Law Curves for a Toroidal Curve
Law Curves for a Toroidal Curve
(OP)
Hi,
Trying to create a toroidal curve in NX (7.5) basically that represents a transformer part. Have tried using various curve features to produce it with no success so far. Found law curves and think this is the way to go but have no idea how to use it, guides were less than useful but to be fair quite a complex topic so understandable.
Have attached a file showing what I am aiming to do but this was done in another package (sacrilege!).
Any advice or similarly produced parts would be great.
Thanks in advance,
Dan

RE: Law Curves for a Toroidal Curve
1. Create an arc with the same anlg eas you coil pitch
2. sweep a rectangular section along the arc creating a sheet body.
3. create a line at the end point of the arc (either in a sketch or just a line) with distance the same height as your retangular section
4. Use swept with orientation set to angular law, end value the same as your pitch to create a twisted helical type surface along the arc.
5. Intersect the swept helical feature and the retangular feature
6. Sweep a tube along the intersected curves
7. Use Pattern feature to create a circular pattern of the body

Huge thanks for the help. Running through your first post but keeps falling over at step 4. Any chance of a screenshot/further detail to see where I am going wrong?
Can't open the file as running 7.5 so keeps complaining it is a newer version but thanks for trying.

Massive thanks for the help. Parts are exactly what I wanted now I've just got the fun of putting them in a linked Part Families spreadsheet. The fun never stops.
Thanks again,
Dan
