using constraints in autodesk autocad 2015

I have a profile view (cut with Civil 3D) at a scale of 1:1 so that we can design this without having to worry about an exaggerated scale. Drawing the Criteriaīelow is our area of design. 2D geometric and dimensional constraints to the rescue. But, in the real world, the existing ground will vary, the depth to the pipe will need to be adjusted, and the deflection angle will need to follow this adjustment.

Now, in an “orthogonal” world, this wouldn’t be that difficult as you could simply have a block that has these deflection angles. Note though that the entrance and exit can be swapped based upon the existing conditions on either side of the road. So, looking at the diagram, we can see that the standards call for a range of deflection angles for the entrance and exit of the pipe. The diagram below shows the design standards that we must follow for this project

Instead, we will propose borehole construction which will dig a hole underneath the road using a casing pipe that will carry the utility pipe. The specific example I will cover here is for constructing utilities under a major road or highway where we cannot dig a trench due to the high volume of traffic on the road. (And be sure to check out my Tuesday Tips article with an overview of 2D constraints.) Borehole Construction In this post, let’s look at a real-world example of using constraints that really saves you a good bit of time and automates a workflow that aids you in designing. I sometimes think it is because they can’t think of an everyday use for them. Solving all of the workshops will simulate the creation of three projects (architectural and mechanical) from beginning to end, without overlooking any of the basic commands and functions in AutoCAD 2015.AutoCAD has had 2D geometric and dimensional constraints for a while, but most drafters don’t leverage their functionality in everyday use. AutoCAD 2015 Beginning and Intermediate includes over 100 exercises or “mini-workshops,” that complete small projects from concept through actual plotting. Use the DVD to set up drawing exercises and projects and see all of the book’s figures in color. Covering all of the 2D concepts, it uses both metric and imperial units to illustrate the myriad drawing and editing tools for this popular application. This book is the most comprehensive book you will find on AutoCAD 2015 – 2D Drafting.
