CAD requirements
NOTE: this is a collector page showing specific features which is required some basic CAD capabilities.
CAD
CAD is an acronym of Computer-aided design, which means basically some tech drawing abilities.
Some plans already exists at 0.52 milestone of the Roadmap.
This page is basically an effort to expand what is in the roadmap and provide some background of this planned features and add some more needed capabilities.
Implementation
Maximilian Albert are working many of these features, in GSOC 2008! Please see the detailed BlueprintGeometricAndTechDrawing blueprint for more info.
Needed capabilities
- Numerical input
- Measure tool
- Units should be consistent all over the codebase
- Transpose of the object center
- Geometrical constraints
- "Perpendicular-to", "Parallel-to", etc.
- More circle creating options
- Path trimming/extending/offset
- Filleting tool
- Dia-like smart shapes support
Numerical input
Ability to input the coordinates, distances, angles via keyboard. The include:
- Angle
- X-coordinate
- Y-coordinate
- Distance
Measure tool
Simple tool to measure the distance between two points. Could be extended into a poly-line measure tool.
Inkscape units
Architecture and engineering require different units, and different countries have different standards.
Most of the world: Metric
- Meters (architecture)
- Centimeters (architecture - europe)
- Millimeters (architecture and engineering)
- Nanometers?
US, some others: Imperial
- Inches
- Feet
- Yards
Please view BlueprintRealUnit for more details.
Transpose of the object center
TODO
Geometrical constraints
- Vertical
- Horizontal
- 15 degree increments
- Arbitrary increments
More circle creating options
Allow user to create circles
- Specifying 3 points
- Specifying the center and the radius (currently possible)
For more information please see the section "Typical workflow" of Albert's GSoC proposal.
Trim/Extend tool
- Trim cuts one path, or object at a point where it crosses another line. This could perhaps be an extension of the "path>cut" tool.
Fillet/Chamfer tool
Cuts the corner off two intersecting paths, and replaces it with another line
- Chamfer cuts a straight line
- Fillet replaces the corner with a curve (this is similar to the rounded corners on a rectangle, already implemented, perhaps some code could be reused)
Dia-like smart shapes support
applications:
