Drag and select the desired shape
Move circle away of origin to a desires distance
Modify> rotational repeat
Shape
Change number of circles by changing ‘repetitions’
We can add border outline
Change width from 0.1 to 1.1
Uniform scale
Scale change
Change color of fill and border
Add a parameter
Final Result
Export the design (choose SVG or DXF)

Making edges¶

Component 1 - Edge A¶

Transform origin hold Ctrl and choose origin point.

Set Parameters

Reference

Finger-joint

Leftover 1

Leftover 2

Check (change length to 4.6)

That edges tabs are too long fix parameter numTabs by adding +0.5 to equation

Modifify<’weld’

Component 2 - Edge B¶

Remove Leftover 1 and Leftover 2

Remove reference rectangle Edge A

Remove reference rectangle Edge B

Component 3 - Front Panel Panel (Use all Edge A)¶

Upper

Right

For Down use ‘Mirror’

For Left use ‘Mirror’

Weld

Filling corner

Corner 1

Corner 2

Corner 3

Corner 4

Union aka ‘weld’

Component 4 - Side Panel (Right and left should be Edge B) + remove corners and Edge A and move mirror to Edge B¶

Component 5 - Top panel (Edge B) + in Top and bottom, Remove Edge A, Replace mirror to Edge b¶

Box Layout + Parameters¶

Front layout + parameters

Side layout + parameters

Top layout + parameters

Tip For laser machines setup¶

3d – Program: Tinkercad¶

This is an online website for 3d-design, it have built in tutorial that helps you understand how to use the tools to get desired design.

Chess pawn example¶

I created a chess pawn by following the tutorial provided by Tinkercad

Class Activity - Design solution¶

Scenarios Exercise¶

Wire-managment¶

Wire management device can carry up to 18 wire it can be stick to table due to the fabric material underneath. Made out of plastic which is flexible to ensure that you can the wire in place with ease.

Sun-plant pot¶

Portable flower pot that can be easily hang to curtans.

design principle¶

Today we have discussed the concept of design principles. I noticed three object around me and I commented regarding their design principle Three object and say what design principle apply to them.

Analogous colors: 2 side color (yellow-green)

Repetition: the way of connecting to each other follow the same pattern

Hierarchy: As the structure is being build an elevation happens

Unity: many parts to form structure

Balance: Symmetrical balance

Proportion: The fire design there is two diffrent size that gives depth illusion

Color contrast: Red (Fire) vs Blue (Ice)

Shapes: the main frame consist of 2 similar size circules, 1 smaller circle between them in a triangle shape and connected by lines.

Symetrical Balance: exactly similar halves

Emphasis: The tire-ring colored yellow (pop-uo) while the rest of the parts is black neutral)

Proportion: Circle in diffrent sizes to for ring, tire and screws.

Pattern: the rubber-tire have pattern for stability

Movement: the patter is like an arrow directional which gives illusion of movement.
