Polyline, circle and line as 3D entities in General Discussion Posted March 10, 2016 · Edited March 10, 2016 by P Retondo Must be a 2016 thing. In all previous versions, a dialog box comes up when creating a symbol with a check box asking if you want to change all layer plane objects to screen plane. For those who aren't aware, the original VW (MiniCAD) and in versions of VW up through a few years ago, there was no "screen plane" / "layer plane" dichotomy. In fact, every 2d object was what we now call a "screen plane" object, and anyone who has the experience indicated by some signatures on this thread has long experience with using screen plane objects, even if they didn't know that's what they were! This was historically a big difference between VW and AutoCAD, where all 2d objects were actually 3d - basically, what we call "layer plane" in VW. I use virtually nothing but screen plane objects, even though I do a ton of work in 3d. I find it incredibly useful - think of it as a layer of trace on your screen, where you can draw and think in 2d with respect to the view on the screen. I actually think it was a mistake to embark on this "layer plane" notion, instead of enhancing the 3d objects we already had. But this is the VW we have - it would help if certain operations did not inadvertently toggle the preference for screen vs. layer plane. Every time I edit a sheet layer viewport crop, my "screen plane only" option switches to "working plane only," and I have to switch it back (this is 2015). Hopefully this bug is fixed in 2016, I'm just starting to use the new version. For anyone who doesn't know, you can choose "screen plane only", "working plane only," or "screen plane or working plane" in VW preferences / plane mode tab. PS: if you want to make sure moving a 3d object in a 3d view does not change location with respect to the screen normal axis, just draw a screen plane rectangle between the points you want, set it to the side, and between the corners of the rectangle. Just one of many useful screen plane object tricks.
