Is it possible to draw 2D shape from location coordinates?

 

Thank you for stopping by this topic.

 

I would like to reduce time to draw complex shape models with Creo.

 

I have location coordinates data of the forms thus I selected each location to draw the shape.

If it's possible to draw the geometry directly from the location coordinates, it helps a lot.

Do you have any ideas to perform it?

 

Thanks!

Sorry I do not understand your question, but I think I am doing something similar.

I design cam using Matlab (anyone can use Matlab basic online for free) and create 3D shape of the cam in Creo, following the steps below:

 

Calculate in Matlab -> export cam profile coordinates as txt/xlsx -> save exported data as .pts -> create points in Creo by importing the .pts file -> create curve from points -> extrude (in the sketch, offset 0 from the curve) -> done.

The process can be automated with mapkey and automation script.

Thank you for your comment.

It is possible for Matlad to create cam profile from location coordinates (each location coincides with the apex of the shape profile)?
If so, the 3D shape can be created with the following procedures you mentioned.

Sorry I am not sure I understand your question.

If you have all coordinates, of course you can generate the cam profile.

In my case, I use the timing diagram to calculate all the coordinates necessary to generate cam profile.

Note that the cam profile is different from the pitch curve. In a Youtube video, the poster generate the pitch curve and use that curve as if it is cam profile. 

I am also having a same type of question . Mynordstrom Login

I have a home-project to develop linear cam profile with roller follower In the way that appear in the picture. I found it only on a video on youtube after hours of searching but without any code or even a description if it can be done on or not. my deadline is approaching so please help me to get this done. thank you

Yes, it is possible. See my answer to this previous post.
