Join Jim LaPier for an in-depth discussion in this video Creating and working with 3D objects, part of Up and Running with Vectorworks.
We spent much of our time using polygons and poly lines to create complex shapes, and now we'll put that work to use by extruding our objects into a 3D shape. The first tool we'll use to convert our 2D objects to 3D is the Extrude tool. Here I have a 2D gear that I've created using polygons. I'll select it, and go to Model > Extrude. I'll enter a value of 0.5 for the extrusion height and click OK. Let's switch to an Isometric view. And I'll turn on OpenGL to get a better sense of the object.
While still in isometric, I want to mention an aspect of the Extrude tool. If I select multiple surfaces, like the circles here and go to the Extrude tool. I'll give them a value of one. All three of these objects, while not connected, were extruded as a single object. Meaning, they're one object now. Keep this in mind, if you need to extrude multiple objects, separately. Next, let's look at sweeping an object, like the shape I have here. Before sweeping, I need a point to sweep around. In this case, I'll use the Locus Point tool here.
And add a point on the axis, right about here. I'll return to my Selection mode, use the Shift key to add the original polygon. And now I'll go to Model > Sweep. For this sweep, I only want to rotate the object 135 degrees. But I also want it to travel down away from me. So I'll enter negative 135 degrees, here in the arc angle. I'll click OK, and there I have my sweep. For the circle and rectangle here, I want to create a rod with a key slot missing from the top.
I'll extrude the circle by two units and now I'll rotate around. Select the rectangle, and extrude it by 0.5 units. Click OK, and now I have my key. Unfortunately, the key right now is at the bottom of the rod. I need it to be at the top. Go to Switch, to a Right view, select my key and drag it up. I use Tab to enter the value enter mode. And tab over, make sure that delta x is set at 0 and delta y is 1.5.
I'll hit Return and Return again to confirm. And now my key's been moved to the top of the rod. going to switch back to an Isometric view. I'll use Shift to select my cylinder and add it to the selection set. And now I'm going to go to Model > Subtract Solids, a small dialogue box appears with arrows on it that allow me to choose which object I want to subtract from, again this is the object I'm going to retain. So I'll make sure that this cylinder is the one highlighted, press OK. And my key has been subtracted from the rod.
Working with 3D object can be daunting as we're adding a third dimension to an already expansive drawing environment. Practice these tools and soon you'll be more comfortable with working with 3D objects
