On-line training of freehand curve identifier FSCI in sketch-based CAD system

Abstract: As a freehand curve recognition method for sketch-based CAD systems, we previously proposed the Fuzzy Spline Curve Identifier (FSCI), which identifies a freehand curve as one of seven types ...

Discrimination between command and drawing strokes for sketch-based CAD interfaces based on fuzzy spline curve fragmentation

Abstract: In this paper, we propose a command stroke (CS)/ drawing stroke (DS) discriminator that distinguishes input penstrokes into CS for command input and DS for geometric-shape input, with the ...

Drawing the Hilbert Curve in OpenGl using Python

The order in which the sub-squares are visited determines the final shape of the Hilbert curve. **Step 1 ** The hilbert_curve function is the core of the Hilbert Curve generation. The initial call to ...

New CAD lowers the learning curve

The developer of AnvilCAD Lite says it is the first in a suite of new software packages that will change the way designers learn and use CAD. A closer look at the mechanical CAD application shows it ...
