When we first started using Plant3D here were I work we were unaware that dimensions on orthographic drawings don't update with objects that are changed or moved. I was told that they DO update now in 2014 by one of the trainers from Imaginit. I just want to confirm that this is true and that dimension DO update now in Plant3D 2014. Any insight would be great. Thanks in advance for any and all comments...
By "Not yet" are you assuming that it is comming soon? Maybe a service pack or the next version? If you seach "about dimensioning" in the 2014 help, it makes it sound like it does...
About Associative Dimensions
Dimensions can be associative, nonassociative, or exploded. Associative dimensions adjust to changes in the geometric objects that they measure.
Dimension associativity defines the relationship between geometric objects and the dimensions that give their distance and angles. There are three types of associativity between geometric objects and dimensions.
You can determine whether a dimension is associative or non-associative by selecting the dimension and doing one of the following:
A dimension is considered partially associative when only one end of the dimension is associated with a geometric object. You can use the DIMREASSOCIATE command to reassociate non-associative dimensions.
Associativity between a dimension and an object may be lost for several reasons. For example:
You can use the annotation monitor to track leader associativity. When the annotation monitor is on, it flags dimensions that lose associativity by displaying a badge on the dimension.
Before update event
After update event
Clicking a badge, displays a menu that contains options specific to the corresponding disassociated annotation. The menu on a dimension that has lost associativity provides access to the DIMREASSOCIATE and ERASE commands.
Special Situations and Limitations
You might need to use DIMREGEN to update associative dimensions after panning or zooming, after opening a drawing that was modified with an earlier release, or after opening a drawing with external references that have been modified.
Associative dimensions support most object types that you would expect to dimension. They do not support objects such as
Dimensions associated to model drawing views may lose their associativity if the drawing is opened and re-saved in a pre-2012 release of AutoCAD.
I know it's an often-requested item on the wish list. Obviously, not being Autodesk I can't say when it's going to happen.
The help file section you reference is from standard AutoCAD, and associative dimensioning for standard AutoCAD objects was created a long time ago.
The trick in this situation is that Plant uses blocks when generating these orthos. In addition, when you re-generating a viewport, the old blocks are wiped out, and completely new ones are created.
B/c new items are created, the dimensions no longer remember what they were tied to, and do not stretch or change to make model changes.
Thanks for you help Dave and the clarification. It just seems kind of crazy to me that Autodesk would put out a product that has such a huge flaw like that. It has to bite people in the **** all the time. I just don't see how every little change that happens could be noticed and caught every time a drawing gets updated...
