What is BIM ?

I felt like writing down some fundamental concept of BIM for readers who may not be too familiar with it.


Building Information Modelling or Building Information Management (BIM) is a model-based process of creating and managing building information. It applies from planning stage to design, construction and operational stages of building projects. At the core of the BIM lies the 3D model of the building which is a virtual representation of completed project. This 3D m[……]

Twirling ISO curves


I recently made a quick script commonly used in 3D printed jewerly design for fun.

The function below will take a surface and parameters to get iso curves out of it.

To get the result you want, the input surface will have to be carefully modeled with consideration of direction of U and V on the surface.

As you can see in the script below, output curves will not exactly follow input surfaces as those are only approximated by creating curves from points on the surface.

Interference of sine waves on a plane


This mesh model can be easily modeled with 3DS wave modifier.
Here’s a sample code to achieve the same result with Rhino SDK.
The sample is taking three points of origin of sine waves.

    Dim shit As New Mesh
    Dim gridptsflat As New list (Of point3d)
    Dim gridpts2D As New list (Of list (Of point3d))

    Dim intervalx As Double = x / numx
    Dim intervaly As Double = y / numy


    For i As Integer = 0 To numx[......]

In the age of digital design, designers are destined to face the process of rationalizing the form after a lengthy foreplay of form making in order to fabricate it into an actual product. Ironically, some designers/architects these days fully exploit the capability of freeform design to irrational extreme and put another effort and cost in rationalizing the form therewith. Many of these rationalization processes deal with panelizing the freeform surface such as approximating designed surfa[……]

All the stiffness of modeling environment and constraints in BIM modeling process sometimes give you frustration and less freedom in modeling but in the end it actually results more accurate, parametric (and therefore flexible) model. So the issue should be when to implement BIM after concept design stage.
