Subassembly Studio by CADArtisans allows you to create custom .NET parametric subassemblies for AutoCAD Civil 3D.  This subassembly show in the video was created using Subassembly Studio V1.04 from Cad Artisans (www.cadartisans.com)

This subassembly consists of a fill slope that intercepts a target surface. If the horizontal distance from the insertion point to the intercept point exceeds a user-specified MaxWidth, a retaining wall is inserted at the MaxWidth and the slope is reconstructed to target the back of the retaining wall. This subassembly was created in approximately 8.5 minutes from start to finish, including importing into AutoCAD Civil 3d and inserting into a corridor model.

The primary strategy when creating subassemblies is to first create the positions and behaviors of points.  The links are defined next from a list of points.  The shapes are defined from a list of links.

Autodesk has created a video outlining ways you can improve the performance of Civil 3d 2011.

I compiled a short list of software manufacturers offering point cloud software.  The race is on to see who can come up with the best modeling tools to transform a point cloud into intelligent 3d data.

Sure there are more great contenders out there.  I got you started.  It’s your turn..go find them.

ViewCube Rotated

Type in PLAN and then choose W for World coordinate system.  Crosshairs look great.  UCS Icon looks perfect. ViewCube is rotated a little bit.  Why?   

I figured it out about 2 months ago then ran into the same problem today.  Could not find any of my notes on the solution. I checked every system variable I could think of.  Clicked on the Top hot spot on the ViewCube and the orientation of the ViewCube changed to due North as it should.  Now the crosshairs are rotated.  OK, I’ll spare you the rest of the agony I went through.  

Type 

GEOGRAPHICLOCATION
  

 

A dialog box appears offering a few choices.  Choose Edit.  The North direction setting should be zero.  If not, your crosshairs and UCS Icon are not aligned with the Compass on the ViewCube. If you never intended to have a geographic location setting for the drawing you can choose Remove.  

 

In this post I want to show you that exchanging data between Civil 3D and Carlson Survey is relatively easy.  I made two posts today about transferring data using LandXML.  Additionally, in this blog post at Carlson Connection  you will find that working with Civil 3D data in Carlson/IntelliCAD is not such an impossible chore.  Carlson Survey for example has a command to convert a Civil 3D or Land Desktop surface to a Carlson TIN file.

Civil 3D – Land Desktop – LandXML Version Matrix

When converting Civil 3D data back to a previous version using LandXML it is important to use the correct version of LandXML.  This table will help you choose the correct output format.

A quick presentation of transferring points and a surface model from Carlson Survey to Civil 3D using LandXML.

Note: In the last part of the video the presenter edits an existing surface style making it look harder that it actually is.  A style to display contours is already defined in Civil 3D’s drawing template you simply change the style from a drop-down list in the surface properties instead of digging into the guts of an existing style to change settings.

The NPR program Science Friday had a segment on the brain’s ability to multitask. The conclusion is that the human brain is not very good at multitasking, in fact what happens is you simply jump from one focus to another. I think this subject is very relevant to performing CAD tasks. You need to put aside distractions to be more effective at CAD.  Listen to the segment and see if this changes they way you work.

Do you have a need to create a folder with the current date as the folder name?  I create a “Received” folder in each job folder structure.  When I get new files I put them in a subfolder with the current date formatted as 2010-05-27 so they sort chronologically. 

I do this so often that I wanted to put a command in Windows Explorer that would create the folder for me automatically.  Now, I can browse to any folder, right click on a folder, and pick the command New (DATE) Folder.  No typing, one click and it is done.  To add this command to the Context Menu in Windows Explorer I did a quick and easy edit to the registry.  I have used this registry hack for years in WinXP but found no blog posts on how to do the same in Win 7….until now.

Thanks goes to Ralph Arvesen for his post which pointed me in the right direction.

Before you begin you must change the Windows System date format under Regional Settings in Control Panel.  You cannot use / in the date format since this is an invalid character for folder names.  Change the / to – in the date format.  You cannot skip this step.  Your date format must contain valid characters for folder names.  That’s all the ID-10-T error trapping I can offer.

Below are the steps to add the New (DATE) Folder to Windows Explorer’s Context Menu in Windows 7. 

Use WindowsKey+R to get the Run dialog open and type Regedit

[HKEY_CLASSES_ROOT\Directory\shell\cmd]

Add a new Key

New (DATE) Folder

               (Add another New Key under this key called “command” and you get the following

[HKEY_CLASSES_ROOT\Directory\shell\cmd\New (DATE) Folder\command]

Rclick Modify the Default value for command key and type the following

CMD.EXE /C MD “%1\%%DATE%%”

Try it.  Open Windows Explorer.  Browse to a folder. Right Click and pick New (DATE) Folder.

Those who use Civil 3D without Raster Design can get the Raster Design Object enabler to enable you to insert MrSID and ECW image file formats using the MAPIINSERT command. This command inserts an image as a Raster Object. There is another way to display images in Civil 3D. In Civil 3D 2011 you do not need an object enabler to connect to a MrSID file. This file format is supported by FDO.The main advantage to connecting to an image using FDO is better memory management of images. Use Feature Data Objects (FDO) to “connect” to an image rather than “insert” the image. FDO is a part of Map 3D which is a part of Civil 3D. Type MAPWSPACE on the command line to turn ON the Task Pane. On the Display Manager Tab click on the Data button and choose Connect to Data. Now you have the Data Connect palette open. On the left side highlight Add Raster Image or Surface Connection. On the right side choose one of the buttons above the Connect button (grayed out). The one on the left allows you to connect to a single image file. The one on the right allows you to connect to an entire folder of images. The rest of the process is fairly intuitive so I’ll end it here.
