New update is out, hope you're enjoying the fast release pace. We'd love to hear your feedback.

Sharper opening snaps and steadier arched frames
Placing openings now snaps cleanly to existing edges and walls, including geometry nested inside groups and components, so doors and windows line up on the first click. Semicircle frames are more stable, and louvers gain sensible limits.

Openings snap to existing edges and wall segments while you place or move them
Snapping now reaches geometry nested inside groups and components
Semicircle frame-and-glass openings build with a cleaner, more stable seam
Louver slat count capped at 32 to keep the model responsive
Clear on-screen hints for louver slat limits and the -89° to 89° tilt range
Openings that land where you mean
Placing a door or window is now a snapping experience. As you move an opening along a wall, MUZWalls picks up the edges and segments of geometry already in your model and pulls the opening to them — so a new window aligns to the head of the one beside it, or a door squares up to a return wall, without nudging by eye.

Crucially, this now works through groups and components. Earlier, snapping only saw loose edges in the active context; if the geometry you wanted to align to lived inside a group — as most real models are organised — it was invisible to the tool. The snap engine now looks inside nested groups and components and transforms their edges into place, so the points you actually want to hit are the points you can snap to. Snapping stays responsive by favouring the candidates nearest your cursor.

Steadier semicircle frames
Arched openings with a frame-and-glass infill have been stabilised. The curved frame profile and the seam where it meets the glass panel now build consistently, smoothing out the small geometry glitches that could appear along the arc on semicircle openings.

Sensible louver limits
Louvers now cap at 32 slats. Very high slat counts could push SketchUp's geometry engine hard enough to become unstable, so the count is bounded — with an on-screen note explaining the limit. The louver tilt field also shows its valid range up front: any angle from -89° to 89°.

How to update
In SketchUp, open Extensions → Extension Manager, uninstall the previous MUZWalls, and install the new .rbz from the download page. Your existing license activation carries over.
