Sketch in multiple location

Sketch in multiple location

Sketch in multiple location

(OP)
Hello,

I have a 3d spline and I when I sweep a sketch I made using the 3d spline as a guide, the result kinda twist a little bit.

I create a datum on intervals and copied the curves of the sketch over.  I have 6 sketches in all.

Is there a way to control all the sketches using just the dimension on the 1st sketch?

What I did is make the dimension of the other sketch equal the 1st but with a lot of dimensions, it tends to be tedious.

I still have 5 other parts to do and all of them would have the same situation

Is there a faster way of doing this?

TIA!

RE: Sketch in multiple location

It might have been easier to provide a second curve which would act as a 'guide' to control the alignment of the profile as it was swept along your 3D spline.

Perhaps if you could upload your example someone might be able to provide you with a solution which would be MUCH more elegant than creating multiple associative instances of a sketch.

RE: Sketch in multiple location

I have a suggestion that may not be any help for this instance but is very helpful in other situations where one initially creates a bunch of indentical things and then wants to change just one. I create an expression (with a descriptive name) for each dimension, and then reference the dimensions in each sketch. From there if one needs to change a dimension in all of the sections you can sort for the expression name and change it, if you need to change a dimension in a single section you can either go to the sketch and change the instance of the dimension or if you have also named the sketch dimensions descriptively you can sort and change the value or add a delta to the expression. it might be possible to copy and paste the sketch if you have created the sketch on defined datums and created the dimensions in away that you can re-associate the references. I also use import part a lot which automatically adds numeric postfix identifiers to the expression names that make it easy to determine which sketch is using the expression.

It is important to think out your expression scheme as much as possible. I must add that the expression too in UG is really fabulous. The ONLY thing I miss is a search and replace function (as of NX5).

Good luck working with expressions is complcated but hugely rewarding!

RE: Sketch in multiple location

Just want to add praise for the UG expression system : )  If you've had experience with, say, Solidworks' expression system as well, you know how much more powerful and user-friendly the NX expression system is.
