You can create a rotary relief from a 3D object
in the Project Tree.
To create a rotary relief from a mesh:
- In the
Project panel, right-click the 3D object
in the Project Tree from which you want to create a relief.
- Select Create Rotary Relief from the context menu.
If the mesh is found to contain an inner-diameter and is currently aligned with either the Y or Z-axis, a message dialog is displayed confirming that the mesh is recognised as a ring and asking if you want to align the resulting rotary relief with the X-axis of the model:
- If you no longer want to create a rotary relief from the mesh, click Cancel.
- To align the resulting rotary relief with the X-axis of the model, click Yes. The message dialog is closed and the relief creation process continues.
- If the mesh is not a ring or you do not want to reposition the resulting rotary relief, click No. The message dialog is closed and the relief creation process continues using the current orientation.
A set of two relief layers is created from the mesh. If a flat model is currently open or there is no model currently open in which to create these relief layers, a new model is created in the Project Tree first. The model is given the name of the mesh.
The highest triangle in the mesh is converted into a new relief layer at the top of the layer stack that builds the composite relief representing the front surface of the piece, while the lowest triangle in the mesh is converted into a new relief layer at the top of the layer stack that builds the composite relief representing its back surface.
Where there is a distinguishable inner-diameter in the mesh, ArtCAM creates a rotary relief in which the X dimension is equal to the inner radius and the Y dimension is equal to three times the width of the ArtCAM model containing the ring.
Where there is no clear inner-diameter in the mesh, ArtCAM creates a rotary relief in which the X dimension is equal to the outer radius and the Y dimension is equal to the width of the ArtCAM model plus a border equivalent to 10% of its original size. The base height is equivalent to the radius of closest point to the world centre.
Both of the relief layers adopt the name of the mesh, with the Top suffix applied to the layer associated with the front surface of the piece, and the Bottom suffix applied to the layer associated with its back surface. Each layer is visible.
The Merge High relief combine mode is applied to the layer associated with the front surface of the piece by default. The Merge Low relief combine mode is applied to the layer associated with the back surface of the piece by default.
