091001 STL Model for Skyscraper 03

The STL model for Skyscraper 03 is out! Thank god. Here are couple of shots of the printing process and end physical product.


3d-printing in process


3d-printing 50%


It is good that I rotated the model and laid it flat so the printing time is shorter

090930 Skyscraper 03

I have been working on Skyscraper 03 for more than 12 hours and finally I've got the scripts working, STL ready, and renderable. Pretty happy about the result to be honest. And hopefully the 3d-print will work perfectly fine for my 1:1000 model.

I will go through the process from here on.


Imported the mapped-points-drawings into AutoCAD which the acquirement of points have been illustrated in the previous post.


Started mapping up the highlighted points using dots and crosslines.


Here's the results for the 4 categories


I decided to use square panel for the dots. The facades of the tower are also laid out with 10m x 10m square grids


Array across the panels with the 4 block panels. Rotate them to give more variations on the facades


It seems that 10m x 10m will contain a lot of points. So I made the grid to 20m x 20m and the density of points is just about right


Import the dwg/dxf file into Rhino


Applied Voronoi-2D script on facade and started to create some floor plates.


The wireframe generated by Voronoi-2D is then imported to 3ds max for piping (i.e. making from lines/curves to solid/mesh)


Isolated the wireframe to reduce memory usage for Scripts


I have modifed the script that I wrote in the previous post. This script is more simple. What it does is considering
-> each cell as individual
-> offset curve inward
-> CurvethroughPolyline
-> clean up the scene
This script can be made much better in terms of the return and the input variables.


Then I did a simple PlanarSrf command by selecting all curves in the scene to create the cutout surfaces


I wrote another script for this particular move - Extrude each surface to its normal.
Each surface has their own normal of extrude. If you type in ExtrudeSrf and select all the surfaces, you might encounter a problem where some surfaces might extrude along the construction plane which is undesirable. So this script does:
-> enter extrude height value (preset Cap and Both sides prior to runscript)
-> considering each surface
-> extrude individually via its normal
-> clean up the scene
It runs quite a while and this is the result with a thickness for the "membrane"


This image shows the combination of the primary cell structure + the membranes


Playing with the shapes of the floor plates


And stack them up with a rotating configuration. The idea here is to create some double volume spaces.


Here is the overall model!


Import the whole model into 3dsmax for basic renderings


Rendering in process... and below are the resulting renders.









I like this render the most.

090824 3D Print for Skyscraper 01

There was an error on layer 354 (out of 588) when the printing is processing.
But it turned out to be a pretty decent sectional model even though there are still hundreds layers to go.

090822 Skyscraper 01 STL Preparation

Spent quite a bit of time in "CheckMesh" and making sure that the STL file is workable for 3D print.

The Tower #01 is marked at a dimension of (~45-60)L x (~45-60)W x (~100)H
The total volume is marked at 74509.6951 cubic mm = 4.54686 cubic inch.
I assume the price tag for Tower #01 is at AUD45 since AUD10 = 1 cubic inch.

090822 Skyscraper 01

Today I made a tower model based on the pattern of square frame and sine curve.

The tower's mesh surface is offset according to a sine curve and the mesh panel is made of rhombus component.

Here's the result:





Hopefully I can make a 3d print at the size of ~150mm x 100mm by Wednesday.

090728 Vase Transformer

We have to design a vase for our 1st tutorial exercise. This vase is going to be 3d printed or laser cut on Wednesday 090729. I think my vase is going to be 3d printed. Basically, the vase has a simple design which is lofted with basic geometry.



Step 1
- Draw 2 ellipses, 1 circle, 1 triangle within 50mm x 50mm grid extend



Step 2
- Offset each shapes by 1mm



Step 3
- Select all inner shapes and loft them



Step 4
- Select all outer shapes and loft them



Step 5
- BlendSrf the top of the vase with default blend mode



Step 6
- Draw a CutPlane prepare to create the capacity for the vase
- Trim the inner lofted surface
- Create surfaces for the base by using PlanarSrf



Step 7
- Draw a base plane with PlanarSrf



Step 8
- Apply timber material to the vase
- Apply light grey diffuse colour to the base plane
- Render the vase with V-ray with caustics On
