Continuous and Baseline dimensions have been streamlined in AutoCAD 2014.
Autodesk created a new System Variable: DIMCONTINUEMODE. It determines whether the dimension style of a continued or baseline dimension is inherited from the dimension that is being continued or from the current dimension style.
Initial Value: 1
In previous releases of AutoCAD if you had an existing dimension and wanted to create a Continuous or Baseline dimension from it, AutoCAD would automatically use whatever your existing dimension style was.
For example, if you create a new dimension style based on an existing and you just make something kind of dramatically different on the new dimension style – change the color or maybe the text height, which is a noticeable change. Then you set that new dimension style current.
In previous releases of AutoCAD there was no DIMCONTINUEMODE variable, which is new in AutoCAD 2014.
If you set DIMCONTINUEMODE system variable to 0 (zero) it will behave like in previous releases of AutoCAD. If you create a Baseline or Continuous dimension using an existing dimension, AutoCAD automatically uses the current dimension style.
That’s really not what you want. Typically if you create a Continuous or Baseline dimension, you want it to look like the existing one. So you’ll erase that and set the new System Variable then continue mode back to its default which is 1.
The behavior of AutoCAD 2014 is that you create either a Continuous dimension or Baseline dimension by selecting an existing dimension. AutoCAD will automatically use the same dimension properties as the one you selected regardless of the current dimension style.
