Placing crown molding at the top of cabinetry is very common in residential design and can be easy to do in Revit. Ideally, I would like to use a sweep with a crown molding profile, but Revit utilizes sweeps only for walls when not in the family editor. The trick to making this an easy process for the user is to create a specialty wall that has the desired sweep profile built into it. This allows you draw the “wall” to follow the front edge of the cabinetry at the desired elevation for the crown molding.
The following image shows the resultant crown molding.
It is common to have openings in walls that are not of a consistent width all the way through the wall. An example of this is when a door is recessed into a brick wall and the brick opening is wider than the stud/masonry wall opening or the door. The following illustration shows a door opening in a stud and brick wall with the brick opening wider to allow brickmould casing around the door.
Revit doors and windows, by default, have an opening that goes straight through the wall with a completely rectangular opening. If you just use the default Door.rft or Window.rft with the default opening to create your doors and window families, you will not see the above jogged offset opening.
The secret to getting the walls to cut as you desire is to NOT use the Opening Cut that is in the family template, but use Voids instead.
When placing components on the face of a wall in Revit, the same component may move differently when the wall base offset changes. This can cause frustration to the user by not understanding why it is happening. No one wants to see their component change elevation when they don’t expect it.
Walls can have the bottom offset either up (positive dimension) or down (negative dimension) to raise or lower the base of the wall. While the majority of the time the wall will be at the floor level, there are many times when the wall needs to be above the floor. A couple of examples are a wall that sets on a concrete curb, or a wall which serves as a soffit. The Base Offset parameter for the wall is modified in the Propertiespalette when the wall is highlighted. Continue reading →
When designing buildings, we all know that we often get walls that are non-orthogonal and at various angles to the sheet. With those walls, we often want to get an elevation that is parallel to a particular wall. It is actually easy to do.
I was recently asked about instance parameter grips for a Revit family that was placed in a Revit project file. The family had an instance parameter in it for a dimension and the user was expecting to see grip arrows so that they could manually adjust the size by dragging the grips. The arrow grips did not exist and the user was curious why that was the case.
The answer to the user’s question is actually very simple. When creating a dimension that will be referencing an instance parameter, it is important to dimension between two Reference Planes for the grip arrows to appear.
Architectural drawings have been created throughout the years with the intent of accurately and effectively conveying the design intent to the builder for proper construction of the building. Utilization of CAD made it easier for the designer to show the various components that made up the wall by showing lines representing the edges of each of the wall components. When showing the multiple components of a wall, we have traditionally shown the lines representing the two faces of a wall as darker lines than the interior linework of the wall. When using Revit, this same appearance can be easily accomplished.
External References (xrefs) are an important part of working with AutoCAD and its vertical packages. I consider xrefs a critical and key feature of AutoCAD in the AEC industry and encourage you to look into them if you are not currently utilizing them on your projects. There are many aspects of good utilization of xrefs, but I thought I would list a few tips in this article.
