New for SolidWorks 2013 is the capability to store library features as multi-body files. This works great for adding plates and mounting feet to weldment part files. The process for making one of these library features couldn’t be easier. I’m going to walk you through the steps for making a foot plate to insert inside of a rectangular structural profile.
First you want to make a base extruded feature in a new part to simulate the type of placement you will have for this foot plate. Next you will model the foot plate and place it inside of the first profile. I have also added some chamfer features that can be controlled at the design library level as well as a tapped hole to allow fasteners at a later time.
Be sure to make this second extrude its own body by unchecking the Merge Result box.
Second, you will choose to add this to the design library folder of your choice. Give it a name and description for ease of use by your co-workers when they need to add this to their designs.
Next, you need to edit this library feature and setup some conditions. In this image we are choosing the references for placing the foot plate inside of the tube.
I have a face selected for placement and 4 edges to allow this plate to grow and shrink based on the size of profile I am attaching this to.
Finally you need to choose which dimensions are presented to the user and which ones are hidden. You do this by dragging dimensions from the Dimension folder to either locating dimensions or internal dimensions.
Re-save the file and you are on your way. You can then use this in any part weldment that contains 4 edges to locate to.
