Tip of the Week #53 - Undefined in Corridor Template Instruction

Blog Post created by Matt McLean on Aug 27, 2018

Hello folks and welcome to the reading of another TBC Tip of the Week. Thank you to the very knowledgeable Alan Sharp for this tip, he sure knows TBC!

 

When modelling and creating a corridor in TBC, it is common for many templates to be used. Would you believe me if I told you most corridors can be modelled with just one? There is a trick to this! (Hint, it’s using the ‘undefined’ (?) character in template instructions)

 

Here I have created a corridor using an imported alignment.

Alignment

 

I will now create a template using Corridor > Corridor > Insert Template with Begin station: 0+00.00.

Insert Corridor Template

 

In the Edit Corridor Template command pane, Under Offset/slope from: select 1 > HAL (HAL is my alignment name). This selects the start point for the instruction to be referenced from. Under Offset: select Table.

Edit Corridor Template - Create Instruction

 

Select the three ellipses to open the table.

 

I filled the table out as below. For the pavement of my corridor, I want a gradual change from 0’ from the alignment to 12ft from station 1+80 to 2+20. I want a 12ft width until station 3+00 where I have an intersection and want to have a gap in this template. I want the template to resume at station 3+80.

Instruction Table

 

I set the Slope % to -2.00% and named the instruction EOPR (Edge of Pavement Right). Click Add.

 

The instruction is shown on the plan (and 3D View). Notice the use of the ‘undefined’ (?) character has created a gap in the instruction in the template. This allows the input of repeating sections of a corridor quickly and easily.
