BikeCAD Pro How To

 The  design thatI am currently working on has an 8 inch head tube length. It would make it a lot easier for me if I could shorten it to about 5.4 inches. I don't see a measurement in your frame set up that allows you to change the head tube length. Did I miss something?

 I know I've asked this question before, and I'm sure you told me how to fix it but I've forgotten.

Hey Folks,

It looks like the NDS drop-out is not in the right place when I turn on the Aux View for CS/SS. And when i turn on the tire two appear. The CS are symmetric. Not sure what else I should be looking at.

Thoughts/suggestions?

Having trouble with downloading one of the designs that you have in your library.The problem is that my current version 11.4 doesn't seem to recognize the file that I downloaded. Do I need to update to the current version?

I got a bit of a problem. I had a good design of a 24 x 1.75  pair of wheels on a current little knock around I had designed. Then my computer got sick. Unfortunately I lost that design and I am  subsequently forgotten how to change the tire/wheel size  from my standard 700 C down to that little science wheel. 

 any clues?

Hi all,

I am probably missing something, but I would like to increase dimension F in the seat stays window to achieve a nicer bend profile to the stays.

However, the label appears greyed out and I can't see any means of defining this dimension.

Thanks in advance, and apologies if this has been dicussed somewhere previously.

Hey Folks,

I ran into an interesting issue when mocking up a balance bike. 

1. BB is set to 0/0

2. DT offset is 20mm

3. I'm trying to match the DT/ST offset at the CS.

I realized that when I try to reduce the saddle length from a standard 270mm to 240mm (e.g. Specialized Romin to Power saddle for example), the saddle length adjusts by chopping the rear of the seat. But what if I want it to reduce the length from the front? IS his possible?.  I realized that by only chopping the rear of the sadddle, I cannot get the acutual saddle set-up (rail posiiton on the clamp) that exists on a bike I have measured.

For the purpose of fitting I measure fore/aft and effective body extension from the sweet spot of the saddle (widest point of the saddle).  Is there a set dimesion that rcognizes this protocal and if not how do I create one (other that the right click start a new dimesiont option).   In other word I want a standard dimisention and calcualtes the changes in reach and fore/aft when adjsuting saddle height, stem length, spacers... and so on

I would like to know the height and distance of the rear axle relative to the BB center in a coordinate system where the frame is rotated so that the head tube is perpendicular to the ground.   I think this is JFX and JFY.  Can you confirm?

I apologize if this is basic or has been covered...

Is there a way to save which dimensions one has checked?

I use one set of dimensions for frame design (Effective TT, Actual Chainstay Length, etc), and another set of dimensions for building (HT Bottom X/Y, Horiztonal Chainstay Length, etc.). It would be awesome if I could save which dimensions are checked in those two states, and then flip back and forth between them, without having to find and check/uncheck each individual measurement.

Let me know if this doesn't make sense!

Thanks!
