Pros and Cons of LiDAR

When it comes to capturing existing conditions, the first question in everyone’s mind seems to be “to scan or not to scan?” With all the technologies out there, the next question is usually “which tool is best for the job?” Complicating the ability to answer these questions is the accelerated pace at which new technology developments and commercially available products enter the market.

When overwhelmed by choices—especially new, unproven and expensive options—we’re often moved to inaction, making it difficult to invest in the proper technology. But if we don’t invest now, we will fall further behind our competitors.

During the last couple years, we have invested in a wide range of reality-capture technologies ranging from traditional, ground-based survey tools to terrestrial laser scanning to unmanned aerial vehicle (UAV)-mounted capture platforms. We now find ourselves flying drones on jobs that previously may have been captured with terrestrial-based scanners. Drones seem to captur…

Express Yourself: Using Expressions in Civil 3D

Expressions in Civil 3D have been around since the beginning of time……Civil 3D time! However, I don’t think people utilize expressions to their full capabilities, or even at all.I’ve heard of some pretty cool ways people are using expressions to label and analyze their models in Civil 3D and thought I’d share a few.
This article helps walk through setting up a couple expressions, starting with simple mathematical formulas to more advanced analysis expressions.
About Expressions Expressions are stored in the Settings tree, within the label style type folders. They are not available for label style types that do not have relevant properties, such as Note label styles.But for the most part, they are available in every type of label such as surface, alignment, profile, etc.
You insert expressions into label styles using the Text Component Editor when you are editing a label style text component.

Expressions make use of the same properties that you can add to label styles, such as Point Elev…
