CREO PRO PROGRAM

[SS4598]

I want to use negative integers in input as my coordinates of datum points are negative as well as positive. Is it possible to enter negative integer using Pro/Program.

Yes, you can enter a negative integer value in a Pro/Program input.

Can you please suggest me how to do so as I tries entering $ sign in relation part of Pro program but it did not work as when I enter negative integers geometry is not updated.

[tbraxton]

Do you have a test case that you can post here? It must be in Creo 7 or earlier for me to open it. Educational license models I will not be able to open either.

INPUT 

H  Number

"Enter the horizontal distance of datum point"

END INPUT

RELATIONS

D26 = $H

END RELATIONS

This is the general syntax I am trying to implement to check if on entering negative number in H to change x coordinate of datum point with dimension notation of d26.  This does not change the coordinate value. What is mistake in this?

Thanks in Advance.

Hi,

try this

$D26 = H

The values are getting updated when I check the displayed values remain positive and stored value changes to negative, which is my input.

Hi,

did you set show_dim_sign yes  in your config.pro ?

Please attach pictures describing your situation.

Hi,

I attached part created in Creo 7.0.5.0.

show_dim_sign yes is not necessary setting in case of point offset from coordinate system.

Also replay ProProgram.mp4.

Hi,

please read https://support.ptc.com/help/creo/creo_pma/r10.0/usascii/index.html#page/part_modeling/part_modeling/About_Editing_Dimensions.html help page. Maybe show_dim_sign yes  config.pro option will resolve your problem.

Hi,

what Creo version do you use?
