Linking Revit Models: Origin to Origin

Revit has an origin point just like AutoCAD.  Revit calls this the "Project Base Point" and by default, it is hidden from us.  It's easy enough to find in a floor plan view by using the "Reveal Hidden Elements" tool. (the little light bulb in the view control bar)

The N/S, E/W, and Elevation coordinates of the project base point are relative to the "Survey Point".  By default these two points are coincident.  This project base point was moved 5 feet left and up for demonstration purposes.

When you link another Revit model into your "host" model, the "Import/Link RVT" dialog box has an option for "Positioning".  The default setting for this option is "Auto - Center to Center".  (I think it's the default simply due to alphabetical sorting.)  If you have ever used the rotate command in Revit with multiple items selected, you will understand how Revit calculates the "Center" of a selection set.  Using …

Ready to ditch Land Desktop? Accelerate Survey Workflows with AutoCAD Civil 3D

Accelerate Survey Workflows with AutoCAD Civil 3DWhen: Thursday, February 23, 2012
Time: 10:00 a.m. Pacific TimeThe techniques for survey are easy to implement, and survey data can be seamlessly transferred from field data applications into virtual design and construction models for display, reduction, management, and design. In this presentation, civil engineering and survey professionals will learn how they can quickly and easily implement the survey specific functionality within the Autodesk infrastructure design solutions.Learn how to accelerate your survey workflows to increase productivity and profitability. The webcast will cover:•Site Investigation•Leveraging GIS Resources•Data Collection•Importing into AutoCAD Civil 3D•Survey Tools•Annotation•Collaborating with Others

Navisworks: Exporting Animation with Scripts

So, you’ve gone to all the work to create an animation with scripts showing motion on individual objects.  Now you‘re ready to export that animation to an external file that will be viewable by individuals who don’t have Navisworks.  
Unfortunately Navisworks does not currently allow this.  
The alternative for this is to create a simulation within “TimeLiner” that shows the objects moving as desired.  The guys over at the “Beyond Design” blog also have written a post  that explains linking animations to timeliner tasks.

Revit: Applying View Templates From Existing Views

You may already know about the ability to modify view settings and V/G Overrides in Revit with “View Templates”.  (It’s common to see these pre-defined in the Project Template.)  But did you know that you don’t even need to create a view template to transfer these settings from one view to another? It’s true!  Here’s how:
In the “Project Browser” find the view that you would like to apply the changes to and “Right-Click” on that view to activate the menu.  From the right-click menu, choose the “Apply View Template” tool.
This will open the “Apply View Template” dialog box.  By default, this dialog box will list all of the view templates that you have defined in the project.  However, (and this is where the magic happens) if you want to select an existing view without creating a view template at all, just check this inconspicuous little box that says “Show Views”.

Now you can select from any view in your project.  Select the view you want to copy your changes from and “Include” or “Exclud…

Revit Architecture: Level Generator

Autodesk Labs have some pretty amazing products to help us do our jobs.  They even offer a free plug-in every month from the Autodesk Developer Network (ADN).  From their website we read: 

"The plugins provided are free* and simple productivity enhancing tools that streamline the use of our design applications. The plugins are developed by Autodesk or by other ADN members. All of the plugins we provide come with full source code to show what goes on inside and will have taken a relatively small amount of time to develop (from half a day up to about a week). The idea behind this is that nothing we deliver will be especially "out-of-reach" for someone wishing to invest in learning and using our Application Program Interfaces (APIs). Hopefully you are inspired to create your own plugins."
The February Plug-in is a level generator for Revit Architecture 2011 and 2012.  It generates multiple adjacent levels with one command. Try it and let us know what you think.

Converting Survey Points to a Shapefile (SHP)

A lot of time you will have the need to convert your survey points in Shapefiles to share with other departments or outside users. There is actually a very quick way of doing that inside Civil 3D!! Here are the steps:
First, insert your survey points into Civil 3D (one of the 5 ways of doing it!!)

Second, go to the OUTPUT tab on your ribbon, go to the EXPORT panel and select "Export Civil Objects to SDF". The "Export to SDF" dialog box will appear, make sure everything here is correct and the location you choose to save it to is correct. Select OK.

Start a new drawing.
Type "MAPIMPORT" into your command line. This will bring up the Import dialog box, make sure your file type is set to Autodesk SDF. Browse to your SDF file you just created and double click it. The MAP Import dialog box appears, deselect any objects you do not want exported out (i.e. everything except Points). Select OK. Your Points should now be imported as SDF object.
Just one more …
