How many of you wish there was the ability to put a revision cloud on a change on a drawing in Inventor? Me too. I have been working with Inventor for a long time and didn't know this was available at all. There is a way to install some usertools that will allow you to be able to create revision clouds on drawings.
Follow the steps below to install the tools:
First open a windows explorer page; and put the path below into the address bar.
Once you are in that folder find the file that is called UserTools.msi; double pick on this file to run the installer.
be sure that Inventor is closed when you are doing this.
Once the installer is done...boot up Inventor and open a file. Then go to the add-ins tab, and wallah...there you have the ability to create revision clouds.
