Edit datum points with PRO Program

  • April 4, 2023

I want to create a curve from datum points. To do this, I have imported the datum points offset as a table and created the curve that way. Now I want to automate this process so that I can re-import the points every time I need them and update the curve automatically. Is it possible to import the points table using PRO/Program?

This looks similar to mapkeys. Unfortunately I am not really familiar with using trails.

Hi,

if you have "zero" experience with trail file then it would be better not use it. FYI ... when you start Creo session and do some work in it then almost every action is recorded into trail file. Its name is trail.txt.n by default. When you finish Creo session, you can rename the file and edit its contents. Later you can replay resulting file in next Creo session. This enables you repeat recorded actions.

I think if you search community web, you will find more information concerning trail files.

 

Maybe it will be enough if you write a procedure How to update the set of points into Word document and use this document, when you need it:

  1. open new datum point table in Notepad outside of Creo
  2. in Creo edit definition of point feature
  3. click Update button
  4. delete old point table
  5. copy new datum point table from Notepad
  6. save
  7. finish edit definition action
  8. regenerate model.

Q: Why you need to automate the process of editing datum point definition?

Pro/Program is not the best approach to automate the import of data. I am not sure if it is even possible with Pro/Program.

 

If you structure the design intent of your model in a way that regenerates when importing new point data then you could use one of the API (Toolkit, J-Link etc.) to read in data but unless that is a function call in the context of a larger program, I don't see how it saves you any time when modeling.

 

You could create a mapkey to read in the points file and regenerate the model. This would enable updating the points with a button push. A mapkey would be my suggestion to deal with this.

Thanks tbraxton for your reply.

I was thinking the same thing, but I was hoping it might work somehow with PRO/Program.

To be able to do this change, following trail file has to be generated and replayed.

Note: Below shown trail file works for my part, only.

Hello Martin,

thanks for your answer.

This looks similar to mapkeys. Unfortunately I am not really familiar with using trails.

How can I create one for my case?
