Same edge styles, some won't display in layout

In vector rendering, some edges are displaying and some aren’t though the geometry is the same as far as I can tell. Any thoughts as to what I am doing wrong? I would prefer not to use raster as that adds a different group of problems.

Thanks for any input.

One thing to check would be the distance of your model from the origin point. The longer the distance, the more inaccurate the calculations. The algorithms that calculate the visibility of edges have a limited accuracy, otherwise they would take an infinitely long time to complete. I first met the problem of lines that should be hidden showing and those that should be visible getting hidden more than 30 years ago when creating my first 3D visuals in AutoCad.

Open this in LayOut and see if it looks like what you are hoping for.

Dave, that is what I was hoping for. What did you do?

I unsoftened the edge immediately behind the front vertical edge. I think what is happening is a graphics issue where the softened edge is so close to the front edge that the two aren’t being displayed at the same time and the softened edge is “winning”. Another, probably better way to deal with this would be to change the arc for the profile. Either use fewer segments or slightly change the radius of the cove. Make it a little larger radius. Here I’ve drawn in a new arc, in blue.

It may not exactly represent the profile but then again, the arc you drew doesn’t, either, because of the facets. No one will be able to tell it’s not the same.

Amazing! I never would have discovered this solution considering the problem was only occurring on random edges. I’ve been struggling with this issue for a long time, luckily on this project I finally invested the time into starting to learn Dynamic Components so the fix won’t be too painful. I can’t thank you enough for your help!
