Converting Sketch Models into BIM Models

There seems to be a clash between design sketch models (typically coming from SketchUp or Rhino, but even if they are created with ARCHICAD) and models created for proper BIM use when we need to convert one to the other since they are built with completely different approaches by people with different mindsets.

In a sketch/design model you just want to freely place elements and play with the forms in 3D. In a BIM model however everything should be structured and well-organized. For example in sketching there is no such thing as Home Story, but in ARCHICAD everything has a host. The problem is that a designer would be placing elements in 3D where the design makes it fit and would not want to think about Home Stories and such at the time which can cause some headaches later.

Polygon Reduction in ARCHICAD

If your model is feeling laggy or sluggish, especially in 3D, it may be due to a high number of polygons in the model and on-screen. For example, when navigating in 3D, there is a drop of frames (image stutters).
This article can help you to identify, prevent and reduce polygons in your model, and have a leaner and more efficient model to work with.

Ramp Parapet with Morph Tool

Place a Ramp Object

I felt it is good to share some software specific tips and tricks in between my posts focusing on interoperability. In this post I am sharing a tip on how to create guard walls (parapets) along the edge of a curved ramp using Morph Tool and Solid Element Operation.

Place a ramp object with the settings as shown in the below image and switch to 3D window (press F5).
