MSection

The MSection program creates and manipulates Cross-Sections using a cutting line on meshes, polylines and 3Dfaces. It acts as a floating toolbar in AutoCAD R14 or AutoCAD 2000 and includes the following tools:

Cross Section

Produces the cross-section points or dots created by cutting lines intersecting with meshes and polylines.

Join the Dots

Converts the dots produced by the cross section tool into a sensible cross-section line.

Smooth Polyline

Takes a polyline, and applies a smoothing algorithm to it, to remove some of the errors on difficult cross-sections.

Join Polyline

Joins together several polylines that nearly touch, typically created as partial cross-sections into one polyline.

Convert to Mesh

Converts a series of polylines, typically created as cross-sections, into a mesh.

PDesign

The PDesign program assists a paraglider designer in creating a production ready drawing from an initial design specification. It acts as a suite of tools in DesignCAD 3D and includes the following tools:

Outline

Assists in drawing a basic outline of the paraglider, with rib centerlines drawn in over the span shape.

Insert Ribs

Replaces the rib center lines on the outline drawing with pre-drawn ribs, scaled and rotated to fit.

Produce Panels

 Creates the top panels, bottom panels, ribs and optional diagonal ribs as defined by the previous drawing.

Add Seams

Add seam allowance and stamp a panel number on each selected rib.

Generate Lines

Create the line divisions and junctions required to define the rigging system

Relax Lines

Allows the lines to relax into their natural positions, and prints out the required line lengths.

MSmooth

The MSmooth program creates smooth AutoCAD polylines, including embedded arcs, from a rough polyline. The rough polyline could come in from a traced bitmap, or from a mechanical tracing sensor, and can include loops, kinks and reversals. It can apply several techniques, including regression smoothing and least path distance to reduce the data into a form smooth enough to be sent to a laser cutter, without loosing definition.
