Importing coordinate points in Design Modeler

      Hi everyone,


      I am trying to import coordinate points to Design Modeler to get a curve. I have  created a text file which contains 5 columns: Group ID, point number, X, Y, Z coordinates. The geometry is 2-D (all Z-coordinate points are 0). I have a simple curve which is not closed. As of now, I am able to import the text file successfully, but when I try to connect the coordinate points using 3D curve option, I get an error while choosing the last few points. This is the error:


      "invalid point selection. The curve would become self intersecting"


      What could be the reason? Any thoughts?

      first import points. 


      then try to create curve manually in DM. please see if you can create this curve and it is not self intersecting.

      Dear kkaade,


      This is exactly what I did!!! I cannot simply select few points because of this error. Any other suggestions?

      Can you attach your text file so we could take a look at it?

      I changed the units from the default meter to millimeter when I imported the points and it worked fine for me. Additionally, if you add the line 1 0 at the end of the coordinates file, you will get a closed loop. See attached screenshot:

      Hi Adarsh,


      I had a similar error. The fix was to use same format of numbers as used in your ansys; that is if a comma or dot is the correct input for decimal place.

      Hi


      when I import points, i got an error "no of points generated 0". I followed the same steps of importing the .txt file but unfortunately I didn't get points in Design modeler.


      Waiting for any kind answer.

      Hello 


      Check the ordering of the points, as like to be from the leading edge through the upper surface then from trailing edge through the lower surface, the idea is not to make the curve self intersected.


      you can reorder the points with excel.
