Change the boundary of the cut lines of a model element in a view.
This video demonstrates the following:
Use the cut profile tool to make small modifications to model elements when you need to illustrate something in a detail view but is not necessary to model.
For example in this detail we want to illustrate the keyway between the concrete foundation wall and the foundation element. The keyway was not modeled because it would not be visible in the model, will not significantly impact material takeoffs, and only needs to be shown in this one foundation detail. In this case creating the keyway will be most easily accomplished with the cut profile tool.
On the View tab click "Cut Profile". Now select the model element you want to modify, in this case the wall foundation. The boundary of the object is shown in orange.
In the sketch mode make the alterations to the cut profile. The end points of the cut profile sketch need to lie on the boundary of the model object. The first segment of the cut profile sketch will have a small arrow indicating which side of the cut profile will be kept when the sketch is completed. In this case we have sketched the portion we want remove. Click the arrow to change its direction to keep the larger portion of the foundation. Click the check mark on the ribbon to complete the sketch.
Now the cut profile of the wall base is altered to fit the keyway cut out we just added to the foundation.
Additional detail elements complete the condition needed for the detail.
Using cut profiles to illustrate conditions in a detail can save time when building the model of your project. Consider using cut profiles when appropriate when detailing in Revit.
