Users, Choosers, and PDM-less Losers

It’s a fairly common topic on most of the SW fora: “How do I move/manage/protect my files?”.  I suppose someone needs to say it, just as a formality; it doesn’t take very long before someone replies, “You should get a PDM system!”

 Can I get a “Well, Duh!” from the congregation? [Amen, Hallelujah].

The fact is, the vast majority of the SW community are users, not choosers.  They work away in the arena provided by their employer: slow network, weak workstation, outdated software, leaky ceiling and bad coffee.  Users may have loud voices, but usually very little say in what they get to use.  They almost certainly don’t get to decide whether to install and use a PDM system, making the first salvo of well-meaning advice hollow. For whatever reason, management will not allow PDM implementation.

File Management Survival Skills

As CAD skills go, file management tends to get short shrift.  New users-in-training are preoccupied with more pressing issues like changing colors and constraining sketches.  They are in a hurry to get useful so that Sir Boss doesn’t second-guess his hiring decisions.  Especially true for small-to-medium sized businesses, where cost of CAD comes out of Sir Boss’ pocket.

At work, it gets worse.  Projects and priorities appear and change daily.  Many projects get idled or abandoned, and the SW files get scattered across a half-dozen network drives and “My Documents” folders.  Multiple files exist of some parts, leaving no one certain what truly belongs.  Parts get accidentally changed by ham-fisted noobs or over-eager bosses.  In many places, there is no formal ECN process or designated storage area for released files.

Get the picture?  I’ve seen it four times over in the last two years while doing contract work.

Case Study: A Client Awakens

There is hope for some.  My current assignment is at a metal fabrication place with three SW users, plus myself.  The engineering manager saw the mounting file management crisis and tasked me to address it.  PDM was out of the question, as there was no money or support from parent company.  We had to find another way.

The result was a system of protected folders acting as a vault for CAD files and a library for other documents.  The folders are protected using windows security and are owned by a “phantom” user, so that no individual can inadvertently change files under his own login.  So far, it works.  Not as good as PDM, but OK.

What was encouraging was that the manager saw the value of his CAD data.  CAD data is valuable information.  Design data does not come cheap.  Software, hardware, users, training, etc. are all pricey.  Even more costly are the mistakes that can result from mishandled or lost data.  Design data needs careful guardianship.

File Management Survival Skills

File management is a skill set that is no less important than sketching.  There are things every user should know how to do (or at least know can be done).  If you can not do any of these things, you should not be satisfied with your file management skills:

  • Move files to a new folder
  • Create copies of files for work or backup
  • Copy entire assemblies
  • Replace components in an assembly
  • Reconnect “lost” components to an assembly
  • What is a file’s “internal ID” and why it is important
  • Understand how SW finds components and references
  • Use your operating system to protect files and folders

Not a complete list, but enough to get one thinking.

Workaround to edit Macros that are locked on network drive

Question:  I have macros on a network drive and need to edit them.  Unfortunately, someone has them locked (open).  How do I unlock them without going to that computer to manually unload the macros?

Answer: There is a live workaround.  While you cannot edit the files while locked, you can change their folder name! This allows for a sneaky little trick that doesn’t require going to the offending computer.

Simply rename the folder on the network drive where the macros are located. Then copy that folder (files and all) to the same drive. Rename the new folder to be the same name as before the original folder was renamed.

The macros in the old folder with the changed name will still be locked out, but the macros in the new folder with the original name will be free to edit!

In a day or so, the files in the old folder will be unlocked again.  Simply delete the old folder at that time.

Addendum: It should be noted that this method will not always work.  However, it is worth a try before taking any other action.
