CAD Standards are meant to be changed. They are not to be created and set up as if chiseled in stone tablets. They should be reviewed and updated on a regular basis. I keep a Master copy of the Standard that I mark up and then publish when there are enough changes to make an impact.
When should you upgrade the standard? Here are some suggestions…
- When a new release of software comes out and you need to add standards for new tools
- When some part of the standard is flat out wrong
- When some part of the standard needs to be clarified because the standard was silent before
- When it has been so long that no one remembers the last time it was updated
While I encourage the update of the standard, I also encourage you not to update it too often. If you put out updates every month or two, then people will get frustrated that they cannot keep up with the changes.
It is a balance that you need to determine for your own environment. Each office may need a different timeline.
