GEOMETRY AND CAD / FIELD NOTE 09
Which CAD Files to Send for Curved Aluminum Panels
A PDF shows dimensions and notes while an editable surface file gives the fabricator geometry to inspect. A rendered picture is helpful for orientation but does not replace either.
What to check on your project
Agree on the native or neutral format and include the intended units, datum and revision. Reopen the exported file to check that trims, surface orientation and panel IDs survived the transfer. Attach a view showing the expected assembly.
