Dimension lines won't attach

[drguitarum2005]

Afternoon yall,

I came upon a weird problem today. I have made thousands of sheet metal parts and their associated drawings without issue but this time, I made a part and attempted to make a drawing but dimension lines won't attach to certain geometry in the drawing. It acts like it will until I click the second line for the dimension then it errors, telling me the same error message that comes up when you delete a feature that previously had a dimension.

I also can't place an origin for doing a hole chart, for example. It just turns purple and says it isn't attached even though it clearly is.

Any ideas?

Thanks.

Edited to add .ipt file too.

Using your dataset in a full up to date version of Inventor 2014, it works just fine on my PC. It doesn't sound like it would be the issue, since as your post reads, you have successfully selected the first line. But have you checked your selection filters are set to Feature Priority?

I tried all the various priority options and nothing changes. I am also running a fully updated 2014 and still can't dimension this drawing. I deleted the drawing and make a new one and still have a problem. I restarted Inventor, my computer, etc. and no luck. Why would it tell me my dimension lines can't be attached if it allows me to click the line to start the dimension as normal? Thanks for your help,

Have you tried opening up a different drawing? Is it possible that one of your keyboard keys are stuck? For instance, one of the ctrl keys?

[drguitarum2005]

It's only this drawing that's affected. It's like there's something it can't resolve in the geometry of the model but it's not a complicated piece really you know?

Try right clicking on one of the views, then go to general dimension type. Is 'projected' selected or is 'true'?

[drguitarum2005]

It is set to "Projected". To be sure I set it to "True" then back to "Projected", no change

Is it only the flat pattern view on sheet 2 that this is a problem on? Because there are like 3 spots on that view where I can't get it to select a point for me, but I can snap it to a line no problem.

Maybe when in dimension command, right click and uncheck all the snap settings, then go back and recheck them? Because when I did this it started letting me select those points it wouldn't let me pick.

[drguitarum2005]

Yes it is only the flat pattern view for some reason. I unchecked all the snaps and re-checked them and still no dice

It's because your faces actually touch (see attatched pic).  Just make it so there is a gap inbetween them and the problem goes away.

[drguitarum2005]

Thank you! I actually thought about that but figured that wasn't it since I was having trouble with lines that had nothing to do with that area but sure enough, that fixed it. It's weird because when I make things touch like that using other methods, Inventor cries about it and I scale it back by .01 inches or so. This time it let me so I didn't even think twice about it.

Thanks again!

It's nice to be appreciated.
