Revit 2D Details Part 4 - Linking 2D and 3D

This is my fourth and last post on 2D details, well at least for now.

If you used the drafting view in the first post on 2D details, the 2D detail is standalone and not connected with any part of the model. This scenario is ideal for details like typical partition details and door details.

If you are used a Callout View, you will have overlaid your detail on the 3D model. What if the underlying elements of the 3D model move? The detail will look a little messed up and uncoordinated. This can be ok as it will be a prompt to make some necessary changes to deal with the changes to the underlying model but can be a little frustrating if the changes are relatively minor and things don't line up.

The original detail.

The RC wall in the mode is moved but the 2D elements remain at the same location.

To ensure the plaster and the partition always align with the RC wall, do the following:

1. Add all the elements to a Group which I introduced in the second post. Once you select a number of 2D elements, you will see the Create Group under Create on the Modify | Lines panel. If you miss any elements, simply select the Group and select Edit Group whereby you will have an option to add or remove elements.

2. Select the Align tool from the Modify panel. Underneath the ribbon you will see some options. The Prefer option allows you to set the preference for which part of the wall can be selected. Select Wall faces as we want to align the face of the RC wall with the back of the plaster.

3. Select the a face of the RC wall first as we want to align to this.
4. Select the back face of the plaster.
5. You will now see a padlock which is open. Click on the padlock to lock it.

6. Do the same again for the left hand side of the RC wall.

Now the back face of the plaster is aligned on 2 sides with the RC wall. You can test this by moving the RC wall. The example above can be downloaded here.
