Transcript of How to use TBC to create an accurate 3D surface model

Data Prep Process:
Thoroughly read through plan set and specifications
Import data (preferably a CAD file but a vectorized PDF works as well)
Clean-up imported data
Organize data
Edit linework
Create additional linework and points to supplement provided data
Elevate pertinent objects, linework and points
Check the prepared data for accuracy
Create a 3D surface using the data you just prepared
Importing Data
For model building - we'll be importing the following types of data regularly:
CAD Files - Generally the best source of starting data

PDF Files - Geo-reference and Scale capabilities within TBC

.csv or .txt Files (point files)



Clean-up Imported Data
Project Clean-Up command - quite possibly the single greatest tool for data prep.

This quickly eliminates unwanted objects, deletes duplicate objects, joins lines, converts CAD lines to linestrings and more.

The operator sets the parameters for each function of this command - giving total control to the user preparing the data
Organizing Data
View-filter manager - allows user to isolate only the layers needed at the moment to clarify the data set
Delete empty layers
Explode blocks
Create new layers
Rename existing layers
Name objects in the properties pane to assist field personnel
Change layer settings to more clearly display data
Editing Linework and other Objects
Break lines
Delete line segments
Trim/Extend lines
Join lines
Move objects
Rotate objects
Scale objects
Create Additional Lines, Points and Objects
Copy objects
Offset lines
Track region outline
Create points
Create linestrings, polylines and alignments
Elevate Data
Set line elevations
Change elevations
Elevate contours by label
Elevate contours by crossing
Elevate contours individually
Elevate Lines
Elevate Pads
Edit Linestrings (Vertically)
Edit Points
Check Data for Accuracy
Explore object
3D View - orbit around a focus point
Properties - review any object's data by looking in the properties pane.
Model's Complete!

How to create a surface model utilizing Trimble Business Center
....and gain essential project information!
Vector Graphic
An image that is composed of shapes defined by points and lines. These points and lines are able to be imported by TBC to provide 2D objects based on a PDF site plan.
Creating a 3D Surface
Create Surface
Add/Remove Surface Members
Add/Remove Surface Boundaries
Trim Surface Edge
Create Surface Tie
Merge Surfaces
Drape Objects on Surface
Create Breaklines
Create Cut/Fill Maps
Create Surface Elevation Grids
Use Flags Pane to identify conflicts.
Use Surface Slicer View to check for Accuracy!!!
