Used to convert a dimension into a dimensional constraint. This tool works only on dimensions that have not been previously constrained with the Dimension Element tool.

When MicroStation is running, it is possible to convert dimensions that are not associative. Since a non-associative dimension is not associated to any element, an attempt is made to link the dimension to an element based on the possible type of dimensional constraint the dimension could become, the element type(s) it could apply to, and the element the dimension touches or is aligned with.

Possible problems when converting a non-associative dimension are as follows:

• If no suitable element can be found, the message “Targets not found” displays in the status bar.
• A constraint is created, but it is incorrect or unsatisfactory.

If you cannot satisfactorily convert a non-associative dimension, delete it and replace it with an associative dimension to specify exactly the desired constraint.
