SHEET METAL CORNERS Purpose
Objectives
• Creating a flat solid version of a sheet metal part is an interim step between the formed part and the flat pattern used for drawings and later manufacturing.
• Upon completion of the lesson, you will be able to:
• The Flat Pattern command in Sheet Metal provides many options for displaying sheet metal features.
• Create a Flat Solid and a Flat Pattern of the sheet metal part. • Become familiar with the sheet metal preferences available for displaying and modifying the flat pattern view.
Flat Pattern • Use the Flat Pattern command to create a 2D representation of a 3D sheet metal part. You can: • Include annotations for bending, punching, or cutting manufacturing instructions. • Export the flat pattern data to a cutting tool for the manufacturing of the part. o You can use the Export Flat Pattern command to export flat pattern curve data to a DXF file or a Trumpf GEO file. The exported flat pattern curve data is non-associative. • If you export a drafting flat pattern view using the File tab→Export→Part command, the exported drafting flat pattern view is non-associative.
Flat Pattern • Occasionally, the curves representing the exterior boundary, or interior cutouts in the Flat Pattern view are incorrectly classified if the sheet metal model has a deform feature such as a dimple or a bead on the model boundaries, cutouts across deform features, or cutouts that have chamfered edges.
Tips for working with flat patterns • You can view the Flat Pattern features that you create in one of these ways: o In the Part Navigator, expand the Model Views node. If you delete the feature, the Flat Pattern view is also deleted. o In the View → Layout → Replace View dialog box, select the Flat Pattern view. • You do not need to create a Flat Solid feature first. The Flat Pattern command will automatically create the Flat Solid and make it internal to the Flat Pattern feature. To make the Flat Solid feature external, in the Part Navigator, right-click the feature, and choose Make Flat Solid External.
Tips for working with flat patterns • You can add the drawing view onto a drawing sheet for drafting. • You can use the Bend Table command to insert a bend table in a drawing that you create using the flat pattern view of the Sheet Metal part. The tabular format makes the bend information easy to read in downstream applications.
Summary: Flat Solid and Flat Pattern • The Flat Solid command physically alters your part in shape and material attributes. You can use this command to prepare your part for manufacturing. • The Flat Pattern command lets you incorporate system and user-defined elements into a model view and a drawing sheet for use in the manufacturing process. • In this lesson you: • Identified the key elements necessary to create Flat Solid and Flat Pattern features. • Created Flat Solid and Flat Pattern features.
