I have modeled a chair in Solidworks, and have used various surfacing techniques, with drafts, curves etc. which add complexity to my model. See image attached.
Now that I am in edrawings trying to add dimensions to my models there a certain curves which I cannot define - and I am sure this is common and thus there must be a work around. For example, the radius on the front, top edge of the arm (right elevation) cannot be defined. Another example; I cannot define the height of the chair (maybe something to do with it being a thickened surface?). How do you define such difficult dimensions?
Note: The shell of my chair was created by first creating a 10 degree drafted extruded surface from an open profile (the bottom left edge; I then drew the profile of the chair on the right plane and used it as a split line to cut my extruded surface.
Thanks

You are doing what I have had to do at times also. Something that helps in some cases is to place construction lines in the drawing which can often constrained with tangent relations to the edge of some curves. Dimensions to splines and 3D-curves can be tricky. Split lines can be helpful at times also. You are correct in your thoughts about the use of the 3D Model to reduce the dependence on the drawing dimensions. We place a note on the drawing stating that the dimensions shown are largely for reference and the model should be used for the details.
