Watermain Coverage Solu-Around

This solu-around provides a very efficient solution for checking the minimum coverage along the entire length of watermain . This could also provide an easy way to design watermain if utilized correctly.
The overall goal is simple. Copy the existing ground profile to a minimum depth.  
A few simple steps are provided.
1.Create a profile over alignment (pipe run). 2. Select existing ground surface in profile view and use the AutoCAD copy command to duplicate it. 3. Select new existing ground profile, select profile propertie and name it Watermain minimum coverage and set a unique profile style.
4. Select new profile, right click and select profile properties. Navigate to the Profile Data tab, and move the scroll bar until update is located. Change the watermain coverage profile to static.

5.Select the profile and notice all of the grips that are highlighted. The profile is no longer dynamic to the surface. Now we are able to move the profile down to check for minimum coverage.
6.With the profile selected pick geometry editor. Locate the raise lower PVI icon and select it. Set this to the depth required for minimum coverage. Make sure you specify a negative number.

 Two profiles should be showing.

Adjust the pipe to make sure it is below the new surface.


This concludes a simple watermain solu-around.

Corridor Driveways, Sidewalks and ADA Ramps - Autodesk University 2010 ONLINE

Autodesk University was great. Had a lot of fun in VEGAS, it’s like a play ground for grownups. If you were unable to make the conference this year check it out online. All classes are available for FREE if your company is on subscription. Autodesk University Website

Please check out my class this year and classes I did previously.

Endless Corridors with AutoCAD® Civil 3D_ CV422-2 -2010
Diversify Visually with Autodesk Civil 3D_DV322-1 - 2009
Don't be left out in the CODE_CV9314-1 - 2009

The most prolific topic that I discussed was utilizing Conditional Subassemblies, ConditionalHorizontalTargets to complete driveways, sidewalks and ADA ramps. Below is an example of how this works.

Plan view results applying one assembly. Notice the curb is removed from the drive ways, and the sidewalk continues through the walk, but is removed from the road. This is accomplished by simply placing polylines at critical locations. The conditional subassemblies have an option to look for the nearest or the farthest target and associating the correct subassembly. The red polylines placed on the driveway applies the gutter subassembly and the green polyline marks the target for where a region should be placed so no subassembly is applied. More elaborate subassemblies can be developed to utilize conditional subassemblies after each individual subassembly. Have fun and remember to place and test the targets are working, before applying the no target subassembly.
Review the class for further details on this concept and unique way to handle intersections

Compose subassemblies visually for FREE

Check out the latest in Autodesk Labs and the best part, the software is FREE. This tool was deleloped to modify or build custom subassemblies without .NET knowledge.


The technology preview release provides a strong set of subassembly functionality for corridor modeling:
■ Define points and position them based on several positioning methods.

■ Define links between points.

■ Assign codes.

■ Define targets and input parameters.

■ Specify conditions for daylight and simple expressions.
