User Defined Features

In my last post I spoke about Power Copies and how to create one and what type of scenario I would implement it. This week I will be talking about User Defined Features (UDF) and how I would use them in a particular use case.

What is a User Defined Feature?

A User Defined Feature template contains features that are instantiated in a new location. It allows you to extract the required information from a model that enables the rapid evaluation of the overall design. A UDF consists mainly of geometry that are based off individual inputs, and parameters, etc. These inputs enable the UDF to be reused and adaptable in any new environment.

I would use a UDF in a scenario where I would be creating a library of different variations of a particular model, for example, a wall or roof structure. I would then create a UDF for each of the different variations that would allow me to populate them throughout my Building’s Environment. The inputs I would use would be the exterior surface of walls or roof, the start and end points and an orientation axis. Having this operation where I can easily and efficiently choose where  the wall/roof structure goes allows for a quicker assembling of a building’s structure.

In my next blog I will be writing about Engineering Templates, and in the near future I will explain how to instantiate a User Defined Feature via an Element Assembly Type.
