Seam Allowances
|
MPanel allows different types of seam allowances, depending on
your assembly method. This tutorial describes how to apply those
seam allowances.

|
Geodesic Seams
|
Creating geodesic seams on a saddle tent. Geodesic seams are
often used to minimize seam lengths and create substantially
rectangular panels. MPanel can create geodesic seams from any
boundary points over any number of meshes, and can then turn the
seam lines into a new mesh, to ease paneling.

Specified Width Panels
|
How to make panels of a specified width. Illustrates working from a
geometrically fixed seam to produce a series of specified width
panels.

Merging Panels
|
Looks at the issues involved in merging panels, and shows how the
shearing error occurs. Merging is a powerful technique for joining
panels together and achieving panel end curvature, but it has
implications in the way the fabric stress relaxes that need to be
understood. This drawing illustrates those issues for a simple hoop
structure.

|
Diagonal Seams
|
Creates a set of panels running diagonally on a square sail. Diagonal
seams are required for aesthetic or structural reasons, and MPanel
can create them nicely, although there are difficulties with the corner
triangular panels. This drawing illustrates the process.

This pdf explains the procedure for calculating the compensation on
panels.
