What is the Pattern tool?
A Pattern FB makes an array of one or more Solids. 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. |

Add Pattern FB
|
Modeling FB toolbar > Pattern FB |
|
Menu : |
Add menu > Add Pattern FB |
|
What to do : |
STEP 1.Add the Pattern FB to the graphic-area
The Pattern FB is now in the graphic-area and the Assembly-Tree. |
|
How to Edit : |
STEP 2.Open the Pattern dialog-box
The Pattern dialog-box is now open. STEP 3.See Pattern dialog-box |
|
Preparation : |
Add Solid elements to the model. The Pattern FB can make a pattern of Solid elements Use Visibility toolbar > Show Solids in Mechanisms to see the Pattern of the Solids |
|
Notes : |
A simple application of the Pattern element is to show or hide a single Solid at different machine angles in the machine-cycle. |
Note: Pattern FB and a Driving Pulley:
If you want to make a Pattern of a Solid element along the complete belt-length, 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.
