As many of you have seen, read or experienced, Revit MEP 2011 includes some great new features and improvements. We'll be hitting on as many of these as possible during the next few weeks/months. Of all disciplines, I'm sure the Electrical folks are among the happiest with the new conduit/cable tray functionality, as well as the new and improved panel schedule workflow.
Included in the electrical improvements are the creation/customization of Demand Factors and Load Classifications. If you'd like to read a little more about this feature, feel free to check out this post.
Meanwhile, I wanted to cover a known limitation with respect to the Load Sub-Classification Motor parameter. There will also be a technical solution posted on Autodesk.com. If you are an Electrical designer, please read on....
The Load Sub-Classification Motor parameter will need to be mapped as a family parameter in the Parameter Properties dialog. This includes out-of-the-box content as well as user-created content. To update electrical families so that the parameter works as expected:
- Select a family to update in the project.
- On the ribbon, click the Edit Family button.
- Select the electrical connector.
- In the Properties palette, click the button to the right of the value for Load Sub-Classification Motor.
5. In the Associate Family Parameter dialog, click Add Parameter.
6. In the Parameter Properties dialog, verify that the Family parameter option is enabled.
7. Name the parameter (i.e. Motor). This name will appear in the Properties or Type Properties of the family when editing it in a project.
8. Select either Type or Instance to define whether the parameter is an Instance or Type parameter.
9. For Group parameter under, select the section where the parameter should appear. Click OK twice.
10. On the ribbon, click the Load into Project button.
The Load Sub-Classification Motor parameter is now mapped to the family, so it may be changed in the project. This edit should be done to the family file that is loaded into projects so it will only need to be performed once.
Hope this information is helpful.
