Add Snipes to Steelwork Members

MDS provides the ability to create and modify snipes on support structural members. A snipe is where a support structural member is cut at an angle, such that a corner is removed.

This feature currently only works with angular sections, i.e. steelwork profiles of type SCTN and gtype ANG. Two cases are catered for:

•

Snipe on end of leg attached to stiffener

•

Snipe on free end of section.

Snipe on End of Leg Attached to Stiffener

When the section is attached to a stiffener the following calculations are used, where


	SL =	Snipe length on the leg of the framework
	FL =	Length of leg section
	M1 =	Control gap for back-to-back (default = 10 mm)
	M2 =	Length in the opposite direction of M1 on flange of stiffener
	M3 =	Distance between flange top outside edge of stiffener and leg point connected with the flange top of stiffener (default = 25 mm)


When L > M1 + FL + M2 and M2 >= 25mm, Snip is not provided on support leg as below.	When L > M1 + FL + M2 and M2 < 25mm Snip is to be provided on support leg as below

When L =< M1 + FL and M2 (=M1 + FL - L) =< 0 (zero) mm Snip is to be provided on support leg as below

Snipe on Free End of Section

When the section is not attached to a stiffener the following calculation is used:
