Extra bonus in true position between points and lines

[Carlos Gonzalez]

Hello everyone, I am new to this and I am having trouble measuring a true position which uses elements with points and lines, the difficulty is when adding the change or extra bonus to the position tolerance since it does not allow me to add them anymore that in this type of elements pcdmis does not give the option to choose, is there any way for pcdmis to do this automatically? The program already has calculations of the distances between points and lines, that is, I already know the size of the property but I need this to be considered in the bonus, please if anyone knows I appreciate it. I have PCdmis 2017 R1

You can't assign material conditions to non features of size such as points and lines. You can do the math for MMC manually and add them into the dimension as a variable, but if you want to do MMB, you can try using the Construct Width feature introduced since 2014. I've had both success and failures trying to use it.

You'll need to do line to line, or plane to plane for more consistency. Don't think you can use points.

Post a print and some code....

I understand that it is not convenient to use points for the true position, the difficult thing for me is precisely the development of these variables to add the extra bonus

Do you mean an example of what I am asking?

You could..pull the TP from a generic circle that is constructed from your points.

If need be, maybe you could use the below methodology to re-define your features.

Thanks, I think your option is a good idea, I will try to do it.
