I am new to NX. I have been using CREO/Pro-E for years and recently just got NX 10. I have attached a word.doc that illustrates my qustion. In Creo in the variable section sweep tool you can modify the individual dimensions of a section with a formula or something like a law curve. I always found this to be very powerful and wondered if there was something similar in NX. I understand that the area or the perimeter of a section can be controlled by a law curve but what about just one dimension in that section? For example, in the attached picture you could control the .5 dimension with a law curve as it sweeps around the path(circle). This is how you could make a cam for example. Can you control one dimension like that and if not is there another way?
Solved! Go to Solution.
Thank you for responding to my question. I read that discussion and opened up your part. I like how you were able to offset that curver based on the other law curver. I guess my question is can you modify individual dimensions in a section with a law curver or formula. For example, the feature that you created with the swept had its sectrio controlled with a law curver that affected the perimeter. Therefore the whole feature was symetric about the x-y plane. But what if you wanted to have one side of the rectangluar cross section be controlled by a law cure or formula and have another side of the rectangle controlled by a different law curve or function. Also, maybe I need the variational sweep which I am okay with.
Could this also be done in a variational sweep. I know you can keep adding sections to a variational sweep and change the dimensions in each seciton. Could you vary one of those dimensions with a formula that acts on that dimension over the whole guide curve?
attached there is a variational sweep in which the dimension of the section is determined
by a formula that acts over the guide curve.
I hope this answers your question as I understand it, please post a part example if this is not
This is pretty much what I was trying to do. Thank you for taking the time to answer. I am guessing that if you had a rectangle you could vary each side of the rectangle with an expression as it varies over the guide. My last question would be if you can vary a dimension with a curve. Similiar to the cam in the word document that I attached. If not then I guess you could just vary the cross section with the guide curve. Thanks again.
yes, you can change each side of a rectangle (see attachment).
As far as I know, there seems to be no easy way to get a parameter (i.e. a dimension) out of a curve (unless concocting some complicated sketch with measurement, which is not worth).
So, I think you have to resort to some sort of curve (a couple examples in attachment).
