if you never use pro|e, stop reading lest you get a serious case of CAD envy.
If you do use pro|e, yet of never heard of trajpar (short for “trajectory parameter”), it is a parameter that varies from 0 to 1 along the path of a sweep (0 at the start, 1 at the end). Combining this relations gives you an amazing level of control over your model.
For example, if you want a pure, trigonometrically pure transition from one value to another (comes in very handy when you get into high-end surfacing).
The reason I bring this up is that I’ve recently had occasion to some surfacing that need be both scalable and smooth. Under such circumstances, I have found the following to be immensely helpful. (pdf here)
If you have any questions about trajpar, or if you think you may be able to use this in a model but aren’t sure how, hit up the comments. I could talk about trajpar for hours.
