Using Cells in 3D

Cells are used in 3D modeling in a manner similar to 2D. You can place a 2D cell in a 3D model and vice-versa. When a 3D cell is placed in a 2D model, it is placed as a Top view orientation. That is, with its X and Y design axes matching that of the 2D model's X and Y design axes.

Creating 3D Cells

The procedure for creating a cell in 3D is similar to that in 2D (see Creating and Editing Cells), with these differences:

  • 3D cells, along with their 2D counterparts, are simply models in a DGN file that have the setting Can be placed as a cell turned on.
  • In 3D, the cell retains the orientation in which it was created. For example, a cell created in a Top view always is placed as though it is a Top view. That is, its length and width always would be along the x and y axes of the view (if AccuDraw is not active) or the AccuDraw drawing plane (when AccuDraw is used). Normally, cells should be created in one of the Orthogonal views to simplify future placement.
  • 3D cells are created in a volume determined by the fence area and the view's Display Depth.
Note: It is a good idea to create separate models of those objects that you later want to use as cells.
