In PCB-Investigator there are many options to edit or set the PCB-Outline/Profile:

1. Set by Rectangle: This allows you to draw a rectangle with your mouse cursor

2. Set Rectangle by Selection: It creates the profile around all selected objects, this is always the bounding box rectangle

3. Edit Profile: this opens an extra dialog similar to surface edit in the edit dialog

4. Set by all Objects: sets an rectangle profile around all objects

5. Get Bounds: This show a message box with the size and offset of the current step

6. Clear Outline: With this button you can clear the outline and remove all existing profile elements.

7. Add active Layer(s) to Outline: You can add the active layer to the profile, be carefull maybe you have to Clear Outline first.

8. Add Selection to Outline: By selecting important objects like drill holes or routings you can add them to the existing outline.

9. Create Layer from Outline: This create a new layer with lines and arcs on it to export or modify the profile, if you use Add active Layer(s) to Outline (7) after Clear Outline (6) you can use the modified profile

10. Set from Selection Middle: to use online the middle of your selected lines and arcs you can override the existing profile e.g. by an routing way

11. Add from Selection Middle: this is the same like 10 but do not override the existing profile, it only adds the closed way in the selection

12. Set from Selection Holes: with this option you can use only the inner area of an routing way or a hole in an surface for the profile

13. Set PCB Outline: this allows you to define the profile with many mouse clicks
