I’m a student studying Architecture and have had the opportunity to do work experience at MEMKO. Through my time at MEMKO I learnt CATIA for the first time.  I am writing a blog about what I have learnt including practical applications in a construction environment.

Engineering Templates

In my last post I spoke about User Defined Features (UDF) and how they compare to Power Copies. I explained what a UDF is and how I would use UDFs in a particular scenario. This time I will be talking about Engineering Templates, what they are and how they would be used in a design.

What is an Engineering Template?

It enables the user to describe how to duplicate a component (Products, Parts, etc.) in a more efficient and organised way. Engineering Templates re-use preexisting components and embeds them together, to be used in a new variation of the original design. An Engineering Template is very similar to a User Defined Features and a Power Copy but operate in a much larger scale.

I would use an Engineering Template when modelling a structural member/beam so that it has the ability via parameters to manipulate itself in any given building environment. I would have in both the member/beam model and building environment a set of inputs that would allow the member/beam to be easily instantiated. The inputs would be as simple as a Centre Line and an Orientation Axis, this would ensure the member/beam would be instantiated through the middle of the building environment’s skeleton placement lines.

In my next post I will be discussing Parameters and Formulas; they’re used to easily manipulate a model with a click of a button, to prevent the remodelling of a design. In the near future I will also explain how an Engineering Template can be inserted and used inside an Element Assembly Type along with a User Defined Feature.

User Defined Feature

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.

Power Copy

Welcome to my Blog. For my first post I am discussing Power Copies

What is a Power Copy?

A Power Copy consists of a body, 3D shape reference, which, may have various features that are able to be implemented into a new location. Inputs and parameters are controlled through referenced elements – these consist of: Features, Inputs, Variables, Parameters, etc. In reference to the video below the Screw’s input is the Orientation Axis that is created in both the centre of the Screw and the instantiation Environment (box). Power Copies can be easily modified through either the exposed parameters, or the geometry itself. In the videos below you will see how to create a Power Copy and how to instantiate it into another model:

I would use a Power Copy when there is a need to rapidly generate and automate a repetitive process that have the same input conditions. For example, if I were wanting to generate a pattern that would allow me to have a base location for a roof or wall structure I would ensure that both the Power Copy and building’s environment inputs have specific start and end points, a base line running from the start and end point; and an orientation axis. This would then allow me to generate a set of roof/wall structural systems all at once due to the Power Copy foundation that was done prior.

In my next blog I will be writing about User Defined Feature’s which are quite similar to a Power Copy but are used for different scenarios.
