Export coordinates of multiple coordinate systems

Hello,

I am trying to get a list with the X,Y,Z, and yaw, pitch, roll for coordinate systems that I have patterened across a curved surface. I have not even been able to figure out how to pull the location data for just 1 coordinate system. Can anyone help me on this?

Solved! Go to Solution.

I think, my advice about Excel is not useful in your case.

Export to text-based file it is more interesting solution. Thanks to Antonius.

Take a look at Neutral (.neu) file.

3 id 57613

3 name CS2

3 e1 [3]

4 e1 2*0.,1.

3 e2 [3]

4 e2 0.,1.,0.

3 e3 [3]

4 e3 -1.,2*0.

3 origin [3]

4 origin 0.,1.75,0.707106781186547

2 coord_systems ->

e1, e2, e3 - coordinates of the axes (a vectors from the origin).

You can check this by placing Point - Offset Coordinate System and make the Analysis (Geometry Report - Point)

I think, *"e1 2*0., 1."* this is *"e1 0., 0., 1."*

Have you tried exporting to various ascii-based formats to see what the data looks like?

If you wanted to share the file, we could look at it.

If you can get the data, or at least a subset of it, what did you want to do with it?

Here is the part file. I have started with a super simple shape, and I know once I have the location of the first 2 rows, the rest are easy. But eventualy this would be a more complex curve.

I have tried exporting to a couple of formats, but so far none export any but the default coordinate system.

Once I have the points, they will be fed to a robot.

I exported a similar file to STEP. it returned good data but it returns in Cartesian coordinates with coordinates and vectors. You will need to convert this data to the desired format.

Have you talked to some of the CAM people to see if they know a simple method? A 5-axes milling machine crunches numbers like this for breakfast.

The STEP file has some good information. I was able to pattern lines going out normal to the surface and get the starting point with a direction. I am not sure how to interpert the direction vector though. What shoudl be straight up has a direction of .4956, .8686, 0.000.

I'm going to guess here... probably a location from the "master" 0,0,0 origin... with a vector back to the position of the feature.

I have not used an Excel Analysis before, but I will look into some examples.
