Pattern Tool in the Modelling-FB Toolbar

Use the the Pattern FB to make multiple copies of a Solid in space and time.

The Pattern tool is very powerful. You should experiment with it!

You can use the Pattern element in one of two ways:

Space Pattern

- or -

Phase Pattern

In this Step, we use a 'Phase Pattern' to model multiple copies of Solids moving along a path.

We use a Pattern FB to show multiple copies of a Solid, with each copy moving along the same path and motion as that of the 'source' Solid.

Add and Edit the Pattern FB:

tog_minusAdd the Pattern Element to the Assembly Tree


1.Click Modelling-FB toolbar > Add Pattern Tool
2.Click the graphic area


MechDesigner adds the Pattern Element to the Assembly-Tree.

tog_minusEdit the Pattern Element


1.Right-click the Pattern Element in the Assembly-Tree.
2.Select 'Edit...' in the contextual-menu.

The Pattern Element dialog-box opens.

tog_minusThe Pattern Element


Before you enable the Pattern element, set the Auto-Update tool to 'Do not Auto-Update'.

The pattern element uses a lot of CPU. This slows selection processes.

Double-click the Pattern element in the Assembly-Tree.

1.Select the Enable check box1s-red.
2.Select the Phase Pattern radio button2s.

Phase Patterns apply to multiple copies of the same Solid for the 'Path' that the Solid follows in a machine cycle.

Reminder. Solids are:



Files imported from SOLIDWORKS, or other CAD, onto a CAD-Line.

3.Select Extrusions and those CAD-Lines onto which you have imported a SOLIDWORKS file.

The Extrusions and CAD-Lines show in the Pattern Elements box3s

4.Use the Spin-box or your keyboard to enter the number of copies along the Path4s

Enter 12 Copies.

This is because the Slider-Set 2 leads Slider-Set 1 by 30º.  To fill the chain with links, we will need 12 copies. (360/30 = 12)

Each copy, and its phase, shows in the box7s below.

5.Click the 'Hide the Source Element' check-box5s (recommended)
6.Make the Pattern Range = 360º.6s

We enter 360º because we want to show each Solid along the Path during a complete machine cycle.
