I see that you are planning on adding an option for tandem bicycles. Do you have an idea of when that will come out?
I feel bad that I told some people at last years NAHBS show that I hoped to have a tandem version done by this year's NAHBS. Well, it's the eve of NAHBS 2012 and I've been too busy with other tasks to start work on the tandem option. All I'll say for now is that it's definitely moving up in the queue.
Please, bring the tandem option on bikeCAD!
Another "yes please"... *goes back to twiddling thumbs*
I'm another person who is looking forward to this.
I'm going to bump this thread and say I have been playing with the old TandemCAD and the Pro 10.0 version and I can get different numbers out of the 'same' model.
If I select BB drop, HTA, fork, etc to all be the same I get different mitre - mitre lengths for the tubes. Not much, but still a mm or 2...
If you are using the old TandemCAD, then you are modeling a tandem. If you are using version 10 of BikeCAD, then you are modeling a single diamond frame bike. So they are obviously not going to be the same model. However, I trust what you have done is modeled the front end of the tandem and done your best to match up the specs on that with the front end of your single bike. You claim that you have chosen the same BB drop, head angle and fork. If you are seeing a discrepancy in miter lengths, my assumption is that you have still failed to match at least one critical dimension beyond the few dimensions you've already checked. Remember, all the following numbers would also have to match if you want the down tube to be the same on both models: front center, BB shell diameter, lower stack height, fork length and rake, down tube and head tube diameters, extension of head tube below bottom edge of down tube, down tube offset at BB.
