1: CREATING THE SPLINE CURVE
began this part using Adobe Illustrator, but it could easily have been
accomplished completely in Modeler.
Like to start most of my models by drawing the basic shapes in Adobe Illustrator.
I am very familiar with this program and find it very easy to work with.
I decided to create a square knot for this tutorial because it is easy
to model. Using a knotted computer power cord as a guide I drew the shape
below and saved an Illustrator 8 file. (Modeler can not load Illustrator
files saved in version 9 format).
imported the Illustrator file with Modeler's EPSF Loader which is located
under the File: Import: popup menu button. I set the loader to create
a Spline curve with a fine resolution.
used the bend tool to bend the front of the knot loop up. I only have
to make one loop as the second loop is the same shape as the first, just
used the bend tool again, this time with a manual falloff, to make a bend
in the opposite
second bend done:
spline curve might be done, but to check it I rail extruded a disk along
made two copies of the rail extruded shape on different layers. Using
these I was able to see that the two ropes intersected each other too
adjusted the spline curve and tried again, this time with more acceptable
results. If you wanted a simple knot you could stop here. But the more
complicated shape of the twisted rope can not be created by rail extrusion.
I deleted the two rope shapes as they were just to check the fit of the
spline curve shape.
selected the spline curve and chose the Make Skeligons command from the
