From Blender you can upload a background and with a curve you can use "duplicate from curve plugin" for design your track. You can use also the GIS plugin:
You can import a path and a house... After that it is easy to reproduce a house with LFS objects for example.
The finished layout doesn't match what I see in Blender
Hi Vritrasura and NENE87,
Hope you’re both doing well! I wanted to start by saying a huge thank you for your work.
However, I just encountered a minor problem, and I'm hoping you might offer some advice. The finished layout doesn't match what I see in Blender when I use wall models in Blender and export them for usage in LFS.
This might help in your specific case, but may break other blocks. because if equation was wrong it would be wrong for all blocks. What I think is that i have models wrongly oriented. if you rotate them in edit mode that should fix them. I will have to revisit all blocks and check that their orientation is correct. Will try to do it this weekend.
