jamesmise Posted March 6, 2018 Share Posted March 6, 2018 (edited) Hidden Line rendering is not displaying correctly in front or back views. Other views are correct. Attached are some samples and a VW file. Sample 1 shows what a front view, hidden line rendering should look like. I had to cant the model a small fraction to get it to render correctly. Sample 2 is a Front view, hidden line rendering and is showing lines that should be hidden, especially in the bottom center of the model. Sample 3 is an isometric view of the model. Any help is appreciated. I can't keep printing my drawings out and whiting out the incorrect lines.

Kevin McAllister Posted March 6, 2018 Share Posted March 6, 2018 I think this might be a bug with how container objects are rendered in hidden line. If I convert a copy of your symbol to a group and then ungroup it the objects draw correctly. If I regroup the objects, the problem reappears. It happens when rendering with hidden line in both the design layers and sheet layers. I would bug submit it. Kevin Quote Link to comment
jamesmise Posted March 6, 2018 Author Share Posted March 6, 2018 I tried what you said, but at first I did not also convert the sub-objects (the casters). It did not fix the problem. I tried it again and converted it to a group including the sub-objects and the rendering was correct. So it may have something to do with symbols contained within symbols. And as I said, the rendering was incorrect in front and back views only. Side views and isometric views were fine. I will submit it as a bug. Thanks for your help! Quote Link to comment
jamesmise Posted March 6, 2018 Author Share Posted March 6, 2018 One other note. I noticed that section viewports are not corrected after the process you described. I'm still working on a way for the section viewport to display correctly. Quote Link to comment

I played with it some more and have attached a fixed symbol version here. Not entirely sure what is causing it. It happens in all true views (eg. if I rotate the original symbol 90 degrees the problem shows up in the side views). For the fixed version I made 3 changes - I made a solid addition from the metal parts of the caster symbol. I made a new extrude for the back structure that extruded 3 of the parts together. I cut and pasted back the front deck piece. These simple changes seem to have solved it. Give this version a try and see if it does all you need. A VW mystery....

jamesmise Posted March 7, 2018 Author Share Posted March 7, 2018 Thanks Kevin. I believe the casters were pulled from the Sketchup 3D Warehouse. Maybe that has something to do with it. Quote Link to comment
markdd Posted March 11, 2018 Share Posted March 11, 2018 I took a look at the original symbol and there is a rogue single line in the symbol. Once deleted, it seems to work as normal. Mark Quote Link to comment
Kevin McAllister Posted March 11, 2018 Share Posted March 11, 2018 Interesting. I deleted the same line when I was editing it too. But if I edit the original and only delete the line it doesn't fix the problem on my install. What's even weirder is when I pan the drawing, the rendering adjusts to be correct but as soon as I release the mouse button it redraws as incorrect again. Kevin Quote Link to comment

Vectorworks, Inc Employee Luis M Ruiz Posted April 5, 2018 Vectorworks, Inc Employee Share Posted April 5, 2018 Here is my finding. When creating a section viewport the lines hide correctly. But you are correct, directly in design layer, a hidden line rendering does not look correct. Quote Link to comment
jamesmise Posted April 6, 2018 Author Share Posted April 6, 2018 @markdd seems to have found it. I've accidentally done this before myself. I guess every symbol you get from another source like 3d Warehouse, should be opened in a separate file in Vectorworks and thoroughly examined before adding it to a master drawing. Learned my lesson.
