Al,
Sorry thats the only way I can create that scenario. The only other 2 thoughts that I have are: Tools>Options>sketcher>the constraints checked (see Jpeg)
or the create datum toolbar is activated (the lightning bolt)
Sorry Hope you figure it out...
AL,
while in sketcher under the sketch tool bar make sure your
dimensional constraint toolbar is on.http://files.engineering.com/getfile.aspx?folder=fad84a5a-7ebe-4250-affe-6956b4e1f183&file=SKETCH_TOOLS.JPG
