Hakan Seven 49fddea1ef fix(scene): include camera_generation in hatch/wipeout cache keys
The Phase 2.1 step-4 change made `synced_hatch_models` and
`wipeout_models` view-cull through `entity_index().query_rect`, but
left both caches keyed on `geometry_epoch` alone. Cache hit would
return a list culled to a previous camera's view, dropping hatches as
the user panned. Now keyed by `(geometry_epoch, camera_generation)`
— same pattern as `wire_cache`.

`image_cache` stays geometry-only: images self-cull per frame via
`vp_scissor` in the GPU pipeline; the cached list is camera-agnostic.

H7CAD

resim

A CAD application for 2D drafting and 3D modeling, built with Rust. Reads and writes DWG and DXF files natively.

Features

File Formats

  • DWG read/write (R13 through R2018)
  • DXF read/write (R13 through R2018)
  • STL export (STLOUT / EXPORTSTL)
  • STEP AP203 export (STEPOUT)
  • OBJ import (IMPORTOBJ)
  • PDF export (plot layouts to PDF)
  • WBLOCK — write selected entities or a block to an external file
  • XREF — attach, reload, and auto-resolve external references

2D Drafting

Command Description
LINE, PLINE, RECTANG, POLYGON Basic geometry
CIRCLE, ARC, ELLIPSE, SPLINE Curves
HATCH, HATCHEDIT Hatch fills with pattern, scale, angle editing
OFFSET, TRIM, EXTEND, FILLET Modify geometry (supports lines, arcs, ellipses, polylines, splines)
BREAK, STRETCH, LENGTHEN Shape editing
ARRAY, MIRROR, MOVE, COPY, ROTATE, SCALE Transformations
EXPLODE Explode blocks, dimensions, polylines, mlines
DDEDIT Double-click text editing
MASSPROP Area, perimeter, centroid of selected entities

3D Modeling

Command Description
BOX, SPHERE, CYLINDER Solid primitives
EXTRUDE, REVOLVE Profile-based solids
LOFT Ruled-surface loft through cross-sections
SWEEP Sweep a profile along a path
ARRAY3D 3D array
ACIS tessellation Renders 3DSOLID, REGION, and BODY entities

Annotations & Dimensions

  • Dimensions: Linear, Aligned, Angular, Radial, Diameter, Ordinate — with full DIMSTYLE support (DIMASZ, DIMSCALE, DIMEXO, DIMEXE, and more)
  • Text: MTEXT, TEXT, DTEXT with font browser (STYLE DIALOG)
  • Leaders: MLEADER with straight and spline path types; MLEADERSTYLE manager
  • Tolerances: GD&T feature control frames
  • Tables: TABLE entity render; TABLESTYLE manager
  • MLine: MLINE entity with MLSTYLE manager and EXPLODE support

Paper Space & Layouts

  • Multi-tab layout system with model space and unlimited paper space tabs
  • Viewport projection: Model content correctly projected into paper-space viewport rectangles
  • Camera persistence: View position and zoom saved per layout; restored on file open and tab switch
  • Correct paper size: Physical paper dimensions read from embedded PlotSettings (not drawing limits)
  • Inline MSPACE overlay — enter a viewport with double-click; edit model entities in place
  • VPORTS — preset viewport configurations (single, 2H, 2V, 4-way)
  • LAYOUTMANAGER / LAYOUTPANEL — GUI layout manager
  • PLOTSTYLEPANEL / STYLESMANAGER — plot style table editor (CTB/STB)
  • PRINT — send layout to system printer

Blocks & References

  • INSERT with attribute prompting (ATTREQ)
  • ATTEDIT — edit block attribute values interactively
  • REFEDIT / REFCLOSE — in-place block reference editing
  • XREF — attach, reload, and resolve external DWG/DXF references
  • DATAEXTRACTION — export entity property data to CSV

Snapping & Precision

  • Object snaps: Endpoint, Midpoint, Center, Node, Quadrant, Intersection, Perpendicular, Tangent, Nearest, Insertion, and more
  • Ellipse arc endpoints, LWPolyline arc midpoints, Hatch boundary points
  • Object Snap Tracking (OTRACK / F11)
  • Polar Tracking with configurable angle increment

  • Grid snap with adaptive spacing
  • Command history navigation (↑ / ↓)

Rendering
