When you look at using Dimensions as Constraints, i.e., Dimensional Constraints, you have to make sure that the dimensions are not annotative. You cannot use annotative dimensions as dimensional constraints. If I hover over this dimension, you'll see there's no annotative symbol appearing but a good way to check is just to click on the dimension itself, right click and Properties on the Shortcut Menu and you can see there that it is an associative dimension, which is what we need, associative. But annotative is not; an annotative dimension. So I can close that. It's always a good habit to get into if you're going to use dimensions as constraints to make sure as well in your Annotate Tab that you've got a standard dimension style. If I go into my Dimension Style Manager, you can see that I've got a Dims Standard Dimension Style. It's not annotative. It doesn't have the blue annotative symbol. So make sure that Dims Standard, Set Current is the current dimension style and close and basically that there is using my Standard Dimension Style. Now, if I want to convert that dimension to a constraint, I go to the Parametric Tab and in the Dimensional Panel here I click this icon here, Convert. Now, if I click on this dimension, it automatically puts the constraint in there. If I press Enter now, it makes it into a dimensional horizontal constraint. Now, watch. If I go to move this line here, which obviously is part of the geometry associated with the original associate dimensions, so I'll click there on that line, right click and just use my AutoCAD Move command again to pick on the top corner there, left click and just drag that to the right by 200 millimeters. I'll put 200 in there and press Enter. Notice this line here is moved by 200 but so has this line because it's maintaining the 1800 dimensional constraint. So as you can see there, those dimensional constraints, useful. More importantly, you can convert existing associative dimensions to dimensional constraints.
