“How to fix a drawing with callout of <MOD-DIAM> instead of the DIAMETER symbol”
When updating to a newer version of SOLIDWORKS sometimes you will start seeing issues with your Diameter
symbol not showing when you create a Diameter Dimension. Instead you will see <MOD-DIAM>.
This issue can happen for a couple of common reasons. The first scenario is when your GTOL.SYM file does not update properly during a software upgrade. The second scenario could be when you installed your new version of SOLIDWORKS, there was a complication during the install and your GTOL.SYM file was never installed and so it is missing. The third scenario could be that your new installation of SOLIDWORKS is still looking to an older version GTOL.SYM file. The final scenario, this behavior can occur if you use the Copy Settings Wizard from an older version of SOLIDWORKS and import the settings into a newer version of SOLIDWORKS.
If you are experiencing the Diameter Dimension behavior from either scenario one or two, then Solution 1 described below will help fix the issue. If you are experiencing the behavior for scenario three and four, then Solution 2 described below will help fix the issue.
The first step is to see what could be causing this issue. To do so you will need to access your Symbol Library File under Options>System Options>File Locations>Symbol Library File. From there you will see where SOLIDWORKS is looking for that GTOL.SYM.
The next step is to open up a new Windows Explorer Window and browse to the folder location. Typically the Program Data folder is hidden, you will need to adjust your system settings to show hidden folders. Once you are able to view the Program Data folder, navigate to the GTOL.SYM file.
SOLUTION 1: For Scenario 1 and Scenario 2
If the GTOL.SYM file is missing you will need to get a copy of this file from a coworker or you can ask for it from DDI Tech Support. Once the GTOL.SYM file is transferred to that folder directory, try creating a Diameter Dimension to see if the issue is fixed.
SOLUTION 2: For Scenario 3 and Scenario 4
If you look at your system options and see that SOLIDWORKS is still looking to an older version SOLIDWORKS folder, you will need to adjust your system settings to look to the latest version of SOLIDWORKS in your Program Data folder. You will need to delete the existing file directory from your SOLIDWORKS system options, then add the new file location.
(Navigate to the desired file directory in Windows Explorer Window before deleting current path in SOLIDWORKS. This way when you add the new path for SOLIDWORKS it will be easier to locate.)
Start with removing the old:
Then click the add button to add the new location:
Here it is with the new location:
After adding the correct File Location, e.g.,“C:\ProgramData\SOLIDWORKS\SOLIDWORKS 2016\lang\english\” of your GTOL file, try to create a Diameter Dimension to see if the symbol appears.
