Recommended test
Classify one current project output as geometry, quantity, visual or experimental and verify it with the matching check.
- Pick one feature you intend to deliver and find its status in this Knowledge Base.
- If it is geometry, measure it; if it is quantity, trace it to the model; if visual, compare it with the source.
- Repeat the feature's recommended test in a disposable project.
- Record any project-specific assumption or unresolved limit before continuing.
Geometry is not engineering
Build Generator, Truss Builder, Opening Framer and Custom Solid create useful geometry. They do not calculate structural capacity, regulatory compliance, fire performance, drainage design or fabrication tolerances. Use qualified project checks for those decisions.
Visual detail is not quantity
Textures, contrast lines, AI renders, detailed roof coverings and scale people improve communication. Their appearance does not necessarily create a billable product or exact construction detail. Trace quantities through cutlist/BOM metadata and verify products separately.
Experimental tools
The general toolbar Plane Tool and Solar Shade are experimental features. Custom Solid’s saved sketch-plane controls are a separate workflow. Pattern > Fill pattern creates Isogrid sketch lines and estimates; Apply does not cut pockets into a body. Along path repeats selected sketch shapes and has its own editing and trimming behavior.
Dormers support compatible gable hosts, including conventional rafters and supported A-frame truss openings. Build > Dormers also supports Hip sides A and B, with clearance from the diagonal hips and ridge; Hip end slopes and skillion hosts remain unsupported. The assembly-guide preview has narrower coverage than the building generator, including limits on dormers and roof families. The new rafter Sauna is outside the older chord-and-post guide adapter.
Current Custom Solid scope
The OCCT workspace is available from the ordinary app address. It supports primitives, planar face sketching, sketch and whole-face Push/Pull, Fillet/Chamfer, Revolve, Sweep and Loft with optional rails. Sketch regions also support Tilt and Wedge about eligible straight boundary edges. Whole-face Push/Pull offers Move face and the four extrusion operations. These tools work on current Custom Solid bodies, not arbitrary generated framing or imported display meshes.
Sketches, planes and exact bodies save together. Source edits do not replay a parametric feature tree. Curved-face Push/Pull is not available. Loft currently requires profiles without holes, with 2–16 profiles and either no rails or 2–8 suitable rails.
Plane > At angle creates a sketch plane around a straight solid edge or sketch line, including construction lines. It supports signed angles and compatible reference planes. Curved hinges are outside this tool’s scope, and created planes stay fixed when their source changes.
3MF export exports selected supported bodies as checked print meshes. It does not include sketches or building framing, set slicer options or establish printability for a particular printer. Keep .strek as the editable source.
Floor planner scope
Build > Floor planner shares the building dimensions and exterior openings with the other designer modes. It supports connected orthogonal partitions, internal doors, room labels, dimensions and 2D furniture on available floors and compatible attic-truss lofts. The main footprint remains rectangular; extension settings remain in Dormers.
Generation creates non-load-bearing partition framing, finishes and internal doors. Furniture stays in the plan, with 3D support in development. Stairs, angled partition framing, arbitrary exterior footprints, automatic structural sizing and a dedicated floor-plan PDF exporter are outside this release. Loft headroom and roof/dormer graphics are planning aids, not complete construction sections. Use Project Planner for sheets from the generated model.
Hip roof V1 scope
The Hip roof generator supports rectangular and square footprints within the existing building limits, with one shared pitch, a uniform overhang and level eaves. Framing, optional roof layers, fascia, flashing, gutters, downpipes, four-wall siding and eight equal-length corner boards are included. Roof appearance, thickness, vertical offset, downpipe adjustments and Simple Panel wall controls work live after generation.
Compound footprints, different pitches on individual faces and Hip-specific Create assembly guide instructions are outside V1. Detailed Hip covering models flat-tile courses; Wave and Standing seam live styles change their surface pattern, not the physical tile profile. Normal selection, groups, timeline, cutlist and project saving remain available.
Hip roof V1 was released on 13 September 2026. Existing Hip geometry predating live controls requires regeneration in the updated build. Save a project copy before replacing a manually edited building.
Plan-dependent outputs
GLB export, PDF limits, premium branding, suppliers and AI credits can depend on the active plan. The live account and tool dialogs are authoritative. Save a project checkpoint, run the article’s green test and inspect the actual output before making it part of a customer commitment.
