:: Don't Get Lost in CAD-to-BIM Translation

Get everyone on the same page by mapping out the inputs and outputs for your next project — in very specific terms.

In the last edition of the CAD Manager's Newsletter, I opined that translating CAD geometry between BIM (building information modeling) and traditional CAD systems would become an increasingly common challenge for CAD managers. I've heard from a number of readers that they're struggling with this task, and would like some advice on how to deal with it.

In this edition of the newsletter, I'll give you an approach to translating that will work regardless of which CAD formats you use in-house or interact with outside your company. Along the way, I'll point out some action items for you and your company's project manager. Here goes.

Clarify Project Requirements — in Writing

Let's say that you're embarking on a new project that will require you to submit BIM information. Questions abound: What BIM software package will that be — and which version? Will you be required to create floor plans in separate 2D files? Will you need to provide files to government agencies in other formats? Will you need to archive plots using PDF or other raster formats? These are the questions that need to be answered and nailed down with specifics now, so nobody is surprised later.

And as you think about which file formats you'll need to supply, don't forget that over the duration of a multiyear project your software tools may have one or more major updates. This possibility makes it all the more important that clients specify the version of any file formats required. So do not accept, for example, that you'll deliver 2D files in AutoCAD format — instead, specify that you'll supply AutoCAD Architectural 2010 DWG-formatted files.

Finally, I can't stress enough that if it isn't written down, it doesn't count. At the end of the project you'll be required to provide digital information to your client based on the written requirements in the contract. If the contract simply says "Supply all information in BIM," then what "BIM" means is totally open to interpretation. My experience has shown that open interpretations lead to misunderstandings, hard feelings, and lawsuits — and nobody wants those. Read more »


:: CAD Manager's Toolbox: Disk Mirroring for Free

RoboCopy is a powerful, fast way to move files between offices.

Many CAD managers have to support multiple offices, and thus have to move and synchronize large numbers of files between servers. To make this task easier, consider using the powerful, free RoboCopy utility.

This Command line function was created as a server resource kit for XP (XP download available from Microsoft), then made into a native command in the Vista and Windows 7 operating systems. The flexibility of this utility allows for very simple — and fast — disk mirroring between mapped or UNC drives.

As an example, let's say you have a drive folder called Z:\Blocks for all your users in the Houston office. You'd like to share this with your users in the Helsinki office that use the Q:\ drive, and you'd like to make sure that all blocks edited in the Houston office are updated to the Q:\Blocks folder in Helsinki.
