Dim to theoretical intersection

[bill.costello]

Hi
I know a lot has been mentioned about this subject, but I was playing around in an idw today, and I kept forgetting the method of dimensioning to a theoretical intersection.
I came across this by accident.
in the attached jpeg, I dimensioned the horizontal line, then simply dragged either endpoint (green) of the dim and whilst dragging, hovered over the endpoints of the angled line and the horizontal line, moved my cursor over near the thoretical pont and the two dotted lines appeared, then the yellow dot appeard denoting the exact point, dropped the dim on it and hey presto it worked. (JUST LIKE AUTOCAD, Acquiring tracking points)
Not trying to teach anyone to suck eggs, but just hadn't seen it done this way before, and I can remember this easier.
It even puts the apparent intersection point markers.

regards

Bill

Like I said, no eggs, didn't realise it was there.

I agree. Nice find.

Somewhat OT: Dennis, I followed the link to your tutorials. That page is a little confusing because the pointer changes to a text cursor rather than a 'pointing hand icon' when you hover over the links. (At first I thought there were no links).
Also, the link to the home page at the bottom is broken due to a typo.

Thanks,

I'm working on a fix..

What if you have a surface that's an arc with an intersecting straight surface and there's a fillet where the two surfaces intersect. When I try to use the dimension to a theoretical point by right clicking "intersection" and digging on the arc and the straight surface, it won't pick up the theoretical point. I tried using Bill's approach too, and it won't work either. My boss told me if I can't dimension to the theoretical point, he's going to fire me and sue me for incompetence and derrilection of duty. Help!

Thanks,

Can you post the part and idw, zipped?

As a work around I have used a sketch to give me an intersection I could
dim to. Make sure you select the view before you start the sketch so it
will be linked and you can project the edges to constrain your sketch.

If you haven't, try using "sketch dimension" when dimensioning?

[Anonymous]

That is one of the retarded limitations of Inventor. As a work around you
should create a sketch in the view and dimension to the sketch point. It is
very "convenient" and "logical" indeed!

Don't take this the wrong way but, why are you dimensioning to there? There are a couple of different way you could dimension that which, while having the huge advantage of not being hard to do, also seem (to me at least) to make more sense. Of course, I don't know how you will make this or what it is used for.
