However, in the tubing menu <img src=\"https://www.bikecad.ca/faqFiles/TUBING.png\" width=\"24\" height=\"24\" alt=\"Tubing icon\" title=\"Tubing icon\" class=\"blackborder\" />, the seat tube can be adjusted through the <em>Offset at BB</em> field. Positive values will shift the tube forward. Negative values will shift the tube backward. The same field exists in the down tube section. Here, a positive value shifts the down tube upward. A negative value shifts the down tube downward.</p> <p>The offset dimension is measured parallel to the center line of the tube. This offset dimension can be shown in the Dimensions dialog box by selecting <em>Tubing >> Down tube >> Offset at BB</em>.</p> <p>The chain stay can be offset in a similar fashion, except this input field is found in the <em>Chain stay</em> dialog box <img src=\"https://bikecad.ca/faqFiles/CHAINSTAYS.png\" width=\"26\" height=\"24\" alt=\"Chain stay icon\" title=\"Chain stay icon\" class=\"blackborder\" />. The field is labelled <em>E</em>.</p> <p>When designing unconventional frames where the seat tube may attach a great distance along the down tube or along the chain stays be aware of this toggle icon <a href=\"https://www.bikecad.ca/seattube_mitered_to_downtube\"><img src=\"https://bikecad.ca/faqFiles/stdtMitre1.png\" width=\"33\" height=\"33\" alt=\"ST/DT miter icon\" title=\"ST/DT miter icon\" class=\"blackborder\" /></a>. This icon controls whether the down tube and chain stays are mitered to accommodate the seat tube or if the seat tube is mitered to attach to the down tube or chain stays. The seat tube will only connect to the chain stay if the wishbone check box is also selected in the <em>Chain stay</em> dialog box.</p>","","1","0","1","0","bcurry");
