Point cloud / mesh to 2D drawing

I’m trying to make flat architectural drawings out of point cloud (or mesh) and I was wondering if there is an easier way than what I’m currently doing. I’m using PointCloud Contour, flattening the results and clean them to get the results I’m looking for. This method takes a lot of time so if someone knows a better, faster way to do this - I would be really grateful for any help or hints.

Below an example of my current work:

Since Grasshopper doesn’t have native support for pointclouds, is this a GH question?
