It's possible to dimension diameter on section D480 (pic1), and thread (pic2) without using fake dimension. My thread symbol is constantly on the projection full circle, even when in customer defaults I change to 3/4 circle.

For the first issue, if you can include either a 2D or 3D Centerline in that view, you can select it and the dimension should double if you're using a Cylindrical dimension. You may have to enlarge your view boundary and/or make the 2D/3D Centerline view dependent (expand the view then insert 2D/3D Centerline, expand out of the view, create dimension, fix view boundary).

Not sure what your question is with the second issue. Are you trying to change the display of the threads? If so, that may be a part specific setting meaning only new parts will be affected by changing the customer defaults. You'll have to change that via the View Style/Settings dialog. Do not forget for a change in customer defaults to take effect, you must restart NX for it to take effect. If you're using a template, changing the customer defaults won't have an effect on the template file.

Thank you,my second question is how in section I can dimension thread.I only see this option as hole callout in radial dialog for threads in view.Here is for NX 9,same is for NX8.5.

What I want is this

There's a 'Hole Callout' option available with liner (Horizontal or Vertical) dimensions as well.

Cylindrical dimension can't do this, it gives only dimension value between two points.

I beg to differ... it has always worked for me as long as the centerline is picked first and the edge of the cylinder second.

@ewh


I tried that and it did work, except when the centerline is outside of section boundary.D302,1 is the true diametar.Thank you all very much.[cheers]

There may be other issues involved, as I am able to get true diameter dimensions using a centerline within the same view and the edge as well as using centerlines from other views (as long as it represents the same axis and orientation).

I guess, I will have to stick with the centerline within the boundary. There could be the issue with my NX since D296,7 doesn't have any sense.
 
First You have to create centerline of hole. Use 3D centerline which will automatic place in center of hole. Then You have to choose cylindrical dimension. Next select centreline and second edge of hole. You should receive something like on Your last picture, first section. Then select this dimension, right click style, go to dimension tab and deselect left | and lest arrow. You should get diameter like on first picture in this thread.

The Centerline can be View Dependent if you do not wish to see it. The View Boundary can be set to manual and you can hide it after placing the dimension.

Here's a video if anyone wants to see what I mean by making the Centerline View Dependent and adjusting the View Boundary.

Or you can just create and name the centerline in modeling under properties
and then you can reference it in drafting as your first pick without
going in and out of view dependent edit.
 
Here's a word document on how to dimension using a named centerline.
This is for NX8.5 and earlier. From NX9 and beyond it's a totally
different process using a "name selection" box and a few other different things of course.
