ADVANCED 3D TOOLS

ADVANCED TOOLS

• Sweep – Moving a cross-section through a path two form a three-dimensional object• Needs a Cross-section (a sketch) & Trajectory (line to

follow)

• Loft – A Blend of multiple profiles on various planes, they do not need to be paralel planes• Needs multiple sketchs

• Shell – The hollowing out of the inside of a solid leaving a shell of specified wall thickness.• Needs a 3d shape

DO 1

• Create a new Standard(in).ipt• Turn on visibility• Create a new sketch on the XY Plane

DO 2

• Create a circle that uses the center point as the center point• Circle is of arbitrary

size

DO 3

• Use the line tool to add the three segments shown. • Note where the

center point of the circle is• Trim the rest of the

circle

DO 4

• Add the two dimensions shown• DO THE

HEIGHT DIMENSION FIRST

DO 5

• Add a R.25 fillet to the top right corner• Finish the

Sketch

DO 6

• Do a revolve around the 1.5 in vertical line

DO 7

• To add offset work planes, click the Plane button arrow, and choose Offset from Plane

DO 8

• Select the XY Plane• Type 2.5

and click the checkmark

DO 9

• Repeat with a 3.4 and a 4.25 plane off the XY Plane• Create a new

sketch on the XY Plane.• Press F7 to see

inside the bowl shape

DO 10

• Draw a rectangle with the bottom left corner on the origin• Add the

dimensions shown• Fillet the corners

R0.25• Finish the sketch

DO 11

• Create a new sketch on WorkPlane1• Set the View to

Wireframe with Hidden Edges (View tab of the ribbon

DO 12

• Click Project Geometry• Click the bottom edge

rectangle we just drew to bring it’s geometry forward• Draw the new

rectangle shown keeping the lower RIGHT corners aligned• If this doesn’t make

sense, ask for help

DO 13

• Repeat the above steps with WorkPlan2 and WorkPlane3

DO 14

• Now we are going to create a loft• Click Loft on the

ribbon• Click inside the

sections box• Click each of the

four sketches we just made• Then click OK

DO 15

• Change the view back to to Realistic, and you’ll see the finished Loft• Change back to

Wirefram with hidden lines• Create a new

sketch on the YZ Plane

DO 16

• Draw the shape shown, • Add the three

dimensions• Finish the 2D

sketch

DO 17

• Extrude the shape 5.5• Change the view

back to Realistic• It should look like

mine

DO 18

• Add a fillet along the 3 edges of R0.15

DO 19

• Flip the drawing over• Click Shell on the

ribbon• Click Remove

Faces arrow, click two faces shown• Set the thickness

to 0.125• Click OK

ALMOST THERE

DO 20

• Create a 2D sketch on the top face of the part.• Draw a two-point

rectangle on the side, as shown

DO 21

• Add the dimensions as shown• Finish the sketch• Extrude it 0.13

down as a CUT• It’s just going to

make a little knick on the part

DO 22

• Click rectangular pattern

• Click the knick as the Feature

• Click the Direction 1 Arrow, and choose the bottom horizontal line

DO 23

• Set the Number of Direction 1 to five• Set the spacing to

0.6

DO 24

• Set the direction 2 arrow as the verical line on the bottom right corner of the shape.• Set the number

to 10 and the spacing to .25• Click Ok

DO 25

• Save your work as D11.shell• There are no

exercises for this assignment• D12 is optional,

but bending sheet metal is interesting
