Dimensional Constraints

The DIMENSIONAL CONSTRAINT commands allow you to control objects through dimensions. A good way to look at it is, “Regular AutoCAD Dimensions” update when the object changes size and so on, but with “Dimensional Constraints”, it’s like the opposite, the object changes when the Dimension is changed. In the latest version of AutoCAD now includes a new Convert option to convert associative dimensions to dimensional constraints rather than it being the default behavior.

Creating a fillet automatically applies coincident and tangent constraints between the new fillet arc and the existing lines to help maintain the fillet if the arc or lines are modified. Likewise, creating a chamfer applies coincident constraints between the new chamfer line and the existing lines.
