Converting Civil 3D objects from Imperial to Metric (and vice versa)

This post is about the conversion of Civil 3D objects from Imperial units to Metric units. Of course this exercise can be reversed to convert from Metric units to Imperial units.

For this exercise I use the LandXML (version 1.2) Import and Export Tool.
Some characteristics of LandXML in short:

Launched January 2000, LandXML.org is committed to providing an non-proprietary data standard (LandXML), driven by an industry consortium of partners.

See for more information: http://www.landxml.org/

The exercise:

  1. Open the (or a) drawing with Imperial units.
  2. Go to Toolspace, Settings tab, and select the Active Drawing.
  3. Right-click on the active drawing and select Edit Drawing Settings.
  4. Check if the Drawing Settings are in Imperial units (Feet).
  5. Go back to Toolspace, Prospector tab and right-click on the active drawing and select Export to LandXML.
  6. Choose the latest LandXML version 1.2 and select the Civil 3D objects to export.
  7. Choose a apropriate file name and click OK.
  8. Now open a new drawing (template) with Metric units.
  9. Check if the Drawing Settings are in Metric units repeating step 2 to 4.
  10. Go to Ribbon, Insert tab and click LandXML.
  11. Select the earlier exported LandXML file and click OK.
  12. Choose the objects to import, accept or change the import settings and click OK.
  13. See the results (the imported objects) in your drawing window and in Toolspace,the Prospector tab.
  14. Check with the Measure inquiry tools if the objects are converted correctly.

There are a lot of applications right now who have the LandXML import/export supported.
And lots of them are Autodesk based. Take a look at this blog of Jeremy Tammik about the API of Revit and a ‘script’ how to import LandXML data into Revit. The sample program shows a way to import surface data from Civil 3D through LandXML into Revit. See: http://thebuildingcoder.typepad.com/blog/2010/01/import-landxml-surface.html

Another conversion tool is the GENIO Import/Export tool from Autodesk. With this tool you can import from MX Roads objects (features) to Civil 3D objects and vice versa. A short instruction can be found at the Autodesk website, Services & Support, Civil 3D, Documentation, under the Skill Builders.

Copy and/or Paste Surfaces

I’ve looked for an explanation or instruction of how to Paste Surfaces in AutoCAD Civil 3D.
I have several sources available to me to start with. The following 4 textbooks and 2 eLearning modules about Pasting Surfaces in AutoCAD Civil 3D I’ve read:

The textbooks:

  1. Digging into AutoCAD Civil 3D 2010 (Rick Ellis)
  2. AutoCAD Civil 3D 2009 for Engineers (Prof. Sham Tickoo)
  3. Mastering AutoCAD Civil 3D 2010 (James Wedding/Scott McEachron)
  4. Learning AutoCAD Civil 3D 2010 (Autodesk)

The eLearning sites:

  1. eLearning (4D Technologies via AUGI website)
  2. vBooks (via APW-CTS)

The textbook Digging into AutoCAD Civil 3D 2010 was the only one of the 4 textbooks that gives me an example how to Paste a Surface into another first by copying the Surface with standard AutoCAD commands. Which leads to several cautious steps to take before acting the actual Paste Surface command. This will also lead to that the copied surface doesn’t have any (dynamic) relation with its source surface anymore. So changes made to the source surface will not automatically change the newly created and pasted surface.
The textbook Mastering AutoCAD Civil 3D 2010 was the only one how to Paste a Surface the right way.

Both the eLearning sites give an explanation of Pasting Surfaces but only one gives more meaningful but short explanation on how to use it. The one from 4D Technologies (Wendy Miller speaks) is good enough as an example how to use it right.

So here’s Wendy Miller’s instruction: (For author protected reason’s I make use of other materials).

Case: Say for example you have a Existing Ground Surface (EG) and a Pond Surface (Pond) made of grading feature lines. You want to make a new Finished Ground Surface (FG) with the Pond surface (Pond) pasted into it but leaving the EG surface compleet as it is.

  1. Create a new Surface from the Toolspace, Prospector and name this surface FG. Use the Suffix “-*” to create this surface on a spearate layer.
  2. Go to the Prospector tab and expand the newly created surface FG, go to the Definition part and right-click on Edits, and select Paste Surface
  3. Select the Existing Ground (EG) Surface, and click OK
  4. The newly created Finished Ground (FG) Surface now has the EG surface copied into it.
  5. Now go again in Prospector to the FG Surface, Definition, Edits, Paste Surface and select the Pond surface,
    and click OK.
  6. Now the Pond surface is pasted into the FG surface.

