Annotation Scale Crisis
I’ve had a few staff here complaining of very slow opening times for CAD drawings, and also huge delays when copying/pasting between drawings. In the worst cases this wait has grown to 10mins or more, which isn’t particularly productive.
It seems the problem caused by a huge annotation scale list that builds up exponentially in LT2008 when you start xrefing drawings. Overlaid xrefs cause the same damage, and detaching them doesn’t take away the annotation scales they brought in. You soon end up with thousands of scales and the drawings are near-impossible to work with.
This problem may be encountered by anyone, but it is only caused by 2008 versions of cad that haven’t been upgraded with service pack 1.
- To fix this, start off by installing Service Pack 1 - this will prevent the problem reoccurring once the drawings are sorted out. It’s on both our servers ready to install, and only takes 2 mins. Alternatively download it here.
- Clear out the redundant scales in each drawing by entering the “-SCALELISTEDIT” command. Choose ‘Reset’ and ‘Yes’. Or
- For batch clearing of entire affected jobs, use Autodesk’s ‘Scale List Clean-up Utility’ to reset the whole lot back to match our template. See Andy (Stokesley) or myself (Leeds) for a hand doing this.
Once everyone is upgraded with the service pack we will never have the problem again. Hopefully.
