Walls + mitering in 3D
Diaz miters wall corners automatically based on thickness and angle. T-joints follow a priority rule. Acute corners under 15° need a manual review.
Quick answer
Toolbar → Wall. Click corners — Diaz miters automatically.- Right-click a corner → Mitering override to set a custom angle.
- T-joints: the thicker wall wins by default. Override in the inspector.
Step-by-step
- Open the wall tool:
Toolbar → Wall. Set thickness in the inspector before drawing (it locks in once you start the first segment). For a typical residential project: 220 mm exterior cavity wall, 100 mm interior partition. - Click corners in sequence along the perimeter. Diaz draws each segment between clicks and auto-miters the corner. A standard 90° corner gets a clean 45° miter on each wall end. Other angles get half the corner angle as the miter on each side.
- T-joints (a wall meeting another in the middle): Diaz applies the "thicker wins" rule by default — the thicker wall stays straight through, the thinner one butts against it. To override, select the T-joint and use the inspector: Through sets the wall to pass through; Butt sets it to stop.
- Custom mitering angle: right-click a corner → Mitering override. Type the miter angle for each side independently (e.g. 30° on side A and 60° on side B). Useful when one side has tile reveal or trim that needs a different cut than the other.
- Wall ends (free, not at a corner): set end-type in the inspector — Square (perpendicular cap), Rounded (180° half-circle), or Slanted (45° taper). Square is the default for most internal walls; slanted suits a half-height wall ending in open space.
- Inspect mitering quality after import: imported DXF walls sometimes have tiny gaps at corners that prevent auto-miter. Use
Tools → Clean wall joinsto merge corner endpoints within a 5 mm tolerance and trigger mitering.
Watch out
- Acute corners <15°: auto-miter produces a sliver-thin corner that is impossible to build in masonry or drywall. Diaz flags corners below 15° with a yellow warning — review and round off the corner or rework the wall layout.
- T-joint priority mismatch: if you expect the thinner wall to pass through (e.g. for finished-side preference), the default rule fights you. Set the priority explicitly in the inspector — do not rely on the default for design-critical joints.
- Gaps after edit: moving a single wall endpoint can break mitering on adjacent walls. After any major wall edit, run
Tools → Re-miter allto refresh corners across the project.
