FUN WITH BENDS

There are all kinds of fun and useful things that can be created with BENDS.

What is a BEND?

It's a method of "bending" or "wrapping" geometry.  This tip shows a couple of fun examples using TOROIDAL and SPINAL bends.  In both cases, they provide a way of changing geometry that was created in a "straight" state, to something quite different in a "bent" state.

Here is some simple 3-dimensional text in Figure 1.  This was done as a
SOLID / EXTRUDE, then SKETCH / ADV GEOMETRY / TEXT.

In figure 2 the text protrusion is "BENT" using a TOROIDAL BEND.
(For more information see the Pro/E documentation on TOROIDAL BENDS.)

For reference, figure 3 shows the sketch and dimensions used in the bend above.  The key to success with a TOROIDAL BEND is the position of the sketched coordinate system.  The X-Axis defines the neutral plane of the pre-bent geometry, so be careful in setting up your sketching plane.

Figure 4 shows a SPINAL BEND.  The SPINAL BEND also has its idiosyncrasies, but is a little more straight forward to apply.  This bend also has some neat functionality for graph driven geometry.

Look these up, they can be a really good thing to know!

Good Luck, and HAPPY NEW YEAR!
