Creates a 3D object between two 2D objects that lie on different planes. The planes do not have to be parallel.
Both profile objects must be the same type and must have the same number of vertices. For example, you can create a prism between two circles or two rectangles, but not between a circle and a rectangle. Splines and Bezier curves must have the same number of control points.
(If you want to use more than two profiles, or profiles of different type, see Profile Objects.)
...
Note: A prism is considered to be a Lofting object, and its Properties contain a Lofting Shape page. For details, see Profile Objects.
...
- If you want to select only simple (single-object) curves, make sure Use Compound Profile is not selected. If you want to use compound profiles, see Profile Objects.
- Select the two 2D objects.
Polyline to polyline
Spline to spline
You do not have to select closed 2D objects. If you use open objects, a 3D surface will result.

A compound profile is an open or closed chain of connected curves or lines. You can use compound profiles when you do not want to create a polyline, or convert a chain into a polyline. - Make sure Use Compound Profile is selected.
- Select the first compound profile, which is automatically identified as a chain. To deselect any curve in the chain, select it again (it will turn green). In this example, Profile 1 is a series of connected lines, not a polyline.
- When the profile is selected, click Finish Selection of Profile, or select it from the local menu.
- Select the second profile using the same steps.
- When you finish the second profile selection, the prism is created.

Available in TurboCAD Pro and Platinum only_
Pulls or pushes a 3D extension of a face by extruding 2D a closed area on the face of a 3D object. The extrusion extends along a path normal to the face of the 3D object.
The closed are must be coplanar with the Flat face of a 3D object. It may consist of:
Any closed 2D entity. E.g. a rectangle
Any area that can be hatched by picking a point (with zero gap tolerance)
Areas enclosed by crossing coplanar, linear geometry, including edges and geometry in blocks E.g. intersecting lines that create a closure
3D faces. E.g. The face of a cube
Any combination of the above. Areas created by geometry (including edges on faces) drawn coplanar to any face of a 3D solid E.g. A circle is coplanar with the face of a cube. It overlaps the edge of the cube. The edge divides the circle into two parts, one is a valid area, or intersecting lines that create a closure on the face of a 3D object, with or without defining geometry of the 3D entity.

Creates a 3D object by driving a 2D profile along a path.
...
Available in TurboCAD Pro, Platinum and Deluxe Only_
Creates a 3D object by driving a 2D profile along a path. The profile and path do not have to touch or be in different workplanes; the profile section will be "brought" to the start of the path, made normal to the path, and swept along it.
If you are going to use Compound profiles for both the path and the profile you will need a base point. The base point specifies the point though which the profile will follow the path. To create a base point, use the Point tool and place a point at the location adjacent to the profile that you wish to be used. For example, at the end of a line, or at the center of an arc or circle.
...
This tool is handy if you have a single profile that you want to sweep over multiple paths, or rails. In this example, there are three paths for the same profile:
Here are the results:
If you used a Compound profile for the profile, you will be able to modify the resulting 3D object by modifying the original profile object, or by moving the base point object. If you used a Compound profile for the path, you will be able to modify the resulting 3D object by modifying the original path object/s.
The sweep path does not have to be 2D. The path in this example was created using 3D Spline by Fit Points.
This is the result:
Local menu option
Rigid Sweep: Keeps cross-sections of the solid parallel to one another along the entire path. See explanation under Profile Objects.

Creates a 3D object by revolving a 2D object about a revolution axis.
By default, the profile will be revolved 360 degrees, but you can change this angle or create a spiral. See Profile Objects.
- If you want to select only a simple (single-object) curve, make sure Use Compound Profile is not selected. If you want to use a compound profile, see Profile Objects.
- If you want to select a line as the axis of revolution, make sure Select Revolve Axis is active.
- Select a 2D object to revolve.
- Select two points of a revolution axis, or, if Select Revolve Axis is active, select the axis line..
The revolved shape is created.

Creates a 3D object by connecting 2D profiles. The profiles lie on different planes, and the planes do not have to be parallel. The profiles are connected using NURBS (Non-Uniform Rational b-Spline) calculations.
The profiles can be closed or open, but they must be consistent - all open or all closed.
- If you want to select only simple (single-object) curves, make sure Use Compound Profile is not selected. If you want to use compound profiles, see Profile Objects.
- Select the profiles, in the desired order. Selection order is important
- Select Finish from the local menu, or double-click on the last profile, to create the loft.

Graphic Along Path
Available in TurboCAD Pro, and Platinum Only_
Places a 2D profile or 3D object along a 2D or 3D path.
- Select the profile or object you want to project, then select a point on the path where you want the projection.
- Click more points where you want profile projections.
If you rotate the model, you can see the profiles in 3D.

Local menu options:
Sets: Specifies a number of copies of the object that will be placed from the insertion point onward. The space between the insertions will be equal to the value in the Distance field.
Distance: Set the distance between the multiple insertions specified by the Sets field.
Delete Original: Deleted the original object.
Flip Original: Flips the inserted objects, creating a mirror of the original.
Set Graphic on Path Start Point: Sets the insertion at the start point of the path.
