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

Posted by Matt McLean 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.

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

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.

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.

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.

# Tip of the Week #52 - Creating a Point On-Line Between Two 3D Points

Posted by Matt McLean Aug 17, 2018

In many situations it is useful to create a point between two 3D points, with an interpolated elevation and a desired horizontal offset from one of the lines; here's how that can be done easily and efficiently!

I have two points separated by 141m horizontal, 10m vertical. In the plan view I have the point elevation displayed.

Short version:

Create Linestring between the two points. (direction matters)

On the Edit ribbon, use the break line command.

Create a point at End of line. (In Create Point drop-down)

Detailed version:

First is to Create Linestring between the two points, starting from the point you want to set the offset distance.

I have drawn the line from point 1 to 2. After opening the Create Linestring command, you can press "Enter" to skip the first menu, and go directly to selecting the start and end points of your line. After clicking the two points, pressing "Esc" twice will exit the command.

Next, go to Edit > Lines > Break

Select the line (if it's not already), and enter the distance along the line you would like to create the new point. (This is why the direction the line was created matters) I would like my new point to be 50m from the start point.

Hit Break or press "Enter" on the keyboard.

Next, CAD > Points > Create Point (select the drop down) > End

Select the end of the broken line, and click Add or press "Enter". A point will be created here.

If the linestrings are not desired, they can be deleted.

And there you have it!

# Tip of the Week #51 - Quick Zoom Extents

Posted by Matt McLean Aug 10, 2018

Hello fellow TBC’ers! Happy friday!

Short and sweet one this week for you folks, I learned this myself recently and hopefully it soon becomes common knowledge!

When navigating the plan or 3D views in TBC, often it is useful to use the Zoom Extents command on the View ribbon, but moving the mouse to the top left corner of TBC takes just as long as zooming out using the scroll wheel. Fear not! There is a shortcut to Zoom Extents which will always be in reach.

Simply double click on the scroll wheel of your mouse, and TBC will Zoom Extents. The 3D view will maintain the angle with which you are viewing your data when you double click the scroll wheel.

# TBC August Power Hour Announcement - Processing Delair UX11 Aerial Data in TBC

Posted by Joe Blecha Aug 7, 2018

Happy to partner with Delair and announce the TBC August Power Hour on August 29th...

Processing Delair UX11 Aerial Data in TBC

Unmanned aircraft systems (UAS) have rapidly worked their way into the geospatial industry as useful and economical technology for data collection. With the increase of solutions on the market today, selecting the right hardware, processing software, and workflow for your needs is not always easy, but critical to your success. This month’s TBC Power Hour session will show how pairing Delair’s UX11 UAS hardware with the processing and deliverable capability from TBC is a viable, streamlined, and familiar solution for your UAS surveying needs.

# Tip of the Week #50 - Graphic Selection Methods

Posted by Matt McLean Aug 3, 2018

Good day Ladies and Gentlemen! It’s Tip of the Week day, I hope this excites you as much as it does me! An aside before we dive in: A study was published in the Journal of Science last week by a team of Italian researchers, they have compelling evidence that liquid water exists under the poles of Mars. I think scientific developments like these are so cool. Find the study here: http://science.sciencemag.org/content/early/2018/07/24/science.aar7268

When selecting points, linework, and objects within TBC, did you know the direction the selection is made affects the way objects are selected? This can be done in both the Rectangle and Polygon selection modes.

Rectangle Select can be selected in two locations by default, in the quick access toolbar at the top of TBC, and on the “Data” ribbon under Select.

To select only objects completely contained by the rectangle, drag from left to right. Below, only the lamp post CAD object and the two points, 1050 and 1051 are selected.

When the rectangle select rubber band is drawn from right to left, any object partially contained within the rectangle will be selected as shown below. The selection area is shown with a dotted line to indicate it will select objects partially contained. In the same selection area, this time from right to left, the linework of the parking lot island is also selected.

The Polygon Select command can be found right next to the Rectangle Select command in both the quick access toolbar and “Data” ribbon under Select.

The Polygon Select command has similar functionality to the Rectangle Select command. When the selection area is drawn clockwise, only objects completely contained are selected. When the selection area is drawn counterclockwise, any object partially contained is selected.

Click and drag to start the polygon select command. Insert additional vertices by clicking, and double click to finish drawing the polygon.

As seen below, when drawing the polygon in a clockwise direction, only objects completely contained are selected.

When the polygon is drawn counterclockwise, any object partially contained is selected.

Here two very different polygons can be used to select this group of CAD tree objects.

I hope you enjoyed this week’s tip of the week, and hopefully this helps to streamline your day just a little bit more!
