Edit Cut Profile: Using the Edit Cut Profile tool (Part 3 of 4)

The main lesson to learn about the use of this tool is that you cannot change, edit, cut, split, etc; the original boundary profile itself. What I mean is, the actual line itself that you now see highlighted on your screen cannot be altered. BUT: What you can do is ADD an area to that profile OR SUBTRACT an area from it.

To try and explain what I mean by all this I have produced 3 sketches which should clarify matters:-

The original element

Here is an original element before we modify the cut profile. The element’s original cut profile is represented by the red line on the left hand sketch. The hatched area on right hand sketch represents the cut area.

Cut area ADDED to original

You will see on the left that we have increased the cut profile by sketching lines to enclose an additional area. Note: We do NOT (nor cannot) alter the actual original boundary lines (shown red)- but we do not need to- Just adding an additional boundary to the original will result in a new cut area as shown on the right.

Cut area SUBTRACTED from original

Once again, the original profile boundary remains unchanged. We sketch lines in the inside of the original boundary to tell Revit what cut area we want to subtract. This results in the new cut area as shown on the right.

What we can learn from the three sketches above:

• The original profile boundary is not (in itself) ever altered.

• The modifying boundary that we sketch MUST connect with the original boundary at it's TWO ENDPOINTS
