I am new for revit, I still confuse how to create reference line. Do you have video including create all reference lines from start step? Sorry I never do form befor,
Hi, I try to study making curved form, use reference line for horizontal and reference spline for curve, but form doesn't follow the point to make curve, please tell why? see Attached picture.
Yes, that exercise may not be appropriate for your level of experience. You asked the question, and I provided the link, but I did not know more information about you being new to Revit. I cannot determine why it is not workfing for you since I don't know what steps you took or what steps you missed.
The video explains clearly that some edges need to be "lines" and some edges need to be "splines". You did everything with "lines".
