does anyone know if its possible to create a drawing without a
part? I mean like floorplans and more civil
engineering drawings ? I have tried by first creating a sketch
but later I could not open a sketch in a drawing.
you can do 2d "sketchs"/drawings using the lines, circles, etc, in drawing mode. make a new drawing, without a model in session, and you are good to go. If you have models in session, just go in to the drawing options and delete the model . Hope that helps.
Well, I suppose it is always possible to use a model.
Take your sketch and extrude it with some improbably small thickness,
say 1" on a 100' x 50' bldg. Then you can use your relations and
sketches and all the other power of pro/e that I miss so much now that
I'm stuck in AutoCR*P hell.
N.B.: You might have to fiddle with thickness and global accuracy to keep pro from complaining every other regen.
Just make sketched datum curves or cosmetic features. Then you have a parametric model without solid geometry. But really, if all you want are 2D floorplans, etc., Pro/E is not the best tool for the job.
