Layout viewport revert to old version when scale altered

Hello.

I am using the latest version of Sketchup and Layout and am encountering problems (that I haven’t seen before) when changing the scale of a viewport.

I prep drawings with views in different scales to make the dimensioning as clear as possible.

I am aware that scenes in Sketchup need to be updated when changes are made to a model but this still is not rectifying this problem.

I can of course re send the model to Layout but this makes one of Layouts primary advantages redundant.

Any guidance would be much appreciated.

You need to add your layout file to get a full answer.

Post the file.

You may be referencing the wrong SKP file.

You may have altered the camera properties within layout and need to reset the viewport.

But until we see the file we can only guess.

Hi

Here are the Layout and Sketchup files.

Many thanks.

Picnic Table 001.skp (232.5 KB)

Picnic Table 001.layout (314.4 KB)

If you are working on ‘Picnic Table 001.skp’ you need to reference that in your LO file.

The LO file is referencing this file:

In LayOut go to Document Setup > References and relink the proper file:

Hi. I renamed the files to upload them. They are the correct files.

But then how are we supposed to test if it is working?

Is it not possible to link the layout file to the sketchup file?

I think you will see that the angled view of the 2 tables in Layout doesn’t match the ‘Angle’ scene in the Sketchup file? Oddly it just reverts to a previous view that doesn’t exist anymore.

Yes, but if you renamed things it is not possible to see what you setup before you sent it.

I’m really not understanding your problem.
I opened the SKP file and colored 2 boards.

I went to the Layout file and re-linked the file:

The board color was updated.

All of your viewports are at 1:25 scale.

What is not updating?

That is because you changed the camera position or some properties in the Layout view…

Push Reset All:

You can do change things in the LO viewport… but best to alter it in SKP, then re-fresh, until you are sure of what you are doing.

I suggested this in my first post.

I have reset all but I would like the angled view to be in a bigger scale. As soon as I chnage the scale it reverts to the old view. Do you mean that scale changes should not be done in Layout? It seems strange that that function is not advisable.

You are zooming the camera, not changing the scale. Scale is for 2d.

You can untick ‘preserve scale’ (which is confusing, but in 3d or perspective should be ‘preserve size’ or something similar), then make the viewport larger:

You can double click and zoom around - but be warned that this will alter the properties, and if you update the scene in SKP it will not update here until you press ‘reset all’:

If you have the scene set to Perspective in SketchUp, you can’t choose a scale in the Layout settings for that viewport. You need to zoom in and resize the viewport.

Simply changing the size of the viewport will change the size of the model on the page. There is no need to double click into the viewport to zoom in or out.

Leave Preserve Scale unchecked while sizing the viewport to adjust the size of the model on the page. Tick Preserve scale if there’s a need to adjust the size of the viewport without resizing the model.

Thank you bmike, levi and DaveR. I have been using Sketchup for a while now and have only bumped into this recently. It is great to get that sorted. I understand the logic now.

Good deal.

If you avoid overriding the scene Camera properties in LayOut you will have a much more predictable LayOut file. There should be no need to double click into viewports to zoom, orbit, or pan. Also no need to select a Standard View from that list and no need to manually tick the box for Ortho.

I notice some issues with your SketchUp model and have been in the process of reworking it to make it work better. Maybe you don’t care, though.
