Union
You can combine two or more 3D solids, surfaces, or 2D regions into a single, composite 3D solid, surface, or region. You must select the same type of objects to combine.
Command entry: union
Create two or more objects. If the area is closed (unless you use a command or BOUNDARY REGION) commands you can use UNION to merge objects into one.
The procedure for cutting off an object from another is made as follows:
- Open a drawing with 2D or 3D objects and display in a 2D or 3D view.
- Choose Modify, Solid Editing, UNION (or)
- Type UNION at the command prompt Command: UNION Select objects: Pick the objects to Union (Press ENTER) Select solids and regions to union: Pick the other solids (Press ENTER)
Solid Objects Unioned Together |
This command UNION can be used eg: when you draw the walls of the house and they want to merge into one entity.The color layer will determine the color of the merged objects.
NOTE: You cannot use UNION with mesh objects. However, if you select a mesh object, you will be prompted to convert it to a 3D solid or surface.
Subtract
With SUBTRACT, you can create a 3D solid or surface by subtracting one set of existing 3D solids from another, overlapping set. You can do the same with overlapping surfaces or 2D regions.
Command entry: subtract
Select the objects that you want to keep, press Enter, then select the objects that you want to subtract.
Objects in the second selection set are subtracted from objects in the first selection set. A single new 3D solid, surface, or region is created.
The procedure for cutting off an object from another is made as follows:
- Open a drawing with 2D or 3D objects and display in a 2D or 3D view.
- Choose Modify, Solid Editing, Subtract (or)
- Type SUBTRACT at the command prompt Command: SUBTRACT Select objects: Pick the main box (Press ENTER) Select solids and regions to subtract: Pick the other solids (Press ENTER)
Objects subtracted from Box
You can only subtract regions from other regions that are on the same plane. However, you can perform simultaneous SUBTRACT actions by selecting sets of regions on different planes. The program then produces separate subtracted regions on each plane. Regions for which there are no other selected co-planar regions are rejected.
NOTE: You cannot use SUBTRACT with mesh objects. However, if you select a mesh object, you will be prompted to convert it to a 3D solid or surface
Intersect
With INTERSECT, You can create a 3D solid or surface by subtracting the intersect portion of one set of existing 3D solids from another, overlapping set. You can do the same with overlapping surfaces or 2D regions.
Command entry: Intersect
1. Choose Modify, Solid Editing, Intersect
(or)
2. Type INTERSECT at the command prompt.
Command: intersect
Select objects: Pick objects
Intersection of Cylinder and Box |
Interference Checking
Highlights 3D solids that overlap.
1. Open a drawing with 3D objects that overlap and display in 3D view.
2. Choose Modify, 3D Operations, Interference checking
(or)
3. Type INTERFERENCE at the command prompt.
Command: interference
Select first set of objects or [Nested selection/Settings]: Pick solids surrounding rectangle and press ENTER.
Select second set of objects or [Nested selection/Check first set] : Pick rectangle and press ENTER.
The solids that interfere will highlight in red
The following dialog box allows you to change the zoom and display of the drawing to see better the interfering objects.
You can also choose to retain the interference objects by turning the check box off for " Delete interference objects created on close".

- Choose Modify, Solid Editing, Extrude Face NOTE: Must be a solid to extrude the face.
- Choose A face to extrude. If we choose more than one face, hold the SHIFT key to deselect unwanted faces.
- Press ENTER.
- Specify height of extrusion or [path]: 20
- Specify angel of taper for extrusion <0>: 45 (Optional)0>
Select face |
Extruded Face |
Taper Face
- Choose Modify, Solid Editing, Taper face
- Choose a face(s) to taper. If you choose more than one face, hold the SHIFT key to deselect unwanted faces.
- Press ENTER.
- Specify the base point: pick the back left corner.
- Specify another point along the axis of tapering: pick point
- Specify the taper angle: 45
