Autopitch

Create weld points at a predefined pitch distance so that the model build process can continue without the need to wait for the published weld data from CAD.

Figure 1. . Starting with a CAD model, the Autopitch tool creates unrealized connectors (yellow) which are then realized via the Spot panel.

1. From the menu bar, click Connectors > Create > Autopitch.
   The Autopitch dialog opens.
2. Using the Components selector, select the components to automatically add connectors to.
   All selected components receive connectors with the same qualities to help you perform a blanket application of connectors-using the same pitch-to all components that need them as a single operation. Be wary of simply selecting the whole model, however, as this could result in undesirable actions, such as adding welds to a cars tires.
3. To use shell meshes that enclose a volume (some small gaps are allowed) as input, enable the Consider closed shell thin solids checkbox.
   For example, the outer skin of a solid part can be shell meshed and used as input to create connectors. Standard mid-plane meshes are also still considered when this option is used.
4. To create connectors in the middle of the found flanges, enable the Create in middle checkbox.
   By default, connectors are created on either one of the flanges. This applies to both mid-plane and closed shell thin solid inputs, when appropriate.
5. Define settings.
   1. In the Search distance field, enter the distance to consider between components.
   2. In the Spot pitch distance field, enter the distance between each connector.
   3. In the Spot pitch end offset field, enter the distance from the end of an edge/flange to the connector.
   4. In the Distance from free edge field, enter the distance from the free edge to the connector.
   5. In the Feature angle field, enter the angle used to segregate the model into faces that are planar within its specified value.
   6. In the Max deviation from avg dist (%) field, enter the average distance that can be calculated based on the estimation that the distance between two flanges does not change too much in the areas where connectors should be placed.

      If the distance at the position where a connector is planned exceeds the given deviating value, no connector will be created at that position.

      This segregation is used to identify where autopitch connectors are placed. For example, faces found to have significant topological complexity are not used to create autopitch connectors.

      Note: By reducing its value, the complexity of some of these faces is generally reduced. Of course, flat regions are unaffected by the parameter.
6. Click create.

The created output is a series of connectors with the appropriate pitch distance and other associated parameters. These connectors are in the unrealized state, thereby allowing the connector to be realized to a configured state.

The output is organized in the current component collector. If there is no current component collector, then a new collector called ^autopitch is created.
