CAD Tools

Geometry for CAD and drawing standards — what you need between the idea and the drawing.

Geometry & DXF

Ready geometry for SolidWorks, laser and CNC.

NEW

Spline DXF converter

Instead of hundreds of tiny line segments you get a few smooth splines you can edit, offset and extrude in SolidWorks.

Example: The example part (a circle made of 144 segments, a cam of 220 points) → a few splines and circles, scaled to 100 mm wide with a frame. Open the tool →

Drawing standards

Tolerances, fits and roughness — what to write on the drawing and in the title block.

NEW

Tolerances & roughness

ISO 286 fits, ISO 2768 general tolerances and Ra roughness in one tool — limit sizes and how to write them on the drawing.

Example: Ø 25 H7/g6 (sliding fit) → hole 25.000–25.021, shaft 24.980–24.993, clearance 0.007–0.041 mm. Open the tool →
