BikeCAD Pro can export templates for coping the mitres at the ends of the down tube, seat tube, top tube chain stays and seat stays. Just choose:
File >> Export miter template (PDF). When the Save dialog box appears, enter the appropriate wall thickness for each tube in the column on the right hand side.

BikeCAD Pro will export two PDF files with templates that can be wrapped around the ends of the tubes as shown above. The first file will be called Your File Name_1.pdf and it will display templates for the front and rear of the top tube, the bottom of the seat tube and the top of the seat stay or wishbone. Click here for a sample. The second file will be called Your File Name_2.pdf and it will display templates for the front and back of the down tube and the chain stays. Click here for a sample.

Be aware that the chain stay template will only be accurate for round cross section chainstays.

Each template is identified by the label at the top. The template on the right for example is for the end of the down tube which joins with the head tube.

The horizontal lines identify which part of the template aligns with the top of the tube and which part of the templates aligns with the bottom of the tube. Be careful. The width of the template must match perfectly with the circumference of the tube. If the template does not match, check that the PDF file was not scaled in some way when sent to the printer. Click here for a sample print dialog box.

Along the right hand side, there are two curves which define the profile of the mitre. One curve relates to the outer diameter of the tube and one curve relates to the inner diameter of the tube. As a rule, you will want to follow the curve which removes the most material. However, if you are able to taper your cut across the wall thickness, then you may be able to follow both. This would either require great skill or simply a different approach to cutting the miter. A different approach would involve the use of a hole cut saw either mounted to a mill or a tube notching jig. When milling the miters with a hole cut saw, use BikeCAD Pro's handy display of miter angles shown here.

Note that the template for the rear end of the down tube will usually include an extra profile describing the intersection of the seat tube. The image on the left shows how this profile should be interpreted. Material to be removed is shown in pink. The left and right hand sides of the tube are marked out by the horizontal lines.

BikeCAD can model seat tubes and down tubes with centerlines that are offset from the center of the BB. This option is available by choosing Aero or offset in the Tubing section. Aero and Offset are lumped together in the same option because when viewed from the side, they essentially look the same. However, it should be noted that although these tubes look the same from the side, the miter template required for an aero cross-section tube would be different than the miter template for a circular cross-section tube with its centerline offset from the BB. The miter template generated by BikeCAD Pro only applies to circular cross section tubes.
