CONSTRUCTIVE SOLID GEOMETRY CONCEPTSInventor Tutorial D3

LOCATOR This is the object we are going to work on There are always several different ways to create the 3D objects.

Think ahead about the different additions, and cuts you will make.

DO 1 Start a new METRIC part

Click on Metric under templates Then choose Standard(mm).ipt

DO 2 Make the Origin

Components Visable Start a New Sketch on

the XZ Plane We are going to make

the base feature This is the primary

solid feature of the model

Make a two point rectangle, the base should be aligned to the X axis

DO 3 Add the

dimensions You can always go

back and edit dimensions

If you don’t have a tool selected you can move dimensions around

Set the dimensions as shown

USING THE MEASUREMENT TOOL Change to the Inspect tab of the

ribbon Choose Area Click the closed shape, and you

can see the area of that shape We can use loop to find the

perimeter

DO 4 Extrude the Shape 15mm DOWN Look at the bottom of the Shape,

it should look like mine (your yellow work planes might look different)

Create a new 2d Sketch based on the bottom face

DO 5 Draw a circle from the mid point

(your cursor will turn green), to the outside edge of the rectangle

Finish your sketch

DO 6 Go to the home view,

your view should look like mine, if it doesn’t, use the cube to fix it, so that it does match

Extrude it up 40, but don’t click OK yet

SOLID GEOMETRY ACTIONS

Union/Join• Make one new

combined shape

Cut• We remove a

portion of the shape

Intersect• We only keep

the part where the two shapes overlap

DO 7 Finish the extrude Create another 2d Sketch on the

top face of the cylinder

DO 8 Draw a circle based

on the cylinder’s center point

Add a Dimension, and set the diameter to 30mm

Finish the Sketch

DO 9 Extrude the shape down and cut

the circle Set the Extents to ALL Finish the Extrude

DO 10 Now we are going to add a

Placed Feature Instead of creating a new

sketch to add a hole, we are going to use the hole tool

Click Hole Tool

REQUIRED GEOMETRY A linear hole needs

three pieces of geometry Face Reference 1 Reference 2

To set them, click the arrow, then pick the geometry

DO 11 Pick Face, then select the

horizontal top face shown

DO 12 For reference 1, choose the top

edge Set dimension to 25

DO 13 For reference 2, choose the right

edge Set dimension to 30

DO 14 Set the drill size to 20mm and

make sure Termination is set to through all

Click OK

DO 15 Create a new 2D Sketch on the

Right vertical sketch as shown

DO 16 Make a rectangle as shown,

and add the required dimensions

Finish the sketch

DO 17 Extrude the

rectangle Cut towards the

hole Set the Extents to

To Next, that will make it go until it hits something different (like the hole

Finish the Extrusion
