Notch tab

Use the Notch tab to automatically create notches for the secondary beams and to control the notch properties. The Notch tab has two sections: automatic properties (top section) and manual properties (bottom section). Automatic and manual notching properties work independently from each other.

Automatic notching

Automatic notching options affect both the top and the bottom flange.

Manual notching

Use manual notching when a part that does not belong to the connection clashes with the secondary beam. When you use manual notching, the connection creates cuts using the values you enter in the fields on the Notch tab. You can use different values for the top and the bottom flange.

Side of flange notch

The side of flange notch defines on which side of the beam the notches are created.


Option	Description
	Default Creates notches on both sides of the flange. AutoDefaults can change this option.
	Automatic Creates notches on both sides of the flange.

Option	Description
	Default The entire flange of the secondary beam is cut as far back as you define. AutoDefaults can change this option.
	Automatic The entire flange of the secondary beam is cut as far back as you define. The default depth for the notch is twice the thickness of the secondary flange. The cut always runs the entire width of the secondary flange.
	Creates chamfers in the flange. If you do not enter a horizontal dimension, a chamfer of 45 degrees is created.
	Creates cuts to the flange with default values unless you enter values in the fields 1and 2.
	The flange is not cut.
	Creates cuts to the flange according to the value in the field 1 to make it flush with the web.
	Creates cuts to the flange according to the values in the fields 1 and 2.
