Dimension commands in Sketch/Modeling

Is there a reason, why there is no Ordinate dimension in sketch?

And the same goes for Symmetric Diameter (Solid Edge term). This is the dimension, that is very useful in revolve object. When you wnat to dimension over the axis. So, that you are not dimensioning radius. Instead, you are dimensioning the diameter.

 

And by the way.

How do I change the name, that is displayed for me (SvenBom)?

 

Thanks.

Re: Dimension commands in Sketch/Modeling

being new to NX form SE, we're really missing the Symmetric Diameter dimension. is the a simular command in NX?

While not exactly the same, this allows you to dimension diameters:

- Draw all curves on one side of CL (no need to constrain/dimension)

- make sure there's something along the CL (I use a line converted to "reference")

- (NX7.5) there's a drop menu on the toolbar (usually defaults to "Offset curve")
   One of the options under it is "mirror curve" - select that

- pick your curves to mirror

- pick CL

Done - dimension diameters as desired

 

Of course, it may be easier to just enter the sketch dimension as "diameter/2"

Hi Stephen,

 

according to the subject of this thread, you are talking about Sketch dimensions, right?

 

There is no Dimension type in NX, that is a real equivalent to the "Symmetric Diameter" in NX. I would like to see that too for creation of rotational parts, but it is not available now.

 

So for rotational parts, you usually use radius dimensions and rotate one half of the sketch section 360 degrees. To apply diameter dimensions, you can use a formula (parameter=diameter/2) for each dimension or mirror the geometry and convert it to reference geometry.

 

see attachment (NX8.5).

 

Note: Using my example part: If you delete the dimensions, and use auto-dimension, symmetries are recognized and diameter-like dimensions are auto-created.
