 SSA Important Import Eccentricities

There are two very important import eccentricities in particular that need to be mentioned. They are not show stoppers but are essential to be aware of:

  • Storm Sewers Migration Defaults (Pipe Networks-Feature Settings)

The following is not an eccentricity but a must do: Do select your Part List Used for Migration. Civil 3D will look to this list for parts when importing and exporting STM files.

Summary

Here is the eccentricity: When configuring you Part Matching Defaults, after you hit the ellipsis to choose a part, Civil 3D will show you ALL the part families in your PART LIBRARY, not just the ones from your PART LIST. 

If you do by mistake select a part that is not on that part list, it could result in your parts not exporting correctly to the STM file and not importing at all into Civil 3D. So be familiar with your default part list for migration to avoid this issue.

  • Imported Pipe Network Names Change

This will happen when you import more than one STM into SSA then export the project to one STM file. When the overall STM file is imported into Civil 3D, it may offer to override the first or primary pipe network imported into SSA. However, the remaining or secondary pipe networks will come in under arbitrary names.

Tool space

The workaround is to delete the networks with the arbitrary names if the master STM was already imported, and give the secondary networks the new names that are coming in from the master STM file.

Pipe Network Properties

The secondary networks can be renamed back to their original names if needed.

AUTOCAD CIVIL 3D TIP: HOW TO CREATE RETAINING WALLS

Image
  Smart Retaining Walls I've seen a couple of different ways people use to create retaining walls in Civil 3D.  More times than others, I see people creating a grading group representing their retaining wall, generating a surface with it, and pasting it into their site surface.  It generates contours which is the desired result.  This is a fairly quick and simple method. I prefer to create a more BIM-like retaining wall with a retaining wall assembly.  My reasons for using this method are: Retaining wall assemblies recognize when they are in cut or fill and will shift codes around accordingly. Retaining wall subassemblies have adjustable parameters. Retaining wall code sets can be applied which not only affect the display of the wall in plan and model, but apply elevation labels automatically in section. The top of the retaining wall can be controlled with a profile which makes it very easy to visualize and design the top of the wall in comparison with a surface.  Also, when the pr

AUTOCAD CIVIL 3D - GRADING

Image
Heads Up Grading for Parking Lots In the good ol' days, before data collectors were in wide spread use, we used to get our existing topo on paper. We'd have to throw it over a big ol' digitizing board and trace it with a puck. This was referred to as digitizing which was a very time consuming task. Later, we were able to have the paper scanned, insert the image into AutoCAD, scale it up, and trace it on screen. This was referred to as "heads up digitizing" which was a lot more efficient and faster. I've coined this term "heads up grading" for those who give up the paper, scale, and calculator way of grading to use the grading tools in Civil 3D instead. The example presented in this post will show how quickly and efficiently one can arrive at a grading solution using this method.  If there are any fundamental concepts in this post that you do not understand, please refer to  Mastering Civil 3D by Richard Graham & Louisa Holland .

AUTOCAD CIVIL 3D TIP: HOW TO ADD NEW PIPES TO PRESSURE PIPE CATALOGS

Image
  Pressure Pipe Networks are fairly new to Civil 3D, and anyone who has worked with them has noticed that Civil 3D only comes loaded with ductile iron piping as an option in the parts catalog. Whether Autodesk adds more piping materials to the standard catalogs in future releases remains to be seen, but most users would like to see a PVC parts list at the very least at some point. As for now, there are options to buy pre-made parts lists from private companies, but they can cost thousands of dollars. A more affordable option to those who really only use a handful of pressure pipe sizes/materials is to build your own, and import them into Civil 3D. No special software is needed, and a basic pipe size can be created and imported in a matter of minutes. Creating fittings and appurtenances is a bit more involved, but that will be covered in the next tip. Here are the steps for importing new pipe materials and sizes: 1) New Catalogs and pipes can be added very quickly through the Content Ca
