Revisions are an inevitable part of precast projects. Read here how to create, apply and edit revisions in IMPACT Revit projects. 

Create Revision list

Document the project changes in a revision list. Go to Revit -> View -> Revisions in order to find the Revisions function in Revit. Write down the date, description, and any additional information to the revision, that you want to add.

There are two different ways to add revisions:

  1. Per Project - the whole project will have one list of revisions. This means that a drawing could have e.g. Revision nr 567. 
  2. Per Sheet - the numbering of revisions will start from 1 or A on each sheet.   

Notice that this is list is showing revisions for the whole Revit model.  Later on, the user is able to choose a revision from the list that needs to be applied to the element shop drawing sheet.

Apply Revision

A shop drawing can have more than one sheet. Depending on which alternative you are using, there are different ways to add revisions to those sheets. In the example below, we are pretending that we have one shop drawing with two sheets.  

  1. If you are using revisions ´Per Project´ - If you make a change on sheet 1, you just need to add a revision for that change to sheet 1. Sheet 2 can be empty or have other revisions. 

    Figure 2. Revisions according to alternative 1.

    Figure 3. Result in Project Manager.

  2. If you are using revisions ´Per Sheet´ - If you make a change on sheet 1, you need to add the same revision to sheet 2. Otherwise, the next revision you add to sheet two will have the same revision number or letter. See the pictures below. 

    Figure 4. Different revisions were added to each sheet, but both have the same revision no. This is wrong.

    Figure 5. All revisions for the drawing are added to all sheets. In that way, revision no. is correct. 

    Figure 6. Result in Project Manager.

Once the revision list is created, you are able to apply revisions on the shop drawing sheets. 

Open the shop drawing sheet properties and find Revisions on Sheet. See the picture below.

Choose revisions from the list and press OK. Selected revisions will appear on the sheet and in the drawing head.

Show revisions in Project Manager

In order to show sheet revisions in IMPACT Project Manager, the Shop Drawing and the IMPACT project must be updated.

Follow these two steps: 

  • 1. Update the shop drawing via Update Shop Drawing command in Revit.

Notice, that in version 15.0.018 and higher, the user has a possibility to preserve reinforcement annotations, spot elevations and dimensions.

2. Update the IMPACT project using the Refresh button in Project Manager. The revision name and date will be displayed.

Add revision schedule to a sheet family

When creating a new sheet from scratch, there will not be any revision schedule available as default. The schedule can be added pretty quick. 

1. Make sure that the sheet family is opened. Go to the 'View' tab and find 'Revision Schedule'.
Figure 6. Revision Schedules can be added to a sheet family with the command 'Revision Schedule'.

2. There are a limited no. of parameters that can be used for revision schedules predefined by Autodesk. In current versions, the user cannot add company specific parameters. 


Figure 7. There are six default parameters available for the revisions.

3. When the required parameters are selected and placed in the right area (Schedule fields) shown in Figure 7 it is time to configure the rest of the schedule. In the tab 'Sorting/Grouping' one should decide which parameter that should control the sorting in the list. Usually, it is the 'Revision Number' (1) that is used for this. Set the sorting to 'Ascending' (2) if the list should be sorted in numerical or alphabetical order starting with '1' or 'A'. Use the 'Itemize every instance' (3) to make sure that each revision only get one row in the schedule. 


Figure 8. Select preferred sorting for the revisions.

4. In the formatting, one can change the headlines if required. 


Figure 9. One can change the names of the headers in the 'Formatting' tab.

5. In the last tab 'Appearance', one can decide the preferred look of the schedule. Suggested settings is shown in the picture below. (1) decides if the schedule should grow upwards or downwards. Usually, the revisions are placed on top of the drawing panel, which means that the most common setting will be 'Bottom-up'. (2) makes sure that there will not be any empty field between the headers and the revisions. (3) decides what to show on the drawing. Usually, the title is turned of and the headers will be visible. 


Figure 10. Suggested setup for appearance. 

When the settings are done, finish with 'OK'. 

To control the size of the text, click on 'Font' in the 'Modify Schedule/Quantities' tab and specify preferred size.

The last step is to place the schedule on the sheet.


Figure 12. Place the schedule at the preferred place on the sheet. 

After above steps are done, save the sheet and load into the shop drawing template if required.

Add current revision to the drawing panel

In addition to the revision list, it is often required to highlight the current revision. This is done by adding a parameter to a label. 

1. Make sure that the sheet family is opened. Go to the drawing panel. (NOTE: The drawing panel could sometimes be grouped together. If that is the case, double click on the group to make it editable). Create a label (1) and place it at the preferred location in the panel (2).


Figure 13. Place the label.

2. Select the parameter 'Current Revision' (1) and add it to the label (2). When it is added (3) there are some fields that could be specified. The only relevant field in this case is a sample value (4) which can be set to e.g. A or 1. Finish with 'OK'.


Figure 14. Add the parameter to the label. 

3. The label could be of the wrong size. That can be changed in the properties window. 


Figure 15. Change the size of the label.

After above steps are done, save the sheet and load into the shop drawing template if required.
