Hi 

I want to import polar coordinates from Excel and draw a spline through them.

In autocad mechanical its easy.

i chose spline and then copy paste all the coordinates from an excelsheet  

eksample of the coordinates

R coordinate and angle starting from zero ending in 360 

330.24185<0
330.24306<1
330.24672<2
330.25282<3

Is it possible to do this in creo parametric ?

Hi,

 

in curve4.zip file you can find two example models. In both cases I used curve4a.pts file.

I found out how to import .pst file 

Sketch

Place a coordinatesystem in 0.0.0 in the drawing

and then draw a spline then rightclick the spline and modify.

under the tab file 

choose the coordinatsystem that you sketched and then import.

The problem is that i get is that the format of my coordinates probably doesnt match what creo wants so the Points in the spline doesnt get updated.

So my new question is how should the input file look like describing the coordinates?

This is what i have but its easy to modify 🙂

Radius value and degree value from 0 degrees to 360 and last 0 again to cloose the loop

330.24185<0
330.24306<1
330.24672<2
330.25282<3
330.26134<4
330.27230<5
330.28567<6

i looked at your file and it looks ok 

and if i put in cartesian coordinates it would probably work to import them

Was it cartesian coordinates that you used ?

But i only have radius coordinates and the angle.

could you include the excelfile you used?
