Edges in LayOut different to SketchUp

Join 1 - LayOut

Anyone know why the edges are warping in LayOut? As always, in the middle of a project with the client anxious.

Which one is which? Can you include the Layout File so we can see? Are you using SketchUp Layout 21? What is the viewport rendering set to, Vector, Raster,Hybrid. Is there any style override in the sketchup model pallet of Layout? is the camera set to a standard scene or a saved SketchUp scene? Need more info,

They were labeled, but that doeasn’t display - the top is the LayOut.
I can’t share the file.
Hybrid, and nothing fancy in styles.
Standard Scenes from SU
Everything is grouped

The error occurs in Hybrid and Vector - but not in Raster.
But although it looks fine on the screen, the error shows when a PDF is produced.

How far is that part of the model from the origin?

600 mm

What’s the overall extent of your model?

It’s not large - around 4m x 2m x 1.2m

The parts are small, but not miniscule - the horizontal green and purple are 2.1mm thick.
I reduced the line thickness, and this image (Vector) shows that every join has jumped, and also that the yellow fill is bleeding.
A serious debacle - as this is for approval to go to toolmakers today.

I’m guessing it is too small. Scale it up by 100 or 1000 and see what happens.

It was already scaled up x10 - to show the client detail.
I scaled it up by 100 in LayOut just to see what would happen and there was no difference.
Any bigger than x10 and it won’t fit on an A3 page in any case.
Remember, this is LayOut, not SU.

Thanks for the inspiration.
I scaled the model in SU up x100, exported it to LayOut and then scaled it down x100.
Displayed in Vector, this seems to have eliminated the distorting lines, but the colour yellow is still bleeding into the gap with the adjacent part. (It’s a mess in Hybrid.)

I tried a few ways to reproduce the error but cannot, without seeing the file it’s hard to guess at. Have you tried different settings on the output options for .pdf, higher quality, but it should not matter. It does look like a graphic artifact from a very far from origin or large model problem, but I have not seen that in Layout. Or an off angle camera but it sounds like it might be a small geometry issue? Can you export that page as jpg or png without error and convert it to PDF after as a workaround, or is it bad in vector in any format?

I tried exporting an image and also taking a screen shot, but the resolution of the jpg image is very poor.
The purpose of this particular image is to show the gap tolerances (.1mm) and flush points, and so it needs to have clearly defined edges, and include dimensions.
The wierdest thing is that the line distortion occurs at the perimeters of the scenes where there is no connection to any other parts also. This is not noticable at normal scale, and I suspect it actually has happened other wise but gone undetected…

How are you ‘scaling it down’ in LO? Are you just changing the scale with the dimension tool or are you doing something else?

.1mm is really small… if you scale this up x100 in SU it turns into 10mm but if you then have to fit it on a small sheet I can see LO having issues with it.

What scale are you using to display this in LO?

A 1pt stroked line is approximately .35mm - so even at 1 to 1 scale you will have issues showing this properly.

Regarding the color bleed - I am assuming all of your shapes are groups / components? What happens if you use hidden line style then render in vector, explode the viewport in LO and manually color the shapes?

I simply set the camera scale for that scene portal at 1:100.
Displaying the lines is not the issue - the distortion is the problem - except if I do the scale jugling thing. I would have thought a 1pt line will print as a 1pt line no mater what.
All parts are components.
Not sure about the exploding thing, as when I attempt to add any shapes the portal unexplodes.
Manually colouring the shapes will be problematic in any case, I know that from experience - things simply don’t line up, and there are a gazillion corners of different shapes in this.

Yes, in LayOut if you have your line weight set to 1pt it should print 1 pt which is .35mm which is larger than your tolerance of .1mm. So if there are 2 lines (1 for each part) and in your model they are .1mm apart but the line thickness of 1pt (.35mm) the two lines overlap each other, this + the likely very small faces for the curves could be causing issues with the fill.

What happens if you set the viewport to 1:1 scale or 2:1 scale and adjust the view to see that part of the drawing (disregarding dimensions for the moment)?

Had to move on - so have used hidden line without colour at 1:20 scale, and manually adjusted the dimensions.
Except for the perspective views, the rest of the document is 1:1. The issue is present in every scene, but not noticeable as it they are relatively small, so as long as the client doesn’t zoom in on the pdf or look closely if they print it, everything is good. The critical thing apart from providing the detailed information on tolerances, which is what this is all about, is that individual parts export properly as dwg, for the tools to be machined.
Thanks for trying.
Certain things, like this, which are straight forward for cad, make for wasting enormous amounts of time, and cost money!

The game continues - but now it is serious!
The first image show what happens when the file is sent to layout at 1:1.
I found that I can recreate the model in LayOut by scaling up in SU and then reverse the scale in LO.
This looks fine - image 2, but the dwg file exports from LayOut at the original SU drawing scale (x10) - no matter what I do.
I am pretty fed up with spending hours trying to figure out something that shouldn’t need to be figured out.
Anyone have any clues about scaling a dwg export from LayOut.
