swats Posted October 9, 2012 Posted October 9, 2012 The company I work for recently started getting into designing and building weld fixtures. Over this past weekend I worked from home on our first fixture project. I used ordinate dimensioning on my most of the detail drawings. The issue I had yesterday was that when I opened the drawings in my computer at work some of the ordinate dimensions would move, and display a different dimension value. Has anyone seen this kind of behavior? What causes it? How can I fix it? The details are 3d models and dimensioned in paper space. Thanks. Quote
ReMark Posted October 9, 2012 Posted October 9, 2012 Did you lock your viewports? Did you make you dimensions "associative" (not the same as "annotative"). Did you have PERSPECTIVE enabled or disabled? Quote
swats Posted October 9, 2012 Author Posted October 9, 2012 Viewports are locked. Dimensions are associative. Perspective is turned disabled. This behavior happens on my work pc, and on my co-workers pc as well. I have not seen it happen on my pc at home. For more information. I am using Autocad 2012 at home. At work we are using 2005 and some 2010. Drawings done in entirely in 2005 have shown this behavior in the past. Therefore I have kind of avoided doing ordinate dimensioning unless really necessary.

ReMark Posted October 9, 2012 Posted October 9, 2012 I have no clue then. Kind of why I never dimension 3D models. I extract the 2D views and dimension them instead. Quote
swats Posted October 10, 2012 Author Posted October 10, 2012 I have an idea of what might cause it. I remember years ago when I was still doing mostly 2d drawings, I would see this same ordinate jumping behavior when opening some drawings. We use a lisp program for bringing in dimension styles and layers. When you open a drawing that that has been purged a dialog box pops up telling you which layers are missing. I wonder if that could be the cause. Quote
ReMark Posted October 10, 2012 Posted October 10, 2012 Only one way to find out...test the theory. Report back here with your results. Quote
swats Posted October 11, 2012 Author Posted October 11, 2012 Well I took some time to do a little experimentation. I found a drawing that I had worked on this past weekend where a few of my ordinate dimensions would move. I went into appload to disable the lisp program that we use for creating are dimension styles. I then restarted autocad, and then checked to make sure the lisp program was not loaded. Next I opened the drawing that I found earlier that showed this behavior. This time a few of the dimensions still moved. I guess that kind of eliminates that idea. I then looked at the dimensions to see which ones are associative. The ones that are associative are the ones that moved. The dimassoc variable for that drawing is set to 2. I wonder if that might be the issue? Quote
ReMark Posted October 11, 2012 Posted October 11, 2012 If the dimensions are associative then wouldn't it stand to reason that the dimensions would move when the geometry changed? I have DIMASSOC set at "2" as well. The dimensions physically changed position or did the values change? Quote
swats Posted October 13, 2012 Author Posted October 13, 2012 The dimensions physically moved. The dimension value changes to represent the new position. I did not change the model geometry. Quote
ReMark Posted October 13, 2012 Posted October 13, 2012 It is difficult to come up with an explanation as to why entities would physically change position on their own thus leading to changes in dimensions. These are 2D drawings we are talking about right? Quote
