Walk Through a Topo Survey

Navigation: Learning TPC >

We like to say that in TPC - Surfaces are Wickedly Simple. In this walk through, we'll show you why.

•each step has a short video – some are a little longer

•see how TPC creates a surface for a Site - Topo survey

1: Topo Project Introduction (6:12)

•this is a Site, Topo survey for an architect

•we’ll show you what we delivered to him, including the surface

2: Source, Border and TIN (5:50)

•We use a traverse as the source

•Turn topo designation on/off for individual points

•TPC creates a default border that you can override

•TIN – model the surface with minimal points

3: Adding Breaklines (1:40)

•Breaklines help you better model the actual surface

•Import traverses to define breaklines

•You can also edit breaklines manually

4: Slope Analysis (1:56)

•You specify the slope ranges and fills

•TPC computes the total area for each slope range and shades them in the drawing

•You can print a summary of the slope analysis plus add ranges to the legend
