You have more than one client, each with their own drawing standard, border and style. How do you set up Inventor to handle it?
In short: you have to use Projects and the Style Editor, and optionally Application Options, depending on your setup.
Set your Project so that it uses a different folder for the client (red arrow in dialogue window below). I usually create a subfolder in the default location (see the last section of this document for information about the default locations) under Design Data with the client’s name as the folder.
When you do this the first time, Inventor will ask you if it can populate the new location (folder) with the required files. Click Yes. Note that Use Style Library is set to Read-Write in the project setup.
Create a folder in your default template location where you can save your new template file(s). I usually create templates of my IPT and IAM files too, so that I can enter specific iProperties relating to the client's requirements (BOM/Parts Lists will almost certainly differ from client to client). All your templates for the client should be saved in this new folder. When you start a new file, you’ll have something like this:
I usually put the client's name in front of the default names that Inventor gives to the files (obfuscated in the figure above).
If you now click on Manage, Style Editor, you’ll be able to create a new Standard or change one of the default ones to suit your client’s requirements, as shown below. If you do make changes to a Standard (a modified or new one), remember to save the changes (you can right-click and save).
This is set in Tools, Application Options, File tab, as shown below.