This way you’ve created the new Finished Ground (FG) surface derived from the Existing Ground (EG) surface and pasted the Pond surface into it.
The FG surface will dynamically update when either the EG surface and/or the Pond surface are changed.

If you want to make individual surfaces which are not linked to one another then you have to make use of the AutoCAD copy command to duplicate the surface and rename it to FG before pasting the pond surface to the copied FG surface. But then again you have to make sure to freeze or thaw all needed layers in this procedure to get a good visual from what you’re doing. And I even don’t have to mention the AutoCAD copy command which could lead to a (say even the smallest) displacement of the copied surface from the source when done wrongly.
This way the FG surface is not dynamically connected to the EG surface but only the Pond surface is dynamically connected to the FG surface.

Adding extra search paths to the Printer Configuration Search Path

This blog is about a question from one of the members at the LinkedIn Group “AutoCAD Civil 3D Workforce”. 

The question was: “Is there a way Civil 3D is able to search for two locations to look for PC3 files”. 

This is more a standard AutoCAD question and is the same for all the other AutoCAD vertical products like AutoCAD Civil 3D. 

Using AutoCAD in a networked environment, it’s common and desirable to separate the enterprise settings from local (adjustable) settings as far as AutoCAD allows you to configure. This is the same for the Printer configuration files (.pc3) where you as a CAD administrator or CAD manager want to centralize the plotter configuration files preventing from being changed by users and therefor losing all the effort and time you put in to harmonize these settings. You could create a front-end batch mechanism to copy all centralized plotter configuration files to the home user folder, but keeping those files up to date is time consuming and can result in differences of the configuration. You don’t want that. 

There is a way though to separate centralized Printer Configuration Files from the local user Printer Configuration Files.
The behavior of the Printer Configuration Search Path setting is to search for all files in the assigned folder.

Figure 1. The Printer Configuration Search Path in the Options dialog menu

But there is more to this: it will also search for all files in all sub folders.

In above example if you create a sub folder in S:\Map3D2007\Plotters and place other PC3 files in that sub folder they will also show in AutoCAD.
As for a CAD manager and for maintenance purposes you could setup several sub folders for different kind of clients or projects, just to separate them from the company ones.
For example:
S:\Map3D2007\Plotters    ‘The location for all company configured PC3 files’.
S:\Map3D2007\Plotters\ClientA    ‘The location for all configured PC3 files used for Client A.’
S:\Map3D2007\Plotters\ProjectX    ‘The location for all configured PC3 files used for Project X.’ 

All PC3 files in above (sub)folders are located on the server and are visible in AutoCAD. If setup correctly these files should be configurable only by the CAD manager and not by the user.
Now if you want the user also to be able to add his/her own Printer Configuration Files, create a folder shortcut from the user’s home folder and place this in the assigned Printer Configuration Search Path folder.
This user folder can reside on the local hard drive or even better on a small shared folder on the server only accessible to the user. Every good CAD manager or IT administrator should setup the user’s Home folder for all users the same with identical folder names for everyone to find or to recognize. 

Figure 2. The Shared Folder on the Server and the Folder shortcut

So placing a folder shortcut in this shared folder will result also in a search within the folder shortcut as if it resides below the assigned folder in the Printer Configuration Search Path. Because of this link to the user’s Home folder, its content is fully accessible and configurable by the user. This way the user has (read-only) access to all centralized Printer Configuration Files managed by the CAD manager as to those in his/her Home folder. The ones residing in his/her own Home folder are configurable and managable for him/her only. Don’t forget to place a copy of the Add-A-Plotter Wizard in this user’s Home folder so he/she can create their own Printer Configuration files.
At the end all (separated) Printer Configuration files are available to you in AutoCAD as if they all reside at one location. 

Figure 3. The User's Home Folder from which the Folder Shortcut will be created. Figure 4. The Properties of the created Folder Shortcut.

Figure 4. The Properties of the created Folder Shortcut

 The beauty of this behavior is that you can put as many folder shortcuts as you want in the assigned Printer Configuration Search Path folder. 
And last but not least:  this trick will also work for the Plot Style Table Search Path.
