Not printing to scale. t 4m, even though the scale

[edward139]

Not printing to scale. Drawing in a scale of 1:50 however, when printing a line scaled 3.5m is printing out at 4m, even though the scale in PDF is still showing 3.5m. Any ideas how to fix this problem?

Hard to tell with so little information. Are you printing directly from SketchUp? Do you have the Camera set to Parallel Projection? Do you have a standard view set up for the scene? Do you get the same result if you use LayOut? Can you share the .skp file so we can see what you actually have set up?

Thanks for the quick reply Dave. The drawing in in the model set up and then I export it to LayOut, set the scale to 1:50. check the measurements and print. There is about 10% discrepancy increase when printed.

Can you share the .skp or better, the LO file so we can see what you have set up?

OK. So you have the camera set to Perspective in the Sketchup model, not Parallel Projection as I indicated you need in my first reply.

You haven’t set up a scene in SketchUp so you are using the Last saved SketchUp view which is going to cause you trouble later. Since you have the camera set to Perspective you cannot set a scale for the view. Note that Scale is grayed out in the sketchUp Model panel.

Here I’ve set up a scene with the camera set to Parallel Projection and the Left elevation view.

In LayOut I chose the Left elevation scene and could then select the scale of 1:50.

Here’s the resulting PDF. Print that and see how you go.

You wrote 1:50 for the scale in your first post which is what I set. There’s text indicating it’s 1:20 in the LO doc but at 1:20 it won’t fit on the paper size you selected.

A couple of notes on your model:

1. It’s a good idea to keep faces correctly oriented. You have a lot of exposed blew back faces.
2. Don’t apply materials before fixing face orientations. That just masks problems.
3. You should be using groups and components. You have a lot of loose geometry which will make your model more difficult to work with.
   
   
4. Purge unused stuff from your models periodically. This reduced the SketchUp file size by nearly 72% and reduced the LayOut file size by about 52%.

Here I’ve revised your LO file to show the elevation at 1:20 on A3 paper. I removed the dimensions for the Sketchup model and added them in LayOut. I notice that you used a Scaled Drawing when you created the text on the page. There’s really no point in doing that because the text doesn’t need to be a Scaled drawing and that has no impact on the Sketchup viewport either.

Thanks Dave, for your time and comments. they are very helpful and allowed me to move on another step forward. I also taken onboard your other comments.
