Poor quality pattern rendering in LayOut

Hi,

I am trying to set up Curic Section with layout to produce section drawings that will be between 1/2" = 12" and 1"=12" scales and I’m experiencing issues with render quality.

This what it looks like in SketchUp:


Crisp. Clean. Congruent with the image quality one might expect from $350/year/seat 3D modeling software.

This is what it looks like in the LayOut work space at 3/4" scale. Single hybrid viewport with 0.10pt 1x line scale and high render settings.


This is what it looks like in a PDF export:


Looks like pure unadulterated ass.

I understand that I’m zooming pretty far in on this but is that really the best I can hope for in terms of a raster image render?

I’m happy to share the file but there are definitely not best modeling practices being followed in it. It’s a sandbox that I’m using to dial in curic section.

What are your export settings? Firstly LO previews at a lower quality so don’t worry too much what you see in the LO viewport/canvas. By default LO renders I think at medium image resolution. Might not be a drastic improvement but worth looking into.


The only way that I can think of to improve on this is to scale the layout paper space by 2x and export it at half scale. It just doesn’t want to render raster images at higher than like 50 DPI unless I’m missing something.

Hmmm…What’s the source and resolution of the original wood texture you’re using? Edit I see it’s happening to all of your textures. Can you share the full PDF export, not a screen shot?

I think LO is operating normally. It’s a very small detail you’re showing so it’s technically viewing fine when displayed at ‘actual size’. To see that pixelation, you need to zoom in 800% - which is unreasonable to expect a raster image to maintain its resolution at that level of zoom.

Here those textures display normally at a higher res:

Thanks Eric. You’re right. It’s zoomed too far in.

Making me wonder if it’s even worth bothering with material hatches at this scale. Even printing at 1:12 its pretty small.

The “High” resolution export from LayOut is 300 DPI, so assuming your boards are about one inch thick, there is room for about 25 pixels at 1:12 scale. Printing to paper makes it even worse if you aren’t using dye-sublimation, as printers use dithering to create colours so the practical resolution is still more coarse.
