How can I import an spc file through Composite/Composite-General/Import SEC Files? I encountered an issue where only 1 unrelated section is listed in the Section List when SEC file is selected. Clicking OK results in a warning about a problem in generating a mesh. Can you help me resolve this issue?

Answer:
Actually these types of issues arise when the sections are too far from the origin location ( ). This leads to tolerance issues. Hence, it is recommended to move the curves near the origin before calculating their properties or exporting them.
I've done that in the attached SPC file. However, the sections would have to be redefined with appropriate properties. I've checked for one section as a check and its working as expected now.
