Mac Instructions

Windows Instructions

Open Rhino and click Show Templates on the right

Open Rhino and click the New Tab at the top

Scroll down in the template menu and choose Small Objects - Millimeters

Scroll down in the template menu and choose Small Objects - Millimeters

STEP 1: Draw a box (with all dimensions the same), a circle, and a polyline. They can be anywhere and be any size but make sure the box with all sides of a consistent dimension.

STEP 2: Scale the box to be exactly 10mm in every dimension

  •  In the command line, type “scale” and press ENTER

  • Select the Box and Press ENTER
  • Origin Point: Mouse-click on one corner of the box (you need to have Object Snap On)
  • Scale Factor: Mouse-click on another corner (but not a diagonal)

  • 2nd Reference Point: Type 10 and press ENTER

STEP 3: Change only one dimension of the Box.

  • In the command line, type “scale1D” and press ENTER

  • Select the Box and press ENTER
  • Origin Point: mouse-click on one corner of the box (you need to have Object Snap On)
  • Scale Factor or First Reference Point: mouse-click on another corner (but not one that is diagonal).
  • 2nd Reference Point: Type 4.5 and press ENTER

The box is now 4.5mm wide while the other dimensions are still 10mm

STEP 4: Scale circle to exact dimension (5mm radius)

  • Make sure the object snap for center and intersection are turned on.
  •  In the command line, type “scale” and press ENTER

  • Select the Circle and press ENTER
  • You need to hover near the circle’s edge to find the center Origin Point.

(optional: I added a radial dimension so I could see the changes file menu:  dimensions>radial dimensions)

  • First Reference Point: mouse-click on a point on the circle’s curve (the tooltip will say “near” or “intersection” or “end”) and mouse-click
  • 2nd Reference Point: Type 5 and press ENTER

STEP 5: Orient the line to the box

Type “orient” into the command line.

  • Select your polyline.
  • Mouse-click one end of the polyline (reference point 1)

then mouse-click the other end of the polyline (reference point 2)

  • Click the bottom corner of the box then click the top diagonal-corner of the box.

STEP 6: Scale the line to fit the box.

Type “scale” in the command line.

  • Select the polyline and press ENTER.
  • Mouse-click one end of the polyline, then the other end.
  • Drag the endpoint to the upper corner of the box and mouse-click

Now that you know how to precisely scale….get scaling!

Congratulations!!!
