Component Elevation Changes with Wall Base Offset

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 Properties palette when the wall is highlighted.

Align Revit Elevations with Angled Walls

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.

Instance Length Parameter with Grips

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.

Controlling Revit Wall Component Linework

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.

AutoCAD Architecture External Reference Tips

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.

Inexpensive Architectural Design Software

Architectural design software is renowned for being expensive for the major products that are on the market, especially the packages considered as Building Information Modeling (BIM) software. Many designers are looking for something less expensive. That may be due to limited financial resources to spend on software, or to the lack of a need for something more expensive and powerful. This article is devoted to mentioning some architectural design software packages available for less than $2500.

Roombook Extension for Revit 2012 Available

In January 2011, I wrote an article about Autodesk releasing the Roombook Extension for Revit Architecture 2011.  Autodesk has now released the Roombook Extension for Revit Architecture 2012.

According to Autodesk, “The Roombook Extension for Autodesk® Revit® Architecture 2012 software helps calculate the surface area of walls, floors and ceiling elements, room circumferences and the total number of furnishing elements within a project.”  It appears to be unchanged from the version available for Revit Architecture 2011.

The Roombook Extension can be downloaded from the Autodesk Subscription website for subscription members.
