Automation Parameters

[mmustaq]

Hello Everyone,

I have designed a fuel tank with some defined expressions.
Dimension Length=719mm, Width=334 and the Height= 560mm
The problem is if I increase the length to 50mm then the new length increased to 769mm. But the other parameters are not increased, especially blend edges are showing error. How to write the formula for blend edge so that if I increase some length the blend edges should also increase the same length automatically,

Note: The increased length '50mm' is undefined, its just an example. We dont know how much we increase. May be 10mm or 20mm or 50mm.

Thank you in advance,

Regards,

Without having the model, or at least seeing what features were used to create the model and what their relationships are to each other, it would difficult if not impossible to determine what might be causing this issue.

TO JohnRBaker,

Please find the attached file, a tank model in UG/NX 9.

OK, is this better (see attached model)?

Unfortunately, what I had to do to make this work if more complicated than what I could explain here in detail. What you need is some mentoring so as to developed better modeling practices. For example, it's often better, on something as complex as this, to not try and create all your blends with a single feature. It's better to create a series of simple blends then a few complex ones, particularly if this is going to be a model which parametric changes are going to be made to the overall size, as you're doing with this model. Also you should probably make your sketches fully constrained, or at least more constrained than what you've done so far, particularly any sketch which is going to moving as a result of the parametric edits of the overall size of the model.

Anyway, take a look at what I've done and perhaps you'll get some ideas on how to improve your techniques.
