A Pattern FB makes an array of one or more Solids that is in the model. A Pattern is similar to a circular or linear array as found in your CAD. However, the Pattern FB must anticipate the motion of each Solid in the array at each instant in a machine-cycle relative to the other Parts in the model When you use Pattern FB to hide a copy of a Solid at phases in the machine-cycle, you also remove its Mass-Properties. |

What to do: |
STEP 1Add the Pattern FB to the graphic-data
The Pattern FB is in the graphic-area. |
||
STEP 2Open the Pattern dialog-box:
The Pattern dialog-box is now open. STEP 3See Pattern-FB dialog-box. |
A Driving Pulley is one in which the motion is applied to the Pulley and not to the Belt. If the timing is such that the Pulley makes one rotation in a machine-cycle, the Belt will not complete its motion along the sketch-loop in one machine-cycle. If you want to use a Pattern FB to model an array (Pattern) of a Solid element to be along the complete length of a Belt, you must make changes to the timing of the Pulley. 1.Add a Gearing FB to the input-connector of the Motion-Dimension FB that is driving the Pulley 2.Open the Gearing FB dialog-box 3.Make the Gearing Ratio = Belt-Length / Pulley-Circumference. The Pattern of the Solid elements should now be at equal spaces along the complete Belt-Length. |
