Alert! Egress Path on Fire

EGRESS-PATHThis is a trick I made for documentation of egress paths and checking egress travel distances in life safety plan.

How It Works

By clicking a number of points on floor plan, I can create the egress path with the egress travel distance automatically measured.  Tagging the path with a generic model tag will report out the total egress travel distance.  If the egress travel distance exceeds the maximum travel distance (by code and set up by user), a fire symbol will pop up to alert me that the plan doesn’t work.

Construction

This is a generic model adaptive component family.  An adapative component allows you to free hand draw a series of lines by clicking to locate points at several locations.  In this case it is a 12 point adaptive component which allows drawing  11 segment path.

EGRESS-PATH2

12 points were created at arbitrary locations and made adaptive.  Every two adjacent points were dimensioned and made reporting parameters (L1, L2, L3…).

EGRESS-PATH3

A parameter “Egress Travel Distance” was created to total all reporting parameter (L1, L2, L3…).  The starting dot and the ending arrow are 1 point adaptive components adapting to the starting point and the end point.  The Building Code has the maximum travel distance defined.  A type parameter ” Max Travel Distance” was created, it was made as type for different jurisdiction having different requirement.  The fire symbol is another 1 point adaptive component.  The fire symbol was placed and its visibility was controlled by a parameter “Alert”.  The “Alert” parameter was related to the “Egress Travel Distance” and “Max Travel Distance” with this formula: Egress Travel Distance > Max Travel Distance

EGRESS-PATH4

Similarly I can create a number of these egress path families (2 points, 3 points, 4 points …) for paths with different number of segments.
