3D Drawings

Sample Shapes

The following simple examples show the key methods of making 3D shapes. You can also use these diagrams to get started on a design by finding the shape closest to what you need.

When reading the Z values in the diagrams, consider that the distance across the 2D front view is generally one inch.

washer_3d

washer_2d

To create a simple flat washer using milling create two circles and set the Z value of each circle as shown.

To create a washer using a 2D process (e.g. router) draw the same way but there is no need to set the Z values.

five_side_box_3d
five_side_box_top
To create a five side box, draw a rectangle. Line | Corner | Round. Line | Contour | Inner. Set Z values as shown. Side holes and cutouts can be added in side views.
3
pipe_holes_3d pipe-holes-top_1pipe_holes_front


To create a pipe with side holes draw concentric circles in the top view and set Z values as shown. In the Front view draw the hole circle and set Z as shown. The light colored lines are created automatically.

4
pipe_spacer_3d
pipe_spacer_toppipe_spacer_front
To create this pipe spacer draw a circle in the Top view and set Z as shown. In a side view (e.g. Front) draw the shape shown by the dark line and set Z to Air Outside. The Air Outside setting specifies that all material outside the line should be removed.
5
shaft_clamp_3d
shaft_clamp_topshaft_clamp_back

To create a shaft retaining clamp:

  1. Choose View | Top.
  2. Draw the shape shown by the bold line.
  3. Set Z as shown.
  4. Choose View | Back.
  5. Draw a circle for the retaining screw.
  6. Choose Line | Machine | Thread and select the desired thread.
  7. Set Z to slightly more than the length of the screw.
  8. Create the outermost circle for the unthreaded bore using a diameter slightly more than the screw size.
  9. Set Z to the depth of the unthreaded portion.
  10. Choose View | Top.
  11. Verify that the light projection lines are as shown.
6
pulley_3d
pulley_top

pulley_front

To create a pulley, create a circle in the top view and set Z as shown. In the Front view draw the cross section to be revolved (the dark line) and set Z to Revolve. The light colored rectangle and center line are created automatically. The revolved shape must be to one side of the center axis and must touch 3 sides of the rectangle.


7
pawn_3d
pawn_toppawn_front
To create a chess pawn, create a circle in the top view and set Z as shown. In the Front view draw the cross section to be revolved (the dark line) and set Z to Revolve. The light colored rectangle and center line are created automatically. The revolved shape must be to one side of the center axis and must touch 3 sides of the rectangle.

gear_3d
gear_top
To create a gear choose File | New | Gear.
9
sheet_metal_box_3d
sheet_metal_box_2d

To create a sheet metal box, choose File | New | Box.

To create other sheet metal designs with bends:

  1. Draw the flat shape (something like shown here).
  2. Multiple select the above lines.
  3. Draw straight lines where you want bends.
  4. Multiple select the above lines.
  5. Choose Line | Machine | Bend.

front_panel_3d
front_panel_2d
To create a front panel, draw the outer rectangle, inner cutouts and mounting holes if needed. Choose Job | Finish and consider adding one more more finishes such as brush, anodize, powder coat, etc. On the left toolbar choose the text button and add text labels for controls. Choose Line | Machine | Silk Screen to assign the text for silk screen printing.
11
hole_types_3d
hole_types

Note: The Z value for the square block is assumed 0.5 in these examples.

To create a thru hole draw a circle and set Z to Air Inside.

To create a countersink: draw a circle; set Z to Air Inside; choose Line | Machine | Auto | Chamfer and select the desired settings. For the angle use 90 minus head angle / 2. For example, for an 82 degree head use (90 - 82/2 = 49). Adjust the chamfer size so the side view fits a drawing of the flat head screw which you can make using Comments To Myself. (Using a chamfer size of (head diameter - screw diameter) / 2 does not account for recessing the head or any rounding at the edge of the head.)

To create a counterbore, for the outer circle set Z to minus the bore depth.

To create a blind hole, set Z to a negative value less than the overall part depth.

steppedrecess21
steppedrecess12

To create a recess or protrusion adjacent to a curved shape proceed as in this example.

Note: Z = 0.4 for outer rectangle in this example. And suppose that the Z = -0.2 notch is not yet drawn.

  1. At the location of the notch draw a rectangle extending past the left edge of the outer rectangle and past the large arc.
  2. Choose Edit | Select All.
  3. Duplicate via Edit | Copy, Edit | Paste.
  4. Nudge the copy fully away from the original, using the arrow keys.
  5. Choose Line | Intersect.
  6. Remove all lines except the shape corresponding to the arced notch.
  7. Group the lines of the notch.
  8. Set Z to -0.2.
  9. Delete the original notch rectangle.
  10. Nudge the arced notch into place.

13
Shape_13_3d
shape_13_2d

To create a "foot" on an outermost part surface proceed as in this example (we assume the circle is already drawn but not the foot):

  1. At the location of the "foot" draw a rectangle extending inside the outermost circle.
  2. Choose Edit | Select All.
  3. Duplicate via Edit | Copy, Edit | Paste.
  4. Nudge the copy fully away from the original, using the arrow keys.
  5. Choose Line | Intersect.
  6. Delete large arc and straight segments inside the circle.
  7. Group the lines of the "foot".
  8. Set Z to -0.75.
  9. Select original rectangle and circle.
  10. Choose Line | Intersect.
  11. Delete small arc and straight segments inside the circle.
  12. Group the lines of the boundary region and set Z to 0.8.
  13. Nudge the "foot" into place.
