all to be on same plane. (This step could be skipped if something like an ID label could be applied to the faces of the model) Apply a pre-determined label (from a symbol - as is possible in the Space Tool) Schedule the areas in a worksheet. I think I could just about manage steps 2 and 4, though no 1 is non-existent and although label creation nodes appear to exist, I'm not sure how to "fix" them to a 3D surface. Any thoughts or ideas welcome. Thanks. Quote Link to comment
