BikeCAD Pro How To Forum

Hi all,

I would like the chainstays to be as low as possible on my frames meaning that I want the lower part of the chainstay to come out flush with the bottom of my bb. I had a look in the chain stay section but I'm not quite sure how to work it out, i realise i can fill in a negative value for E and this will lower it, but I am not sure what E stands for. mm under or above center bb?

thanks, mick

Hi everybody,

I have troubles setting the hydra with the "Bike Machinery X" and "Bike Machinery Y" values provided by BikeCad.

I am building a frame for myself, to get to know the hydra. BikeCAD gives me a X value of 526 and a Y value of 276 for the head tube- bottom distance.

There seems to be a calculation step to use to be able to use these values to adjust the jig, but i do not get it.

The jig is third hand and I have no manual to refer to.

Hey Brent,

Is there a way to show seatstay length in standard view (not auxilary). I can do it manually of course but would really like it to be a driven dimension for my dimension templates.

Thanks!

Hi Brent,

I like BikeCAD but I could imagine some additional functions.

Is it possible to expand the box with any round corners?

I draw with the box mounting parts like Suspension Seatpost or Speedlifter.

Some modern Rear Carriers and Lowriders would be nice, too.

You find Dimension drawing on www.tubus.com.

Two things I'm having trouble modelling perfectly:

- Is there a way to model eccentric BBs? I can get the shell diameter correct, but can't work out how to get the BB axle ofset from the centre of the shell.

- I'm designing a frame where the seatstays and top tube will be in line, and want the seatstays to terminate on the side of the top tube, but the design goes wonky as the angle between seatstay and top tube approaches zero - I guess because it's still trying to terminate the tubes under the TT.

Hi All,

Just downloaded BikeCad 12.0 to my Ubuntu 14.04 machine... It will not recognize the files, and seems to require me to change the permissions because it hasn't come from the Uduntu Software Centre.

This all seems ok... Except I'm a complete moron when it comes to computers! Can anybody help me with the step-by-step in Terminal to make this happen?

Thanks,

Hi,

If you curve the stays the T value becomes uneditable and the VR value has no effect. Is that an issue? How could I address that configuration?

Thanks.

I'm not able to Hide or delete a linear dimension line that I created. When I right clicked and selected "Hide" the dimension value was deleted but the line remains. I can not select it to delete. I've attached a screen shot with an on screen note to make the line easy to locate. As the image shows the drawing is for a tandem I drew the line to measure the effective seat tube angle but then discovered this is already included in the included dimensions.

Brent,

I have an existing frame that I'm putting into BikeCad Pro. I have all key measurements, but the head tube height appears to be a dependent measurement. When I adjust the measurement from the center of the down tube intersection with the head tube to the bottom of the head tube, the head tube height doesn't change, rather the down tube slope changes. Therefore, I can't input the correct and measured height of the head tube. Your guidance is much appreciated. If you like, I can email you the file that I'm currently working with.

Best,

TRL

Newbie question.

I am using to reach & stack values to control the dimensions.

But if I want to have a horizontal T.T. it changes the H.T. length.

What am I getting wrong ?
