Hello RevitCity Forum.
I am looking for assistance in defining the parameters required to create a filter to identify and color code wall elements that have specific top of wall spot elevations in plan view.
For example, the attached concrete grade beam section is constructed with an 18” wide tall wall element (below) and a 10” wide X 0’-4” tall wall element (curb) joined on top. The plan view illustrates the curb (green) and the balance of the grade beam (below) in purple.
The intent is to create a plan view that will use a filter to identify and color code the wall elements that are at elevation 5’-2” (similar to the attached color coded plan view). Please note that there are several grade beam configurations therefore the wall thicknesses that may be at elevation 5’-2” can be of any thickness and height.
The colors on the plan view have been applied via graphic overrides based on manually selecting the walls that have a top elevation = 5’-2”. This method works, but has the obvious issue as it is a static analysis and relies on manual-visual identification. If the walls change in elevation then the surface pattern identifications will not change unless manually modified.
What is the process to create a filter that will programmatically identify only the wall elements (of any thickness) that have a specific given top elevation (5’-2” for this example)?
Also, it seems the parameter formula “Height” = “Area” / “Length” is not 100% accurate; especially for walls that do not have constant cross-section as illustrated in the elevation view.
Searching this and other forums has not yet provided the specific answer and my apologies if there is a solution posted to this or a similar question. Thanks in advance.
