|Using grids lets you position structures more easily as well as design in context. You can create structures referencing geometrical grid elements. Design changes can then be introduced by modifying the grid and updating the structure in consequence.|
|This task shows how to
create a new grid that you can then use as a construction aid to create
A grid is made of wireframe elements (lines, points and planes) and is identified in the specification tree. It can be created using either the Cartesian or Polar coordinate system.
|1.||Click the Grid
The Grid Definition dialog box appears.
Enter a name for the grid you want to create in the Name box:
The grid will be identified by this name in the specification tree.
Select Relative or Absolute in the Mode list
to define the grid construction mode.
|4.||Enter absolute coordinates in the Origin box or select a point in the geometry area to define the grid origin.|
|If you select a point, the point is identified in the dialog box. The grid origin is now linked to this point.|
In the First direction in XY plane box:
Note: By default, the local x-axis is positioned along the absolute x-axis.
|If you select a line, the line is identified in the dialog box. The first direction is now linked to this line.|
Specify grid coordinates:
|Note: Clicking More expands the dialog box and lets you enter up to three more different combinations to define your grid.|
|7.||Click OK to create the grid.
The grid is created and is identified in the specification tree.
|Grid planes are associative: moving a plane will update the grid.|
|This is useful when modifying a structure:
move a plane (double-click to edit) and see the structure defined using
the grid updated when you double-click the root product in the
specification tree if the following options were set in the General tab
in the Options dialog box (Tools -> Options, Infrastructure -> Part
