If you select them all, you can edit their width and height in the Properties window. It can be useful for the tool to leave some tags during the Profile operation.To do this, right click on the Profile operation and choose "Add Tags".
You can then click on each of the places that you want the tag. You should place your tag within a tool radius of the tool path, otherwise the tag will be ignored.
The tag objects will be added in the Objects window, under a Tags object.
When the g-code is created, you can see that the tags cause the toolpath to raise up at the point where the tag is.
