Some strange things are happening with the construction of Material Appearance Assets. I am trying to write a JPG onto a surface in Rhino, much like the _PictureFrame command in Rhino.
Is there a clue about why I need to scale my Bitmap Asset to approximate the correct scale in Revit?
In this screen shot, the final Offset and Scale dimensions for this Cutout Texture should be -0.90m & 1.8m; this matches my input (see the panel titled Actual Panel Size).
–On the right, the grasshopper side, you can see that I had to scale the input by a factor of 40 to generate a sample size of 1.83m, not quite the 1.8m I require but close enough to illustrate this question. Units in both Revit and Rhino are Meters.
If the scale were related to the actual dimensions of the input image, the first example scale would a factor of 1 (not ~40 because the actual dimensions of my JPG for the cutout textures are 1.8m Width x 0.45m Height).
So the Metric template I am using is in mm. And the Bitmap Asset size is still in inches. So, to specify the correct size in mm I set a conversion factor on the Height and Width:
