WELCOME TO MY WEEK 2

Computer-aided Design

Hi and Welcome..this is my second week in Fab Academy and things are rolling out very well.

Prof. Neil led the Fab Academy in the Computer-Aided Design class:

The session commenced with students from all the 50 Fab-labs worldwide getting to know and familiarise with each other via video-link.

In Computer-aided Design several modes are available: 2D & 2.5D design which is comprised of Raster(tools include: Scan, Gimp, Krita, Photoshop & MyPaint) and Vector(tools needed: InkSpace,Iodraw,
Scribus,Illustrator,LibreCAD, qCAD etc.)

3D Design is also available and has several types: Constructive Solid Geometry, Hierarchical, Parametric, Procedural boundary(b-rep), Function(f-rep) Representations, GUIs, Scripting, HDLs etc
Several programs are involved when 3D is involved: Tinkercad, fabmodules/fabserver, Blender, FreeCad, Rhino, Solidworks, Grasshopper, Inventor, AutoCAD, MAYA, Alias, NX, Creo, AC3D....etc.

Game engines such as Unity and Unreal are available for various developments and designs.

Simulation is a very key aspect when it comes to any design so as to pre-visualize the final model or design you`re working on: tools include:Elmer, COMSOL, Simulation, ANSYS, Nastran and Abacus etc

Please for all details and descriptive information on these Tools and their application in Computer-aided Design...Check the Session here computer-aided design

Assignment

In week 2, I was required to Model( Draw, Animate, Render, Simulate) My potential final project that I had proposed in Week 1. using as many CAD software tools as possible.

Solution

Before you take a look at my Rhino designs:

Let me say I`ve really had a nice week working with and learning Rhino, I bet I`m now a Rhino dwarf-guru..hahaha..anyway I wanted first of all to show you a few tricks I`ve learnt so far
and implemented while designing my potential final project.

There are many commands available but I guarantee you 80% success with these commands while using Rhino for your 3D designs...Just type In the command box whatever command you want to use..

Ok Let`s do this:

For drawing common shapes use: (you can either click to draw or type the dimensions you want)
-circle
-line
-rec
-polyline
-curve

For scaling/resizing:
-scale1D: good for resizing lines
-scale2D: good for resizing flat shapes
-scale (you can indicate with numbers the scaling factor)

For measurements:
-length: lenght of line or curve
-distance: distance between two points
-area: area of a surface

For translation:
-move: move an object to another location with respect to a specific point in the object
-orient: good when the thing you're moving is asymmetric/sided/chiral
-copy
-offset: scale and copy
-arraycrv: orient and copy

For 2d-3d-2d:
-loft: make connecting surface between two lines/curves
-make2d: create 2d shape of selected surface, according to current view
-unrollSrf: turn a volume into flat components
-dupBorders: produce curve from boundary of a surface

For cutting:
-explode
-split: divides a line/curve/surface at a center point/line/intersective-surf/curv
-trim: split + delete
-extend

For makimg many out of one:
-divide: dividing lines/curves into equal parts
-rebuild: either turn cuves into lines or make ugly curves pretty curves

For housekeeping/getting-around:
-layer: show layers window (use many layers!)
-show/hide
-setPt
-zs: zoom set, show you just the selected object in the active transport
-join: make one curve out of many segements

Hurreh!! and finally this is how I tackled Week 2 assignment using Rhino:

project

Please join me in practising with other design tools:Tinkercad, fabmodules/fabserver, Blender, FreeCad, Solidworks, Grasshopper, Inventor, AutoCAD, MAYA etc.so as to be all-round when
solving Design problems and offering sound Design solutions.
