Revit does not know why there is a strange rule that it is impossible to draw a line of length less than 0.8mm in length. (0.8mm equals 32 of one inch). Cause a lot of small short lines cannot be drawn.In light steel thin-walled member, its thickness is only 0.5, some 0.7, can not be drawn. This brings some limitations to Revit's work.Here is a programmatic way to create less than 0.8mm, and its usage is a bit hard to think of.First we create a long l
