Hakan SevenandClaude Opus 4.7 7d9ac435cb feat(qselect): per-property filter with operator + value (#28) 
Quick Select used to filter only on Object Type and Layer. The classic
QSELECT model — pick a type, pick one of its properties, compare with a
typed value via a logical operator — is much more general: a Line entity
can now be filtered on Start X, Length, Angle, Delta Y, …, and any
entity on the common Layer / Color / Linetype / Lineweight.

Panel layout: Object type → Property → Operator → Value → Append. The
Property dropdown is type-aware: it always lists the four common
properties; picking a specific Object type appends that type's
`geometry_properties` rows, sampled from the first entity of that type
in the active layout (so `Start X`, `Radius`, `Pattern Angle`, … only
appear when their entity type is selected). Changing the Object type
drops the Property when the new type no longer offers it.

Operators: `= Equals`, `!= Not equal`, `> Greater than`, `< Less than`,
`* Any value`. Eq/Neq do case-insensitive string compare against the
canonical property string (so "ByLayer" matches "bylayer"); Gt/Lt parse
both sides as `f64` and reject anything non-numeric; Any skips the
value test entirely. The Value text field is disabled when no Property
is picked or the operator is Any. Append behaves the same as before.

The new value reader is hand-rolled for the four common properties
(layer name, color formatted as `ByLayer`/`ByBlock`/`<aci>`/`r,g,b`,
linetype name, lineweight formatted as `0.30mm`) and falls back through
`geometry_properties()` for type-specific fields — extracting the
property's value out of the `PropValue` variant so EditText / Choice /
ColorChoice all canonicalise the same way the panel will display them.

Open CAD Studio

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

Installation

Linux (AppImage)

Download OpenCADStudio-*-linux-x86_64.AppImage from the latest release, then:

chmod +x OpenCADStudio-*-linux-x86_64.AppImage
./OpenCADStudio-*-linux-x86_64.AppImage

No installation required — runs directly on any modern Linux distribution.

Windows

Download OpenCADStudio-*-windows-x86_64.exe from the latest release and run it directly. Windows SmartScreen may show "Windows protected your PC" because the binary is not yet code-signed — click More info → Run anyway.

macOS (Apple Silicon)

Download OpenCADStudio-*-macos-arm64.dmg from the latest release — Apple Silicon (M-series) only; Intel macOS isn't built.

Open the .dmg and drag OpenCADStudio.app to /Applications. The first launch may be blocked by Gatekeeper because the app is not notarised — right-click OpenCADStudio.app → Open and confirm, or run once via xattr -dr com.apple.quarantine /Applications/OpenCADStudio.app.

Build from Source

Requirements: Rust 1.75+

git clone https://github.com/HakanSeven12/OpenCADStudio.git
cd OpenCADStudio
cargo build --release --bin OpenCADStudio
