Dimension line in Creo drawing

Hi,

can someone help me in how to represent the semi circle dimension line in creo drawing.

PFA of the image below.

Re: Dimension line in Creo drawing

There is no such dimension that I know of. It really doesn't make any sense, anyway. The value of the dimension is entirely dependent on whether it refers to the inner edges, the outer edges, or the "centerline" of what seems to be a tube. If the last one is what you are after, you could calculate the "chord length" using simple relations, then use the calculated value in a note.

Hi Kenneth,

Yeah it semi circular tube. In the previous auto cad drawing they have represented end to end tube dimension in that way.

If its not possible to represent in that manner, how can I represent the semi circular tube dimension in Creo drawing.

Kindly help on this.

Re: Dimension line in Creo drawing

The last sentence says "...calculate the 'chord length' using simple relations, then use the calculated value in a note".

In other words, use the relations functionality of Creo to calculate the length of the tube in the same way you would by hand.

For example, if you assume the centerline length of the tube stays the same before and after bending, and the u-shaped section has a straight length of "L" and a centerline bend diameter of "D", you can create a parameter called "LENGTH" and calculate it as:

LENGTH = 2 * L + PI * D / 2

Then create a note, and in the text of the note put something like "TUBE LENGTH REQUIRED: &LENGTH".

The &LENGTH will be replaced in the depiction of the note with the calculated value.

Re: Dimension line in Creo drawing

you can also use perimeter dimension

Hi Kenneth,

can we not have any option other than providing note to represent the dimension in the drawing.

Interesting. I wish I'd known about this particular dimension type when I was defining O-ring grooves in the past. Could also be useful for timing belts and such.

Re: Dimension line in Creo drawing

If I absolutely NEEDED to show it on a drawing, I would sketch it either in the drawing or as a curve in the model. I would add a note that uses a driven value maybe like Kenneth shows or a perimeter dimension like Pushkar shows.

There is no way to simply do this in Creo.
