cables

[tadej001]

Hello again,

My intention is to make a cable in NX 5 as deformable part.
I would like, that when this cable is inserted into an assembly it changes its shape. But also that the lenght of athe cable is the same as it is in the not deformable part.

Any suggestions?

Thanks, Tadej

In theory, you can do this with the Electrical Routing application if you have a license for it. That application is not straight forward to figure out. Otherwise your deformable part idea is the next best thing. Can you constrain a spline by locking its length?

I know there is route mechanical...but don't have the license.

I can't lock the lenght of the spline. The derfomable part thing is also complicated becouse I can't insert the spline as reference object into deformable feature. I'm trying to make a deformable part...so that once inserted into an assembly it could change its shape but the lenght remain the same.

I can't figure out how to do that.

Maybe the best thing is to by the license

thanks, tadej

Experiment some! Can you make a deformable component? If so, then the wire is made the same way. Don't worry about the length, the deformable string that you map the straighht component to can be any length. Yes, I understand your need for the deformed shape to be the same length as the straight piece. You will have to adjust the spline that drives the deformable condition so it is the same length as the straight piece centerline.

If the thing is a regular shape composed of lines and arcs and nothing more you may be able to do this using sketches and parameters, but if you intend to use a spline then you're probably better to treat it as an approximate science.

The question is reasonably frequently asked but what most people don't supply is what their expectation might be if the curve is either too short, too long or in some cases contorted to bend radii that would be considered too tight. The cable routing package seems to be able to do this and more in cases where I've seen it used by others, but of course it comes at the cost of the extra license.

If you can work to a general rule of thumb that says the distance between the two ends of the curve ought to lie between say 1/2 and 3/4 of the cable's actual length then you could successfully approximate without being too precious about exactitude. Putting that kind of logic into a deformable part may be something you could do with some effort but whether you'd bother is doubtful since you could just as easily do it in a layout and set the cable in place later on. At least that's what most people would usually do.

Most designers using NX are only regularly concerned about the installed condition of cables in a static location for most of their work. Examples of other possibilities using deformable parts may be possible but you'd need to be a lot more specific in order to be able to set up something like that. Certainly with infinite variance you'd have no finite control over the length of cable required. So at some point you always have to conspire to keep the end points within an achievable range.

Thank u Ben Loosli and Hudson,

I made some sort of cable n using spline and put a measure on it. Then I used the edit->curve-> lenght to set the lenght parameter to the spline. I don't like that when I change the lenght with edit...crve.. function a new curve is made. Bu tok...it is acceptable.

I can't make this cable only in layout becouse I have the part number for it and its lenght is specified on the drawing.
Also heve an assembly behind.

I'm considering to buy a license for route mechanic.

One onother question regarding UGS support. In our county we have one reseller for UGS. But they are only in 5. One is for TC and one for NX. They implementing TC and NX in our company. But they....how to say...aren't the best support team. How are they arounf the worl. Any experience with them?
