Most SigmaNEST clients prefer to autonest their jobs as it saves them time, money and a lot of unnecessary effort. For the ones that don’t here are a few advanced nesting functions that can speed up your manual nesting process.
Parts can be manually pre-nested when creating a new nesting task. To pre-nest the parts, they must be added to the task list on the right side of the Task Setup dialog box.
Pre-nesting is used to combine parts into a group that can then be nested as a group of parts in a specific orientation.
For example, if you had multiple parts that you wanted to nest as a ‘L’ shape, you can build the shape manually by pre-nesting the parts as a group. Next, when the parts are nested onto the sheet, the parts you pre-nested in the group are placed on the sheet in the ‘L’ shape.
Keep in mind that you cannot pre-nest parts if the requested part quantity is reached, or if the nest runs out of sheet space.
How does it work?
- From the Task Setup dialog box, click Pre-nest. The Pre-nest window opens with the parts from the task listed on the right. By default, the Pre-nest group is set to Group 1.
- Click on the part you want to pre-nest and drag it out to the pre-nesting workspace. You can use the action buttons on the left to set the pre-nest options, such as rotation, alignment, torches, mirroring, and bump settings.
- Perform any of the following actions as necessary:
- Click New Group to save the current group, clear the pre-nest workspace, and open a new group workspace. Arrange the parts for this new group and repeat this step for each group you want to create.
- Select a group from the Pre-nest list to view an existing pre-nest group of parts.
- Select a group from the Pre-nest list and then click Delete Group to remove the part grouping.
- Click Move and then select a part on the workspace to move it to a new location.
- Click Copy and then select a part on the workspace to create a copy of the part. Drag it to a new location and click to place the part. Press the Esc key or click Copy again when you are finished copying parts.
- Click Remove Parts and select the parts to remove. Right-click or select the check mark icon to the left to remove the parts from the workspace.
- Click Move Leadin to manually reposition the part leadins. Click a part to select it and then click a position on the part to place the leadin. Click Exit () or press Esc to save your changes and end the function.
- Click Close to save the changes and return to the Task Setup dialog box.
- Now you can manually nest each group. To save the pre-nest for future use you can save it as a Static Nest.
Static Nests are saved sheets with the parts already nested. You can save automatically or manually created sheets as static nests.
Save a Static Nest
- From the Nesting tab, in the Manual Nest group, click the arrow under Static Nest.
- Select one of the following save options:
- Save Static Nest. Saves the current nest as a static nest. In the Save As dialog box, enter the File name for the new static nest and then click Save.
- Save Static Nest as Kit. Saves the current nest as a static nest as a kit with multiple sheets. In the Save As dialog box, enter the File name for the new static nest and then click Save. This is typically used when parts on multiple sheets make up one complete item when cut and assembled, such as furniture.
- Save Static Pre-Nest. If you pre-nested parts as a group for the sheet, this option saves the pre-nest as a static nest. In the Save As dialog box, enter the File name for the new static pre-nest and then click Save.
Load a Static Nest
- To load a static nest, click the arrow under Static Nest and select Load Static Nest. The Static Nest dialog box opens and displays a list of all static nests. Select a static nest from the list to view the parts associated with it.
- Enter search criteria into the Part Name, Material, and Thickness text boxes to search the Static Nest List.
- Click Rebuild to take the files in the static nest and import them back into the database.
- Select the static nest to load from the list and then click Load. Click Yes when prompted to load the static nest. The Confirm dialog box opens.
- Select one of the following methods to determine how the parts in the static nest are added to the nesting task when loaded.
Include Parts. Includes all parts in the static nest in the new task. The sheet is populated with the parts and NC paths from the static nest. The parts are also displayed in the Parts Bar.
Exclude Parts. Loads the NC paths from the static nest to the new task but does not add the parts to the task. If any parts from the static nest are not in the new task, the parts are not nested on the sheet. If you clear the NC, all NC
