Creo10 drawing: cross section radius annotation of a ''round''

PC98 — Mon, 23 Feb 2026 13:42:44 GMT

Hello,

I have a cross section of a radial pump rotor with radiuses which I want to annotate the standard way with arrow and ''R8'' written for radius of 8 mm.

I can do that to other curvatures, but not to to the surfaces made by feature ''round'' that are made on vane endings.

I tried with ''show model annotations'' but there I can find these annotations being scattered elswhere to unwanted positions. Can not move them to cross section by ''edit attachment''. Whenever I click the curve that represents cross section of a round to insert ''dimension'' nothing happens- no dimension is written and no arrow shown. Same happens for any other similarly created rounds in this cross section.

Despite round being defined as round of 8 mm, I can not measure it with ''measure'' tool. What is the way to annotate such rounds on cross sections while keeping them dependant on radius defined in ''round'' feature?

Best regards!

Without the actual model, it's difficult to tell for sure. I would guess that that radii isn't "true" in that view so creo won't allow the attachment.

As a test, If you can add a created radii dimension to that view, then that would tell you if it if a true radii. If you can't, its not true to the view. Your options are limited if its not a true radii. One way would be to create a view that shows the radii as true. In a jam I will make a label note and use the radii dimension in the from the model in the note, at least its still a real dimension that drives the feature you are pointing to.
