What Draw Ventilator does
Draw Ventilator places wall ventilators near the ceiling using the same opening pipeline as windows and doors. It supports planar and curved walls, includes optional chejja sun shades, and can generate UPVC ventilator assemblies with adjustable louvers and exhaust holes.

Chejja / Chajja sun shade
Enable Include Chejja to add a projecting sun shade above the ventilator. Choose a flat, sloped, L-type, or box profile, then set the projection and thickness. The chejja is generated as separate geometry on the appropriate layer.
