Layout Scale Change "Target"



Good morning!

I’m very curious as to how I can anticipate where a part of my model will end up when I change scale?

For instance, if I am trying to target a door in an elevation that I have at 1/4" scale in that viewport, but I need it in 1/2" scale, often what happens is my drawing and the target will run well off the viewport.

Is there any way to target that door so that a scale change ensures that it’s in the center of the viewport? I’m tearing my hair out on this. Would help speed up my work tremendously.

Thank you all!


Are you using scenes in SketchUp to create the views of your model that you need to show? And are you making sure they are not getting modified in LayOut. (as shown in the Scenes list.)?


Yes. Pretty standard scenes. Groundplan, Elevations as necessary. ISO.

I set my scenes up as Zooming to Extents. It lets me use the same scene for details. The issue is that when I rescale the viewport for a detail (say 1/4" to 1" or FS) I spend too much time trying to find the detail! Hopefully that makes sense.


OK. So you have your scenes established in SketchUp. Are you opening the viewport to zoom the camera when you get to LayOut?


Not zooming the camera (you mean double-clicking to access the model within Layout, correct?). I’m merely changing the scale.


Yeah. That’s what I meant. It’s good that you aren’t double clicking in the viewport. I understand now what you are getting and why. If you need to do this frequently, and it sounds like you must if it is consuming a lot of time, I would make two suggestions.

The best option would be to create scenes that show the specific details. So zoom in on the door and make a scene for that in SketchUp. Then use that scene for the viewport.

I’ll guess your response is that it’s time consuming to make those additional scenes. I would guess it takes less time to select a door in SketchUp, use Zoom Selection to bring it to the center of the screen and create a scene that it takes to fix the viewports in LO. :slight_smile:

The other option would be to drag the sides of the viewport out before changing the scale so you have a larger area to look at and you’re more likely to see the detail you want. The problem with this besides the time it takes is that you then have to adjust the size of the viewport and move it where you want it.


Seems like the only answer is the one I’ve been doing and didn’t want. Haha.

I suppose creating the extra scene is the way to go - though I worry sometimes if I move the model while making changes that I’ll be back to the drawing board (ha) trying to find it.

Dragging out has been what I’ve been doing - was hoping there was something more intuitive for laying out “on-the-fly” - in the same way we can target zooms and rotations in our models - perhaps with the precision cursor.

Thanks for responding - even though I wish there was a magic trick.


If you’re moving your model in SketchUp after you create your scenes, you’d still need to update the scenes, right?

For most of the stuff I do in LayOut, I much prefer to make scenes for each specific view I’ll need in LO. with the detail I’m interested in always in the center of the modeling window for the scene, it makes it much easier to figure out resizing. I can just resize the viewport about its center as needed. No need to go hunting for the detail.


Forgive me if I just haven’t noticed - maybe you have some insight. When you DO re-scale in layout - what does LO consider the center point? The origin in the model? Somewhere else? I haven’t picked up on WHERE it chooses to expand from.


It’s the middle of the scene stays fixed and everything gets resized away from it. Obviously in your case, the middle of the scene and the middle of the viewport aren’t in the same place.

Edit: I just checked to confirm it. The center of the scene in SU stays fixed when the viewport is resized even if the viewport is not centered on the scene.


Ah! Mystery Solved. Thank you for that. And all the help!
