You first have to understand that in AutoCAD there are three types of polylines, a 3D-Polyline, a 2D-Polyline and a LW-Polyline (or just polyline). So, is there anything I'm missing or doing wrong or is there anything else I can try? I have attached the offending drawing in case someone can look at it. That's not a LINE or POLYLINE, it's a LWPOLYLINE Again, I converted the polyline before more attempts. I tried a couple of more times with both smaller and larger values but got the same result.

This made no difference whatsoever, so I relaunched ACAD and tried the 'weed' LISP. I tried converting the polyline then tried the command again. I have no idea why it 'treated 22 polylines when I only tried 1, without success. Simp-Pline loaded, type SPL to launch the function. There are a couple of LISP routines on that thread, 'weed.lsp' and another 'purge-pline' found here (linked by Lee Mac). I searched 'de-densify' and 'densify' and the only topic I found was this one: Link which I don't think is the one you were referring too.

There was also a LISP routine that someone suggested. I think ReMark had some useful advice on the matter. Need to figure out how to take the location of complicated models on site & represent the location in side plant - currently the location can be set by the imported xref.Ĭollision checking then performed in Navisworks.Do a search on de-densify, there has been a thread on that recently. Currently the plant dwg is big - looks good in Navisworks but sluggish inside plant. Presume the revit/inventor models are sent to Navisworks & the Plant Model sent to navis too, thinking about how the co ordinate systems are all tied together. Are imported models best avoided because of the performance hit?

this looks like a way to keep everything a simple as possible. The tutorials I've seen appear to point to creating models from scratch using the tools within plant. With Inventor a sketch plane can be used & geometry projected & extruded - not sure how to keep the same co-ordinate system trying to copy the workflow in Autocad. Models imported from Inventor & Navisworks can be sizable - currently theses models are xrefs but when switched on performance is slow.Īny top tips for creating simple representations of imported model for plant 3d
