  1. I have a 3D object with planar faces that I'm trying to draw on the surface of. I used the Set Working Plane tool in Planar Face Mode. It highlights when I mouse over it, I click it, and the pink square shows that the working plane is now aligned with the planar face. Except, it's *almost* aligned with the face. It's actually slightly off. This is evident when I move my mouse around over the face, and I can watch edges of the preview "square" disappear under the face. When I try to draw lines on the face (after using the "Look At Working Plane") command, the lines start out above the face of the object, and then as I stretch the line across them, they disappear underneath. When I rotate the camera around, the lines are hanging out in mid-air, hovering above the object. This planar face that I'm trying to draw on is not at any 90º angle to the ground - ones that are don't exhibit this issue. It's odd that it sets the working plane to be close, but not quite correctly. This...this has to be unintended, right? Or am I just Doing It Wrong? [Edit] When said planar faces turn blue, they also (upon camera rotation) exhibit Z-fighting artifacts. Resolved: Good grief, the face was not, despite my best efforts, actually planar. I didn't realize that was possible with how I constructed the geometry. Live and learn, I suppose.
  2. Hello. I'm trying to do two things. One is create a seamless NURBS surface, which is apparently very difficult to do with the shape I'm working with. I have two NURBS lines, which I can create a loft surface with, but the loft surface command breaks the surface it creates into multiple (in this case eight) pieces. After much searching, I've learned there is (apparently) no way to combine NURBS surfaces into a single surface. Is there a way I could create this shape as a single NURBS surface? Or use some little-known trick to combine them? Specifically NURBS because I'd like to use the surface array tool to, well, create a surface array. Which brings me to my next question: messing around, I created a surface array with the leaf shape shown here, but VW turned my surface object all helter-skelter in space, and then I had to rotate and put it back into position. Clearly the program can figure out how to apply the surface object the way I want. Why does it need to move the surface object around to do it?
  3. I'm having a very weird issue. Several weeks ago I was having an issue where objects that I would make would randomly vanish, so, silly me, I kept copy-pasting the object from another file. Annoyed, I finally just re-made the object (in this case, it's an extruded bit of geometry.) Fast forward a few months, and I'm finally putting together my sheet layers and putting viewports on them. Lo and behold, all the objects that I thought were gone are there, in the viewport, all clustered up together where I left them. They are in the "None" class, which I know because if I set the viewport not to show the "None" class, they vanish. Problem is, I cannot find them *anywhere* in the design layers. Both layers and classes are set to "Show/snap/modify others", and the None class is editable and has both a fill and a pen color. How can something be visible in a viewport but not in the design layers?
  4. I'd like to jump in and confirm I am also having this issue, the symbols vanish and it takes some undo / redo voodoo to get them to come back. Screenshots at: https://imgur.com/a/hO2t9
