BikeCad Acting Weird

I have a clean install of Mountain Lion on a new Mac and the program is acting real buggy. Wondering if anyone is experience anything similar.

The contents of the program window periodically go completely white. A surefire way of making this happen is by trying to change the BB drop.

I downloaded the version 7.11 and the problem still occurs.

Any thoughts?


youtube video to show problem.
Too much BB drop

Thanks for bringing this to my attention. I'm always striving to make BikeCAD as flexible as possible. Your assistance in discovering geometry changes that cause the program to choke will make BikeCAD more robust in the long run.

The reason things go white in your video is because you've specified a bottom bracket drop of 710mm. This puts the bottom bracket underground. BikeCAD doesn't necessarily have a problem modeling a bike with such a low bottom bracket. The difficulty comes when you consider that your wheel radius is 337mm and your chain stay length is 405mm, there is physically no way that a 405mm chain stay could possibly bridge the distance between the rear axle and the bottom bracket under these circumstances.

I'm sure that you had simply intended to type in 71mm (or maybe 80mm?) Had you done that, everything would have been fine. However, on a somewhat related note, if you leave the chain stay length constant, as you increase the BB drop, the rear wheel gap will get smaller. If you wish to retain the same rear wheel gap as you change the BB drop, change the chain stay length menu to rear wheel gap as described at: bikecad.ca/rear_wheel_gap_chainstay_length.

I would like to encourage all customers that purchased BikeCAD Pro from the old site to register for an account on the new BikeCAD.ca site. Once you've done this, please let me know so that I can change your account status to BikeCAD Pro customer and grant you access to the latest version of BikeCAD Pro. I have just done this for you. You can now download the latest version of BikeCAD Pro from within your account as described at: bikecad.ca/downloading_bikecadpro.

Malware in BikeCad?

I really hope this isn't true. I have had malware problems in the past and it's non fun. There is a current discussion on the bikeforums.net website about possible malware in bikecad. Some poster is claiming that he was infected by malware when he installed Bikecad. The post is in the framebuilders forum on that website. See here...

Perfectly safe

Just to clarify, the original poster of that thread was not infected by malware due to using BikeCAD, but only claimed to have seen a warning. He later retracted this claim.

Rest assured, there is no truth to this whatsoever.
