How to add dimensions to model to retrieve them in the drawing

[Anonymous]

I have been reading here that the preferred mode of generating dimensions on the drawing views is by using "Retrieve" method. My question is: how can I programatically add dimensions or measurements to the model so I can retrieve them in the drawing view? This has to be all done by code.

The model dimensions that can be retrieved in drawing are sketch DimensionConstraint/DimensionConstraint3D, and FeatureDimension. To add the sketch DimensionConstraint/DimensionConstraint3D you can use PlanarSketch.DimensionConstraints.Addxxx and Sketch3D.DimensionConstraints3D.Addxxx, and for feature dimensions they will be created when you create a feature. But not all the dimensions can be retrieved into a drawing view, you can use the GetRetrievableDimensions to check if a dimension can be retrieved into a drawing view. Hope this clears.
