Diameter dimensioning in the Certification training tutorial… how did they automate the "Ø" in the challenge exercise?

Diameter dimensioning in the Certification training tutorial… how did they automate the "Ø" in the challenge exercise?

I'm referring to the Autodesk tutorial on this webpage (link). I've attached the two .dwg files, starting file and finished file, my version and the PDF instructions.

I understand how to get the "Ø" symbol come up when I select a circle it happens automatically. Or I can use the Diameter option in the DIMS command. But in this instance the drawing is indicating diameters of bore holes on a section drawing, so they shown as rectangular shapes, no circle to prompt Autocad into using the Diameter option for the Mtext.

I used a work around, creating a new style based on standard and putting the 'Ø' char as a prefix on all dimensions. But in the finished file they didn't do that. How did they do it?!

———————
Also I had a second issue trying to make the workaround style for angles to remove the incorrect inches unit symbol (") suffix from the dimension style (this is something that wasn't required, the instructors ignored this as an oversight i expect). I'll post a separate thread on that and link back to it here later.

Hi @alastair_leith ,

 

Yes, you can create additional Dim Style for such Lind of dimensions, but in the "finished" version they used dimension text override method:

Select the dimension in "finished" version of the drawing and look at the Properties Palette:

The dim text is: %%C<> - this means that diameter symbol - %%C - added to the default text - <> 

 

You can remove " from the angular dimension also by editing properties of the individual dimension (remove " from the prefix):

Thanks @maxim_k

I may as well post my other issue in this thread.

I tried to make an Dim (sub) Style based on the Standard DIM style to do all angle dimensions (to remove the inches unit) but when I set "use for" to "Angular Dimensions", perplexingly, it wont let me edit any of the parameters for primary units other . Same for Radius and Diameter sub-styles. Seems very counter intuitive to my intuition!

Hi @alastair_leith ,

 

You can use command line version of DIMSTYLE command to create separate sub-style for angular dimensions.

Ensure that current dim style is STANDARD.

Start with changing DIMPOST System Variable to none - type point when AutoCAD prompts for DIMPOST value:

Command: DIMPOST
Enter new value for DIMPOST, or . for none <""">: .
Command:

 

Now use command line version of DIMSTYLE command (with dash before command name) to save new dim style with special name "Standard$2":

Command: -DIMSTYLE
Current dimension style: Standard Annotative: No
Current dimension overrides:
DIMPOST
Enter a dimension style option
[ANnotative/Save/Restore/STatus/Variables/Apply/?] <Restore>: S
Enter name for new dimension style or [?]: Standard$2
Command:

 

Now use command line version of DIMSTYLE command again to restore Standard dim style:

Command: -DIMSTYLE
Current dimension style: Standard Annotative: No
Current dimension overrides:
DIMPOST
Enter a dimension style option
[ANnotative/Save/Restore/STatus/Variables/Apply/?] <Restore>: R
Enter a dimension style name, [?] or <select dimension>: Standard
Current dimension style: Standard Annotative: No
Command: 

 

Now use dialog based version of DIMSTYLE command to see the changes, you should see:

Thanks @maxim_k . is your solution a work around to a bug in the Dialogue version of DIMSTYLES? Seems like a lot of hoops to jump through when the GUI should be able to do it.

Should I log a bug about this on the Autodesk Community Council?

This is not a bug, but a feature.

This has always been the case in AutoCAD.

If you need different settings for different type of dimensions in one "master" dim style, you need create base style, then create individual sub-styles from it, then edit each of sub-styles.

 

In your case you can at first remove " suffix from the "Standard" dim style, then create Linear and Angular sub-styles, then edit Linear sub-style and add suffix to it.
