The bulbs are all on and I have history at the bottom, but at this point I don't really care which process I'm in (I've used SW &amp; SE), I'm fine with constraining the dimension of the solid part or the original sketch.&nbsp;</P><P>&nbsp;</P><P>When I right click on the timeline and select edit (which is showing up now but wasn't earlier) it puts me into sketch and shows the sketch lines, but not the dimensions. If I select Dimension from the drop down menu it won't allow me to dimension it as it then says it's overconstrained.</P><P>&nbsp;</P><P>If I left or right click on the surface 'Dimension' isn't one of the options (I presume because I'm in historical mode?). So how do I edit the dimension of the inner face?</P><P>&nbsp;</P><P>Thank you.&nbsp;</P><P>&nbsp;</P><P>Edit: Okay, there are three sketches, I'm not sure why, they don't highlight anything when I click on them, the first one highlights and the dimensions showed up and I can edit. I'm not sure what the other two sketches are, I've deleted them and nothing changed on the model.&nbsp;</P> Mon, 02 Feb 2015 06:21:52 GMT Anonymous 2015-02-02T06:21:52Z
