Battery Plate, Advanced Extrusions and Fillets

by

In this lesson the students learn how to use a CAD program to produce a new part using an existing part's design. We want to make a "Battery Plate" to sit on top of the battery that we just made in the previous lesson and we want to use the same overall size and design. We'll explore advanced features in sketching and in creating new types of fillets. We are doing all this to create a 3D model of a 6-volt battery and plate, the kind you would use in a large heavy-duty flashlight. The students will use a CAD program to do this (SolidWorks), but other CAD programs can be used.

Introduction

Students have created a 3D model of an actual 6-volt battery like the type used in a heavy duty flashlight. That was the first part of an 8-part flashlight. We will now create a plate to be placed over the top of the battery, see pictures below. The Computer Aided Drafting (CAD) software will be used by the students to take an existing part, the battery, and save it as a new part, the plate. They will then learn how to change the features of the old extrusion and create a short plate of the same design characteristics as the original battery. They will learn how to use "Instant 3D" features and will also learn how to create advanced fillets including differing radius fillets (rounds) as well as full round fillets.

This lesson and project will concentrate on Solidworks but other CAD programs can be substituted if they are truly 3D modeling software.

  • Save an existing part in CAD software so that a new part with some of the same design features can be made.
  • Change an existing 3D feature such as an extrusion to change it's length and other characteristics.
  • Use the instant 3D feature to create a cut from an existing 2D sketch entity.
  • Create advanced fillets (rounds) including multiple radius fillets and full round fillets.
