2. Computer Aided design¶
one of the important method to design is digital designing specially that most of the machine use in fabrication require a digital design rather its 2d or 3d such a 3d printer or laser cutter .
2D Designs¶
adobe illustrator (kwala)¶
open a new file and choose the artboard size to work on it choose specific size or stander size
the application work with layers and it need to arranged
start with draw a line with drag and click
change the strok size
to draw the arms use the pin tools and draw a point then drag the other point to draw a curve
u can delet or arang the final drawing by arange the intersection line point
if ther is a angle edge we can make it smooth
by click alt to apeer to you the red point near the corner and drag it
copy the element by click alt and drag it to duplicate
and to reflect it left click on the mouse and chose transform-reflect
choose the axis’s and press OK
use the pin tools to draw the head by click the start point and click the end point and drag
the ears the same
copy and reflect the ear into the other site
add ears details
to draw the nose we need middle line and half nose and then reflect it to have a symmetrical nose
and select all the lines and left click-joint to crate full nose to fill it
and fill it with the fill tool in the prosperity panel on the left above and chose the color
use the shape tool to draw the circle and keep press shift to keep the circle perfect
the line is intersection with the hand to remove it
paint the hand with Wight and and put the layer upper the line
AutoCAD (Mosaic)¶
other design using Autocad
open the Autocad (start drawing)
choose the line tool
the + is the cursor and click and drag to draw the line
draw in line ( vertical , horizontal and diagonal)
draw and pattern using the lines
select the pattern the been drawing
then chose the outline and type the thickness number
and press enter and cose the line you want to outline it and press enter
to remove some of the intersection line
type trim and chose all the lines you want to trim them
the design after cleaning
and to extend line use type extend and chose the line
chose the in the triangle to mirror it type mirror and chose the axis that you want to mirror it from
the result
3d designs¶
SketchUp (Rubik’s cube)¶
use the square and type the dimension
type P to extrude the object and type the Hight number
use the measuring and distance
and divide it horizontally
draw lines over the tabe to divide the face
draw out line to each square by using offset tool
delete the intersection lines that show in the picture to connect the faces together
select each square and press P to extrude it
use the material color and bucket to color the shape
the final result
to downlode the file
[cube design](
blender (hammer)¶
chose general
select the left face and press E and move the face to extrudit
press S to scale it down
press E to extrude twice
Press S to scale up
to make the it some round we need to add geometry to the object using loop cuts
1 press CTRL R and chose the edge you want to cut
and use the scroll wheel to chose how many cuts
add 2 cuts and press click to center them
select the 9 faces on the end
turning the faces into a single face by choosing
to make it round
then press E to extrude
to add a bevel press CTRL B and chose the bevel size
in the other side E to extrude then S to scale the e to extrude 2 time then s to scale it again the E to extrude
then we want to transform this cube section into a sphere shape
to select all the object front and back click the show whole screen transparent
select the cube and transform to sphere
ALT and use and select the loop to flatting it in the Y axis Press S then Y then 0 then enter and move it in my axis by press G then Y
and repet it to some of the faces
to smoothed the object
switch to the modifier panel and add subdivision surfers modifiers
to have a sharper edges we can do this by adding extra geometry
press tap to switch to edit mood
by Press CNTRL R left click and slid it close to the edge and left click again and repeat to every edge you want to sharpen it
to add hole in the middle
