BikeCAD Pro How To Forum

This is my first post and after a quick search I couldn't find how this is done. I saw someone's beach cruiser drawing so I'm sure it's possible but I see no options to add a 15 degree curve in the downtube to add long-travel suspension fork clearance (at least where I'm looking). It'd be great to have it spit out the correct miter angles so I don't have to file too much by hand!
Any help would be greatly appreciated!
Thanks,
Whit

Hmmm... not sure how people haven't noticed this, but it would seem the library forks (I'm personally referencing the "Fox-like" 29er forks), use the axle-to-crown (AC) length as the L length, which is incorrect since:

AC^2 = L^2 + R^2 (basic trig...)

So with a rake (R) in the range of 44mm to 51mm, that makes the "virtual" fork in BikeCAD ~3-4mm longer than it should be... which is enough to throw angles out by about 1/8 degree. Or if angles are matched, then linear dimensions then become out of whack. :)

Easy workaround is obviously:

L = (AC^2 - R^2)^0.5

Hi Brent

I have a few issues with BikeCAD Pro that I hope you can help me solve.

1. When working with the same type of frame, but in different sizes from different BCAD files, and going from one size to another by opening "recent BCAD file". Then BikeCAD mixes up the different drawings. So working on a 52 and saving it, then opening up a 56 saving that file and opening up the 52 again, then the 52 will have the headtube lenght from the 56. I guess I'm not supposed to leave BikeCAD Pro every time I want to open a new file, so what is the problem?

Hi Brent

Great product. New BikeCAD Pro user and have a few questions.

If I want to design a curved top tube, how should I understand the curve parameters in Tubing ? I'm trying to get the top tube to bend downwards.
Can the "bend" be curved by defining a radius for the top tube?

Is there anyway to get numbers/distance shown regarding toe overlap? Meaning the distance between foot/pedal and tire/mudguard.

thanks

Christian

Brent,

'When I try to open the exe file in Windows 7 by right clicking I don't have the option to select "Run as administrator" in the drop down menu. Just selecting "Open" doesn't work. What should I do? Thanks for any help.

Does BikeCAD Pro have enhanced features beyond what I see in the free online version that allows you to visualize and design for tire clearance at the bottom bracket, seat stay bridge, and perhaps fork crown?

Thanks,

Hi - I would like to load BikeCAD Pro on both my desktop and on my laptop - do I need to buy the program twice or can I load it on both without having to buy it a second time? Many thanks, David
