Could you share the LO file it is happening in? If not publicly, by private message?

I think if you are trying to duplicate what the Leica laser is doing, you would need to "replicate" what the laser does automatically.

The laser must be "fixed" in place and "shoots" let's say target #1on a wall, then pivot the laser tool (vert/horiz/etc) and shoot target #2 on same wall.
The laser takes both lengths recorded, and references the angle of pivot to report the "height" (if vert/assuming plumb wall)

You could easily do this in sketchup using a fixed point/protractor/tape measure tool, but the distance from the wall and the elevation of the laser tool must be known. (Assuming you are trying to replicate laser info)

You likely know all of the above and more, so I think to help answer your question more specifically, can you provide a simple example of what you are attempting? (Is this for something like photo match?)

Best regards,
Charlie

Does anyone know a good plugin for size and position of window opening for daylight.

You can take a look at Double Cut.

Also any plugins dealing with passive solar design would be great.

Extension Warehouse search word "solar."

try if installing the Windows runtime libraries required by SU v2016/2017 again helps:

• Microsoft .NET Framework v4.5.2+
• Microsoft Visual C++ Redist. 2015
• Microsoft Universal C Runtime Update f. Win 7/8.x

always run these installers (as well as the SU setup) by "r-click > Run as Admin".

Please ignore that last bit I am viewing this on my phone and just realised the lines have been added by yourself.

For me Save as component (once you've set it where it goes in the master model)works well. .. as noted above. Just be aware of anything you do with the axes for that component.
