PreView

[sevenoffline]

The handling is a bit akward because of the different projections. If I want to have a 3x3 tiled squared model I first have to output it untiled to check if the wanted area is correct. I have to do this several times because there are two stages of "blindness": first the selected area has a different ratio on the map-screen then on the object, second the squared-mode alters the selection. When this procedure is finally done I can switch to 3x3 and output the final model.
This workflow is soooo annoying!
Isn't there a way to create a kind of preview? Some outlines on the screen-map to see the resulting ratio & area would be most helpful. I know about the different projections but there has to be a way to calculate this beforehand.
A model-viewer to see the computed model in low-res would be great but I guess a lot of users would mistake the low-res-preview for the final model.

This sounds like a good idea in general.

A preview (which includes the 3d elevation shape) would also require to download the GeoTIFFs, which usually contributes a significant amount of time to the overall STL computation. Thus generating a preview would require a similar amount of time as the STL file computation.

But I like the idea and will have a closer look into what it would need to implement this. But don't expect something any time soon.
