You can edit styles in the User category, which duplicates the entire Advance category. After editing the User category, the original styles from the Advance category can be reused.
When editing a drawing style or when adding a completely new one, it is recommended to use Copy (not Deep Copy), and reuse as many sub-functionalities as possible.
All the existing rules, views, and presentations are reusable, so any edit can affect other drawing styles. When editing or creating copies to start the work, never edit without creating or copying a rule and be sure to minimize the amount of copies, reusing as many existing settings as possible.
The following image highlights the layout structure of a drawing style:

Selected model objects, presentation and labeling strategies are core settings which directly communicate with Advance Steel, while the upper settings in the tree are saved rules that reuse certain configurations. Editing any settings of an existing drawing style requires a set of copies of the rules that are above that respective setting, including the drawing style itself.

Here is a set of steps required to edit an existing drawing style. You create a copy of the drawing style and its hierarchy so none of the existing drawing styles that reuse the respective settings are modified during the process.
As an example, modify the assembly part drawing style for a plate and its connected anchors. You can allow anchors from a trimmer plate to appear on the part drawing for annotation
The drawing style in this example is the 5-Plate assembly, from the 5-Assemblies category.
For this example, you need to modify the Object presentation rules for all the views in the drawing style to add the missing anchor object.
The workflow for adding a new object in the Object presentation rule for anchor detailing involves the following modifications to the drawing style hierarchy:
The modifications will need to be copied to ensure that no other styles are modified.


(Add a new object presentation). This will add a new line at the bottom of the list, containing values copied from one of the existing entries (generally the first line is copied). The object presentation rule will contain a duplicate entry. The new line will store the necessary modifications to add the anchor object to the plate drawing style. You can reuse existing configurations to add the anchor as they are core settings which do not require a copy.



Following the steps above, the drawing style displaying anchors will be part of the user detailing database. It is created with only a small number of copies (5 in this case), with everything else being reused. This allows for a small database and avoids introducing unnecessary duplicates.
