Details:
Cylinder - Diameter:220; Length:300; Aligned:X-axis.
Cone - End Diameter:140; Length:120; Angle to Cylinder:60 Degrees.
Matching: Cone to cylinder.
Concepts & Techniques:
1. Connecting parts as a bend using the 'Snap Node' tool.
2. Fixing part orientation to an angle with another part.
3. Taper Matching.
4. Listing the details of a design including match settings.

Procedure:
1. Create the cylinder (See: Tutorial: Create a Single Cylinder ).
2. Select 'Create Part'
to begin creating the cone.3. Select the Snap Node Tool
and snap the cursor to the end node of the cylinder at the connection
point with the new cone. The new object should now be rubber banding.4. Select the Angle Snap Tool
and type an angle of 60 into the Relative Angle dialog box. Close the
dialog. The other objects in the view are highlighted green indication a special part selection is required.
Select the first object with the mouse cursor. The 3D cursor movement is now restricted to align with the
nearest 60 degree angle to the center line of the first object. An angle indicator shows how the angle is
implemented. Move the mouse cursor close to the position where the second part is to be dropped. The rubber banding object should actively snap to the required
angle.5. Type the length of the cone into the 'Length' edit box. Move back into the design view. The object length is now also restricted.
6. Select the second point with the mouse. This point is now fixed in space by the angle and length of the new object. The edit part dialog box will open on the new part.
7. Click on the end section indicator (highlighted green - See: Edit Part dialog box ) for the free end of the new part. Type in the free end diameter fo the cone (140). The other end is not important (in fact both ends could have been altered to the free end diameter because the other end will be fixed by matching). Close the Edit Part dialog box. This initiates the matching process.
8. In the Match command dialog select 'Object-1' in the 'To:' field, and select 'Taper' in the section field. Displace can default to 'Turn but is not important. Select the 'Match' button to proceed with the match process. The connected end of the cone should be adjusted to match the cylinder.
9. Select 'Weld All' to prove the bend connection is valid and that it forms a proper bend intersection.
10. To interrogate the match dependency using the report listing: Select the cone in the view (unselect the cylinder). Now select the 'Report|Report Selected to Transcript' command. The transcript window will pop-up with the details of the cone object. The 'Match' section of the listing should show that the cone is matched to 'Object-1' (the cylinder) in a BEND connection with match options as - Displace:Turn and Section:Taper.
