If you’re a user of ESTmep and Revit Fabrication parts, consider yourself warned. I’ve recently had some dialog with an industry colleague and the discussion of Cost data in Revit came up.
We know that that a Revit file which uses Fabrication Parts contains a copy of your Fabrication Configuration (Database). We also know that the Fabrication Extension for Revit now allows you to run reports. Those reports can also report on Cost data. That’s generally a good thing in most firms using ESTmep, exposing that Cost data to Revit users can be very helpful.
Now when you send someone your Revit model, they do NOT have access to your database (Unless you send that to them a well). Without your database, the Fabrication Add-In will not find the reports and the option is grayed out.
You also can’t change the configuration either because the drop down is disabled. They need your database to do anything….maybe.
So this sounds like we’re OK but let me assure you that’s not the case. Your database isn’t “available” to the person who had your Revit file but it is contained within the Revit file itself. And even though the Revit API’s don’t give you access to the costing data, it can be extracted.
I won’t go into details for the sake of security in our industry but rest assured, there is a process where as a user can extract your cost data. This includes being able to figure our your vendor pricing multipliers.
What To Do?
That leaves the question about what to do. Some may be familiar with the option in Edit Configuration that disables the storing of EST tables in DWG files. This has NO effect or control of Revit. Sure would be nice if it did nit that’s not the case.
So there’s really 2 options that I can see….
- Remove or Rename the COST.MAP, ETIMES.MAP, FTIMES.MAP and SUPPLIER.MAP tables from your database. These are where labor rates, times and costs are stored. Without these tables,, Revit can not store this information in the model. If you’re previously had a Revit model with this information saved, rename/remove the files and reload your configuration and the data will be removed. The down size is you’ll no longer be able to use ESTmep.
- Make a copy of your database without the COST.MAP, ETIMES.MAP, FTIMES.MAP and SUPPLIER.MAP tables and have Revit point to that. Each time you update your Fabrication database, you’ll need to refresh this copy. It’s fairly easy to script this process and have those files removed. The down side is you’ll no longer have access to Cost data in Revit but at least you can keep using ESTmep internally.
If you feel this is unacceptable, please submit a support ticket with Autodesk. The more people that raise the issue, the more likely that it will be addressed in a future release or update. To date, all they told me is the option I’ve outlined are the ONLY way to address the issue.
