Scale 2-Point Persepctive?
-
Anyone have any thoughts or tips in bringing in a two-point perspective section cut scene from SU into LO, and have layout make it read at correct scale?
I know that being in perspective mode makes scaling not really work, but in theory, this could/should be done.
Meaning, the section cut itself, ignoring anything beyond, is technically in parallel projection, and really its a flat 2D cut and could/should be scale-able. But then the "beyond" portions are simply projected off of the cut, and obviously would not be to scale.
Any help or thoughts would be appreciated, thanks!
I've attached a quick image from SU of what i would like to show, just need to have LO produce the section cut to scale.

Eneroth has a plugin for just that.
What I do is that I have 2 scenes. One with the perspective and a copy where I see only a section cut face group.
I place the section cut group viewport at the correct scale in layout, wich is easy as it's a 2D model, then you you copy that viewport and replace the scene in the model for the scene of the perspective.
This way I get double viewports and can manipulate the section face scene independently of the perspective scene (wich is exactly what I do on ortho sections too).

It's not for layout and I never used it, but it's a plugin that enables you to scale your perspective view in relationship to your screen resolution so you can translate it to Layout with a give scale.
I understood what was the purpose but, again, I never used it, so it might work in another way...

Thanks! Eneroth is a genius!

Thanks for the heads up! I should have known there was a plug-in by Eneroth, she has a plug-in for everything!
Was a little awkward to use at first, but once i got the gist of it, worked perfect. Was able to use scaled dimensions in LO and they read the exact heights they were suppose to!

The Eneroth plugin worked great, but i am curious about your 2-viewport method. Can you elaborate a little more on this process? Or potentially have files to share showing the scenes in SU and viewports in LO?

You don't even need 2 viewports, I use them always though and I'm used to setting things up on sectioncutface viewport. So in LO you can:
- Insert a perspective viewport;
- Draw a line on the section through two points wich you know the dimension;
- Scale it so it fits the desired dimension;
- Write down the resulting scale factor;
- Scale your viewport to the same scale factor;
- Lock viewport scale;
- Stretch it's boundaries to focus or have a wider view of the model.

Awesome, thanks for the quick reply. In actuality, you are doing the exact same thing that the plugin you referred me to does, just a different path to get there.
Totally makes sense, thanks again!

Then I remember why I'm not using it... She won't mind, I use a couple of her plugins daily...
