Control display of folding lines on toposolids

spm8C88E — Mon, 13 Nov 2023 10:16:53 GMT

I started using the new toposolids and looking for a way to control the display of the folding lines. I don't want to see them, but turning them off results in a white line in the plot, see image 1. I can change the folding lines to match the color of only 1 of the toposolids (see image 2) but there doesn't seem to be a way to effectively hide these lines if you have 2 colored toposolids in the same view. I tried filters, override by element, any other suggestions? there is no transparency setting for these lines....

I can't reproduce. Makes me think that maybe your printer is the culprit.

Somehow the lines don't look as bad today....Anyway I only have Adobe PDF and other standard Microsoft pdf printers (none of the MS printers allow me to select A1 paper size or create a custom paper size). I was able to make the lines go away using the Adobe PDF set to raster plot, however I'd prefer to use the vector plot setting. Can you share what settings or printer you use or what about the printer affects this?

Share your file. Let's see what result I get. Maybe there's something else going on in your Project.

There are 2 sheets in the file, the issue appears most noticeable on the takplan (roof plan), perhaps because the planting on the roof is represented with a darker green.

While you have the file another issue I'm running into with the toposolids is a constant error "Can't cut joined element" when trying to join two adjacent toposolids of the same type. I can't find a solution to this. Some of the toposolids are cut with vertical openings but that doesn't seem to be the issue.

We see the same. Tested on a new project, new toposolid, hidden line plan view. Occurs with any vector PDF generated with built-in PDF exporter, Acrobat and Bluebeam.

White lines in the pdf are really just gaps between each triangle and not actual lines. I see this applies to modified floors as well. Unfortunately, even though the view is orthographic and there is no shading, each face/triangle gets processed separately and not unified together as a single shape/path.

I'm guessing this behaviour has been around for years.

Hate to bring up an old thread, but we have the same issue now as well. Would love if this could be addressed...

Any solution found for this yet ?

@bknittle that will not solve the OP's problem which occurs on a Hidden Line floor plan where the material surface patterns generate the colours rather than shading.
