Always wanted to get started in Autocad to make your own layout files?
This weeks tip gets you started in Autocad and this is an example of an easy way to create your first layout file.
In this weeks tip we will create a new file, import a pdf floor plan, place points and draw lines in AutoCad to export to your survey equipment.
There is a free course offered by Construct-Ed called Layout Part One: Establishing Elevations, its a free course that takes you through the whole process of understanding decimals to shooting elevations. There is also a quiz at the end, click this link Layout Part One: Establishing Elevations to start the course!
•Set up tripod
•Set & level
•Find a benchmark
•Place grade Stick on benchmark
•Shoot grade stick to determine elevation above benchmark.
•Determine the height of your instrument (HI)
To find your HI (height of Instrument)
Start from a benchmark-Known elevation point + measurement on grade stick
IE: benchmark 4320 + 5.80 (decimal Stick)
Your HI= 4325.80
If your building datum elevation is 4320 (which is equal to level one finish floor)
then 4320= 100.
If your HI is 4325.80 this equals 105.80, so you are 5.80 above finish floor.
If you are trying to establish elevation, lets say 105.00 on core walls for reference. Then you would shoot a mark on the wall (this is level with your instrument) and measure .80 (9-9/16”) below the mark to be at elevation 105.00.

Using a decimal stick is quicker to convert numbers vs. using feet and inches stick.
A cheap calculator and to know decimals is all you need to make elevation layout a breeze. (need inches to decimal converter: click here)

This week's tip we will show you how to quickly and simply overlay drawings in Revu. We will take a footing plan and overlay it with an underground plumbing plan which makes it helpful to see everything on one page in the exact location to help you plan your workflow, recognize sleeve location and elevations and find any conflicts. This is just one example but you can overlay any drawings on your project with Bluebeam.
