How to fix “Please delete the latest coping object” Errors in Advance Steel

We get this question a lot in support where someone is getting errors in the command line saying that a cope cannot be processed and not know how to fix them (example shown below):

In most cases, having one or two of these errors will not inhibit your ability to work in the model or create drawings. However, if these errors build up, the model will experience performance issues, so it is always good to clean up errors when they are found. Here is how to find the specific object/cope (be sure to clear marked objects before starting this process):

1. Under the Advance Tools Palette, go to the Selection panel and start the Mark object tool 
2. Press H to input the handle.
3. Type the object handle for the error message. For example: 881 based on the 1^st screenshot.
4. Look for the marked object; use the Search marked object or Zoom to marked object button to make it easier to find the object in large models: 
5. Check the object for incorrect / invalid features and fix them

If you cannot see what is wrong with the object, you can repeat this process but use the feature handle to directly select the incorrect / invalid feature (ex. 9D9 based on the 1^st screenshot). The word “cope” in the error includes not only copes, but basically any feature that cuts an object (ex. holes, shortenings, etc.). After you mark the feature, it will not change its color to red, but it is marked. You can use Select Marked Objects to select the feature and then delete it. Most of the time, these features are invalid and will not change the shape of the object, but it is best to double check if the feature needs to be recreated.
