Feature Creation: Exercise Revolve - setting diameters

jel111

I am trying to set the Diameters for this drawing and cannot for the life of me figure out how to set the diameter to the angled line. I have all the constraints set like the exercise drawing and all the other dimensions seem ok. The only one I can't get to pick up the diameter dimension is the angled line. I'm wondering if there is a way to set this in the text box? It would be great if you could write "2.75 dia". Here is what I have.

dimension from one of the outer points of the angled line to the centerline. If you do that, and take the mouse to the other side of the centerline, you get the option to make the dimension diametric instead of radial.

I actually tried that, I tried the middle construction line and the bottom one. I tried deleting some of the constraints thinking maybe I added the wrong one. I tried to start with that measurement first before trying to add any others. I tried adding the measurement above and then tried to add that measurement. I tried redoing the construction lines. I also started from the beginning with a new drawing and got the same result. I don't know what I am doing wrong but I am going to continue with the tutorial and maybe I will figure it out eventually. Thanks for replying I really appreciate it.

Oh I was looking at it wrong. the diameter of that seems like it's already set to 1.5. If you want to set the thickness of that area, just pick either of these edges with the dimension tool. you don't need to pick two things. If it's something else, then you've lost me, haha.

What Evan is saying. You have other dimensions fixing the end point of the line.

It's the way that the tutorial tells you to do it. I tried deleting that dimension and adding a radius again for the lines below with no luck.

Not sure which tutorial your looking at but the sketch looks quite busy and perhaps over loaded.
Try removing the 0.626 length dimension applied diagonally along the line that ends where Evan has high lighted.
It looks like it has fixed the point at the end.
Changing between radius and diameter will not change the point you're looking at.
If you still can't figure out then you might want to make your document public and paste link here.

i'm late to the part but this stumped me for an hour or so. For he angled line i had to click the point, click the horizontal construction line, then drag it under the construction line. I assumed since i couldn't do that with he other lines it wouldn't have worked with the angled lines.

A trick to help diagnose problems like this, is to click and drag on any blue lines and try moving them around slightly to see if they behave properly. Most of the times you will quickly see what is generating the issue (i.e. bad constraint or hiding dimension). Once you locate the issue it's relatively straight forward to solve the problem.

Sorry this is not case specific, but it is a good general rule to follow in the future.

Good luck

I've had trouble with "center-line dimension to a point" before, and found that it can be order sensitive - try changing the order of selection (point first or center-line first), yeah I know it sounds silly, but it's tripped me up before.
