Overview

In completing this exercise you will

• create new design:
  • create sketches on base and lateral planes
  • draw
    • splines
    • lines
  • constrain a line to a fixed position
  • mirror lines and spline to form a symmetrical profile
  • trim lines
  • create thin extrusion
  • create an extrusion to remove material
  • round the edges of surfaces
• create an album

Creating the design

This example is constructed in three main steps:

• create the basic side profile of the spoon
• remove unnecessary material to leave the spoon profile
• round edges

Side Profile

• add a new sketch to the lateral plane - name the sketch profile
• view onto the new plane (press Shift + w)
• draw the profile of the side of the spoon
  • select the spline tool
  • commence at coordinate 0,0
  • draw points to the right until approximately is reached

Create initial profile

• from the feature menu select extrude profile or click the icon
• make the following settings
  • thin
  • thickness 6mm
  • add material
  • below work plane
  • distance 100mm

Extrude basic profile

Top Profile

This operation consists of four main steps

• select the initial sketch on the base workplane
• create a half profile of the spoon
• mirror the shape
• extrude the shape to remove excess material

• Select the initial sketch on the base workplane

Create half profile

• select the line tool
• commence the vertical axis at (-50, -20) - hold SHIFT key for vertical line
• stop the vertical axis at approximately (-50, 320)
• select the line then
  • constraints menu - toggle fixed (stops line moving)

   

• select the spline tool
• commence on the axis
• draw the half profile
• end on the axis

• from the ends of the axis draw two horizontal lines
• draw one vertical line to overlap the two horizontal lines
• select the trim tool
• trim all overhanging ends of the three new lines

Mirror the half profile lines

• from the line menu select mirror

• click on the Axes tab in the dialog box
  • click on the vertical axis

   

• click on the Lines tab
  • hold down the SHIFT key and click on
    • the spline
    • the horizontal line at the top
    • the vertical line
    • the bottom horizontal line

     

• click the OK button to complete the mirror process

• delete the vertical axis line to produce a valid profile

• from the features menu select extrude or click

• make the following settings on the extrude dialog box
  • sketch to use as profile is initial
  • Subtract material
  • Symmetrical about workplane
  • distance 50m
• Click the OK button to complete the extrusion

Draw axis

Draw spline

Draw half profile

Select axis for mirror

Mirror lines

Remove axis to create valid profile

Extrude to produce spoon profile

Rounding Edges

• select the surface of the spoon using the Select Face tool
• from the features menu select round edges or click the tool from the features toolbar
• set the radius to 1.5mm
• click OK button

Save design as SaladSpoon

Round edges

Album

• create a new album
• Image menu - new image - select SaladSpoon design
• Tools menu - materials browser
• open non- metals
• click the icon then drag to the spoon
• click the update button
• click on the spoon to select it
• from the Image menu select set material properties
• click Set Colour
• make a colour selection
• click the update button
• From the File menu select save then save as SaladSpoon

Investigate

• Image menu - image properties

Change material properties

Extension

• file menu - save copy as - name copy Fork
• open the Fork design
• create a profile to remove material to produce a salad fork
