Complex Column, How would you model this?

Anonymous — Thu, 20 Dec 2018 18:56:54 GMT

Hello everyone,

I've a fairly complex column that needs to be modeled in Revit. The only way I was able to achieve the geometry for this column was in a conceptual massing environment where I used a blend, added profiles, and shaped the curvature of the column capital. This family is attached.

My initial approach was to model in the conceptual mass environment then change the category to a column; however, quickly realized Revit doesn't allow this nor does it allow for the mass family to be loaded into a column family.

Next I exported the geometry of the mass as a DWG or DXF and imported that geometry into a structural column family instead - that worked. However, the nature of the building where the columns attach at the top is a curved profile thus all column heights are different. Creating a separate column for every unique height doesn't seem efficient and once I export the geometry to a CAD format I lose the ability to manipulate it via parameters...

I've attached both families, any suggestions and/or advice would be appreciated.

I would consider to approximate the column shape by using swept blends and then use details to further detail the exact shape

In the screenshot I used 4 swept blends (1 for the column and 3 for the capital). To better approximate the shape you could increas the amount of swpet blends (but would not overdo it for performance reasons).

Two Suggestion.

1)Model the column geometry with adaptive components inside with predefined picking point. once you loaded the adaptive component family u can pick the position depending upon your roof height.

2) try dynamo. if you are familiar with dynamo; by selecting the roof line curve you can crate point on that curve and manipulate that points further to create your column shape.
