DEMto3D-QGIS-Plugin VS nscale4x8

https://github.com/jawensi/DEMto3D-QGIS-Plugin/issues/26 This is what you have to change to get the plugin to work. I'm doing to do some more work on my code this weekend to see if I can get it to run without needing QGIS at all. My tool is all in Python, but with a few tweaks I should be able to make it so you can give it an arbitrary list of LAS files instead of ones from the USGS website. I'll make a few more tweaks in the meantime, and you can give this edit to the plugin a try and see if that fixes your problem.

The original SketchUp models, STLs, and code are available for free at https://github.com/nscale4by8/nscale4x8/tree/master/buildingPatsInFlats. My GitHub account contains other free original STLs as well.

Here is a close-up of printed bricks. You would need to put your node on the structure so see this close: https://github.com/nscale4by8/nscale4x8/blob/master/buildingHyde/brickDetails.png

I made free downloadable STL files for both curved and straight bridge ties specifically designed to interoperate with Kato rails: https://github.com/nscale4by8/nscale4x8/tree/master/downloadableModels

Here are N-scale curved bridge ties as an example: https://github.com/nscale4by8/nscale4x8/blob/master/downloadableModels/bridgeTiesForKatoRails/R13.75B_p.stl
