Create Site Building that could be editable

[munchel_kim5SSTC]

Hi all,

Currently working with GIS-related revit api development.

Reading SHP data of building in points, creating boundary line based with points and creating masses with commands(part of code)

Solid geobldg = GeometryCreationUtilities.CreateExtrusionGeometry(new CurveLoop[] { profileloop }, XYZ.BasisZ, bldgHeight[i], opt);

During development, I had issues that some of the GIS-based data are old, and in those cases, the designer wanted to manually fix them. 

(eg. recreate, erase, or modify partial details, etc)

Is is possible to create masses in revit api that could be editable after creation?

Thank you for a very valid question. Unfortunately, in this specific context, the answer is rather tending towards no.

You  seem to be creating a family definition to represent the mass. That is a viable way to go. The family definition could theoretically be created to be parametrically driven, in which case the user would be able to modify parameter values later in the project file to adapt the mass instance geometry. 

Another way to create mass representations would be to use DirectShape elements:

That would avoid the complexity of defining a family definition and placing an instance.

However, direct shapes are not easily editable, either, cf.:
