Hey Guys, am in Customization of AutoCAD and the problem am facing is with dimensions.

Am able to get normal dimensions but problem lies in Parametric Dimensions. Any Ideas on how to perform this Linear Constraint Dimension

Hi amitk_189,

Sorry, what is it that you want to do exactly? Do you want to create a dimensional constraint from API? Retrieve information about an existing one? or...?

Creating constraints through the parametric API is a relatively involved task. We created a higher level API in order to help programmers who intent to work with it:

In Parameter Tab we have Linear Dimensions, Aligned Dimensions.

Lets draw a Line and the dimension of this line is 15. Now if i change dimension to 25, the length of line should change to 25. Did you get it now?

And i found this solution you provided in link long time ago but did not succeed in it. I did lot of coding on it but was not able to get things in right order. If atleast one example would have been there it would be helpful.

Philippe & Gopinath,

Just wanted to say thanks for the API in link above and is very useful.

amtik_189,

If I understand you correctly I accomplished what you described using the test commands in MgdConstraintAPITest

MGHLDIMALIGN - to add dimension

MGHLPARAM - to change the "expression" or length of line.
