Nothing draws at all. The series has no X-section setup: confirm the Unit Part exists
and its rules (level/position) match the node you expect the section on — frame vs sash vs
mullion is the usual mismatch.
The part has artwork but still nothing draws. Check the image is SVG — DXF is
stored but never painted on the canvas. Also check the part’s description is exactly the
image filename/path.
The section draws in the wrong place. Adjust the ΔX/ΔY rules (301–318 range) and make
sure they sit before the 319/320 placement rule in rule order; a transform rule after the
placement rule is silently ignored for that section.
The artwork is rotated or mirrored wrong. Expected — rotate/flip are recorded but not
applied at render time. Replace the image with pre-oriented artwork.
Glass is missing from the section. The opening is unglazed, or there is no glass-level
rule for this position.
Pressing × “deleted” my sections. It only hides them — press V or H to bring them
back. Sections are only truly discarded with the design itself.
