This script helps create parallel viewports with specific vantage point characteristics.
There are two uses:
a) You can use this script to reverse engineer drawings printed with parallel views of unknown projection. You do this by
importing a background bitmap of the drawing in question. Draw two lines tracing the X and Y axis of that drawing and then
run the script with the ‘CustomPick’ option. You are basically telling Rhino: “Do you see these two lines I just drew in your Top
viewport ? Well, this is how I want the make2d result to look like. I want the 2d image to have that exact same projection. Give
me a viewport that will do this”
b) You can use this script to create standard Isometric, dimetric, Trimetric, or Custom angle viewports, by selecting the ‘Preset’
script option and manually entering the XY axis angles. (eg. 30, 30 for Isometric; 42, 7 for Dimetric, and 44, 15 for Trimetric)
