In addition to using copy and paste in the graphics window, you can copy one or more parts using the browser. In the assembly browser, click the icon of the part or assembly and drag to the graphics window. A copy is created and added at the bottom of the browser tree.
To copy multiple components, hold down the CTRL or SHIFT keys and select in the browser, and then drag to the graphics window.
In the browser, drag the End of Part stop sign to the top of the browser hierarchy, then drag downward feature by feature. Each feature is recreated in the order listed in the browser.
Use the Split part command to divide one part into two. By default, Split removes one side of the split part, but you can save each with a unique name. Save the original part, then remove one half, and save with a unique name. Re-open the original part, remove the other half, and save with a different name.
In a complex model, it is sometimes easier to select geometry in the browser than in the graphics window. In the browser, highlight the geometry you want to align parallel to the screen and use the View Face command. The model rotates to show the selected geometry. For example, select an origin work plane to realign the model to view a part face.
When a decal must span across parts in an assembly, create a thin part (such as a surface) and place the decal on the part. Size the part to match the decal size. Use assembly constraints to position the decal part in the assembly. If the decal is used repeatedly, create iMates to simplify decal placement.
