I would like to add the material specs as custom properties of the material so that hey come up accurately on the drawing. Currently the material spec is a custom property in the part. The disadvantage is that it needs to be entered separately from the material so it does not always get done accurately or the spec property in the model does not get updated when the material for the part chnges. Apparently these can only be accessed by using a custom API program. Has anyone written an API to do this?
