NX9 - create point on curve in NX similar to CatiaÆs Euclidean distance option 1

[mathisudar2007]

Hello All,

How to create point on curve in NX similar to Catia’s Euclidean distance option?

If it is not there, kindly suggest me some work-around methods if available to achieve the same results?

I'm not sure you can position a point by "distance along curve" in NX.

But there are other features that you can position this way, such as datum planes and axes.

It depends what you're trying to model?

Although looking at the link you've given, Euclidean is the absolute distance along the curve?

In which case you could just to that in a sketch.

Hi,

I need to create a smart line between two points, one is on the 3d space(the point is fixed here) and another point(position variable) is on the existing curve.
The end use of this model is for doing kinematic motion.

Thanks,
Mathi K

From what I can see, from your document and what I found on my own, the 'Euclidean Distance' is the simple distance between two points, but I assume that this value would be imputed into a function which would then create a point on the curve where this 'distance' would intersect with the curve.

Now with respect to being able to create a point some distance along the curve, that's not a problem with NX as the normal Point on Curve using the 'Arc Length' Location method will do that for you. However, there is no function to directly create a point using the 'Euclidean Distance' however, it can be worked out using one of two schemes depending on whether the curve is 2D or 3D. If it's a 2D curve than all you have to do is create a circle whose center is located at the start of the curve and the radius is equal to the desired 'Euclidean Distance'. The point of interest would then be the intersection of the curve and the circle.

In the case of a 3D curve, you would use a Sphere instead of a Circle to define where the point is located. Now this could be put into a journal to automate the process keeping in mind that you could then hide the Circle/Sphere.
