it works! 
I am still studying your code to understand more
what did you do?
u r trying to convert the solid ToProtoType()
if fail, then try to find the faces, and form a solid by all the faces
if fail, then try to find the edges from faces? am I correct? and then form faces by those edges, and then form solid from those faces. (edge to face, face to solid)
thank you so much
P.S. revitapi is so complicated, too many classes, methods…
yes exactly
I’m not sure that I have a solution for this…
try to change the geometry scale or use the @chuongmep 's solution
I would use @c.poupin’s or @chuongmep’s code! My attempt was very amateur

Please notice that you need to scale up 1000 times the geometry to get the correct scale (metric), otherwise it is not in correct location
