Revit Tutorial: Making the Switch — AutoCAD to Revit, Part 2

Building design firms transitioning to Autodesk Revit should plan for setup and troubleshooting before anything goes wrong.

Some content cannot be made in advance because it is unique to a project. Items such as this reception desk need to be created concurrent to the project development.

This article is the second in a two-part series about transitioning to Autodesk Revit, but many of the principles described here could apply to any BIM (building information modeling) software transition. This series is intended for those who have not ventured down the BIM road yet, or who have the software but don't know what to do next.

The first part addressed the reasons to switch, the timing, and who to train within the firm; this part will explain which content and template setup you'll need, and what to do when things go wrong.

Content and Template Setup

Another aspect of training and implementation is content and template setup. It is not wise to begin a project without having begun this task; however, you don't want to spend too much time trying to get everything perfect prior to the first pilot project.

Template essentials include:

  • Titleblock with company logo (matching the CAD version
  • Text and dimension styles
  • Schedules (door, room finish, light fixture, VAV, AHU, etc.)
  • Floor plan views and levels
    • For a four-story building you would have:
      • Four levels
      • Four floor plan views
      • Four ceiling plan views
  • Sheets (some are empty; others are not)
    • Title sheet with sheet index, standard notes, and graphics
    • Plans, elevations, sections, details sheets (these are mostly empty place-holder sheets)
    • Schedules
      • Empty schedules can be placed on sheets; they fill themselves out as the model is developed
      • Some schedules are only for the design team and never go on a sheet
  • Some content
    • Only load the essentials into your template; too much can make your starting template way too big and cluttered
    • Some items, such as walls, cannot exist outside of a project file. In this case, you can set up project files that have one instance of each wall type created in each. When a new wall type is needed, the "wall type" project is opened and the desired wall is copied and pasted into the current project.

CAD Clinic Civil 3D Tutorial:
AutoCAD Civil 3D and Pay Items, Part 2

Learn the ins and outs of the formula file, the last of the three files that create a master pay items list.

By Phillip Zimmerman

In my previous article, I reviewed the pay item definition process and the files necessary to implement a master pay item list. In this month's continuation, I will review the formula file and its purpose.

The formula file's use depends on the units set for a pay item. For example, a corridor's Pave1 area is in square feet, but in the pay item file the units are square yards. A pay item report for Pave1 will be in the pay item area units, not the corridor's square feet. If Pave1's assigned pay item unit type is a weight unit type, the pay item report is Pave1's actual area — or, in this case, Pave1's square feet. In either case, you need a formula to calculate a volume.

Pay Item Units

When creating a corridor, the pavement unit type is square feet. As mentioned above, if a pavement material's pay item's unit is square yards, the report will be in square yards. When producing a pay item report, the report's pavement units are in the pay item's units, not the corridor's actual area units. If Pave1's pay item unit is a weight type, the pay item report will be the corridor's actual units, or square feet. Read more »
