Bottle – using Surface Features

Pro/ENGINEER Wildfire 2.0

Dr Herli Surjanhata

Create a part named bottle with three default datum planes and default coordinate system Make sure the Units is in millimeters

To change the units,

From Edit pull down menu, select

Setup -> Units

Select millimeter Newton Second (mmNs)

Set and select Interpret Existing Numbers (Same Dims)

Click the OK button

Close -> Done

Pick the icon to create a sketched datum curve on the

FRONT datum plane The dimensions for the datum curve shown in Figure below

Pick Right datum plane as

Mirror plane

Pick the button to

complete the task

Mirror the datum curve about the RIGHT datum plane

Select the datum curve in the Model Tree or graphic area, then choose Edit -> Mirror

Repeat the same procedure to create another datum curve

Create a sketched datum curve as shown

in the Figure below Sketch on the

RIGHT datum plane with TOP as the top reference Make sure it is 140 mm

height, the same height as the other curve

Mirror the last datum curve about the FRONT datum plane The resulted curves are shown in the Figure below

Create a sketched datum curve as shown

in the Figure below Sketch on the TOP

datum plane with RIGHT as the right reference

Pick the icon,

Move the Sketched Datum Curve dialog

box to reveal the icon needed to

create datum plane for sketching

To create a datum plane on the fly, pick the icon, and DATUM PLANE dialog box apprears

Pick the TOP datum plane, and enter the offset translation 140 mm as shown below

Pick the OK button.

Click the Sketch button

Create a sketched circular datum curve

as shown in the Figure below

The resulted datum curves are shown below

The datum curves created above will be used to create surface feature Select

From Insert pull down menu, select

Boundary Blend …

Click the Curves option as shown below

Pick the four vertical datum curves shown on

the right figure – After picking the first curve,

press Ctrl key while selecting the rest of the

curves

Make sure to check the Closed blend box

Click the box (Click here …)

under Second direction for the

2nd direction chain collector

Pick the top and bottom (circular) horizontal

curves

Select the to finish the surface creation

The resulted surface is shown in the Figure on the left

Create another surface at the bottom by selecting Edit pull down menu, then choose Fill …

Pick the bottom curve

Select the to finish the surface creation

To merge the two surfaces, select two

the Merge Tool icon on the Features toolbar or click Edit -> Merge

Pick , then select Join

Select the to finish

Pick the Round Tool icon to create a round of 5 mm radius at the bottom edge

of the surface

Pick the bottom edge of the bottle

Click the icon to finish

To create a thin solid from a surface quilt, Select the surface quilt first

then Edit -> Thicken

Enter thickness 1.5

Click the button to continue

Select all datum curves, then right click mouse button and choose Hide.

Create the cylindrical cut as shown below

Pick the button, then pick

the Remove Material button, followed by clicking the ->

For sketching plane select DTM1 in the Model tree,

Pick the Sketch button Make the cut with the following information:

Diameter = 19.5 mm Depth = 15 mm

Be sure to cut the outside the part

Create a HELICAL SWEEP for the thread

The length of the profile is 8 mm, and see figure on the left for other dimension

The section of the thread is shown below

Pitch = 4 mm

Create a revolved protrusion to smooth out the top end of screw thread

For sketching plane, select the end plane of the top end part of the thread – see figure below, and revolve it at 55 degrees

Pick this plane

as sketching plane

The resulted feature is shown below

Sketch a centerline

as axis of revolution

Use Edge of the end thread for the section to

be revolved

Pick this plane as sketching plane for another revolved protrusion

Repeat the same procedure as shown above to create a revolve feature for

smoothing the bottom part of the thread

See Figure below for dimensioning

Finally create necessary rounds to eliminate the sharp edges

Axis of revolution
