![]() This plane should be pinned and set to “Not a Reference.” Create another reference plane and name it “L R.” Lock “Family_AA” to this reference plane, and make it a weak reference. Set the “L R” default to 4’, to align the plan symbol and the elevation symbol when families are placed. This sets the maximum offset, so adjust if required. ![]() To allow the offset to go both left and right of the center reference plane, add a reference plane to the 4’ left of the center reference plane. Revit will not allow negative values in dimensions, so the base plane can not be placed in the center of the symbol. To control the side-to-side movement of the receptacle symbol, a vertical reference plane must be dimensioned and labeled. To get the proper offset for any scale, add the following formula to the “Offset From Wall2” parameter “Offset From Wall / 1′ * Plan Scale.” The “Plan Scale” parameter must be manually entered by the user. Click on the Family Types button on the ribbon and, as a default, set the “Plan Scale” parameter to 0’-0 1/8”. At this time, Revit families do not have a parameter for the scale of the view in which they are placed. The Plan Scale parameter will be used as a mechanism for the user to convey the view scale to the family. Otherwise, an entered 6” offset may move the receptacle symbol radically more or less than 6” on the plan. This will allow the user to add a dimension to move the receptacle symbology off the wall without moving the model portion of the family.īecause the receptacle family scale is based on the plan scale, and it is unknown what that scale will be until it is placed in a view, a way to push that information to the family is needed. Assign the “Offset From Wall” in your nested family to the “Offset From Wall2” parameter in the host family by selecting “Family_AA” and selecting the box to the right of the “Offset From Wall” parameter in the Properties palette and then selecting the “Offset From Wall2” parameter in the dialog that pops up. Load “Family _AA” into the “Receptacle” family and place it on the intersection of the two main reference planes. Offset From WallĬreate the following type Parameters in the new family. Name the new family “Receptacle.”Ĭreate the following instance Parameters in the new family. In any case, the family will be built the same, but “push/pull” options are slightly different once the family is placed into the model. Wall-based or other options can be used here, so pick what works to maintain company standards. Add a dimension from the reference line to the horizontal reference plane in “Family_AA.” Add an instance parameter to the dimension and name it “Offset From Wall.” This will add the ability to move the plan symbol away from the hosting wall or entity.Ĭreate a third family using the Generic Face Based or the Generic Model template. Using an aligned dimension or the Align tool, lock the nested receptacle family to the reference line. ![]() ![]() Draw a horizontal reference line under the symbology, and make it a weak reference. Place the nested symbology above the horizontal reference plane in Family_AA, but centered on the vertical plane. Name it “Family_AA.” Load “Family_A” into “Family_AA” to create a nested family. Use the generic annotation family template again. Controlling Up and Down MovementĬreate another generic family. Name it “Family_A.” Using detail lines, draw the plan symbol at the size it would be on a plotted sheet. Use the generic annotation family template provided with Revit. Using a receptacle family as an example, this article will demonstrate how to do just that.īegin by creating the symbolic annotation family of the plan symbol. That is, unless the symbolic part of the family can be independently moved from the modeled component. Because it is oversized, however, placing receptacles close together in the model causes the plan symbols to overlap. It has to be larger to effectively convey the receptacle type and still be readable at a 1/8th scale. The symbolic representation for a receptacle, for example is larger than the actual three-dimensional modeled receptacle used for elevations and interference detection. Electrical construction documents depend upon the use of symbolic representations for devices in plan view.
