BikeCAD Pro How To Forum

I normally run Pro on my Mac but wondering if it's possible to run on a Chromebook?

I was recently asked to demonstrate how one might document a design in BikeCAD using specs from Retül. This is a common question, so I thought I would post my response here on the forum.

The sample Retül session was for a 51mm Specialized Dolce. Before looking too closely at the Retül dimensions supplied, I figured I would model a Specialized Dolce based on the frame geometry posted on the Specialized website.

Below is the BikeCAD model I developed. As you can see, the BikeCAD dimensions match the specs from the Specialized website which I've pasted alongside.

Hi, im new in this world, you have a great program.

A question, when i load a recent cad file, the program runs too slow. Cant do anything, my computer its too fast, a nvidia graphic and an i7 processor.

Any solutions?

Sorry for my english. Thanks and greetings.

Is there any way to model a tapered head tube in BikeCAD Pro? I can see how to create a "stepped" variable diameter head tube but is not obvious to me how to model a head tube that has a constant taper from the top to bottom? An example of what I am refering is the Paragon Machine Works HT2055.

Thanks!

Is there any way to have an inset top and external bottom headtube similar to the Canecreek ZS series? or the similar King series?

Since I got back from the hospital (got hit again) I can't get my copy of 8.1 to work on my old dell. I have tried to get it to work but it just keeps trying to unzip itself. I have a set of plans that used to work but now no good. I guess that three hundred and fifty bucks I spent might as well have put the money in the street and set it on fire.

Hi Brent,

I'm trying to design a basic step-through frame, but having trouble. In order to angle the top tube down and to intersect the seat tube at a lower point, I have tried increaseing the top tube/seat tube setback (in primary dimenstions), increasing the top tube angle, and then switching to front-center to shorten the head tube, none of which results in a workable design. Can you give me a pointer?

Thanks

Hope all is well Brent.
Quick (basic) question on mitering angles.

I am going to be setting up my new milling machine to start cutting tubes!

Looking at my design it appears there are two angles given...miter angle and interior angle.

Ex:

Top Tube Rear Miter angle: 165.9˚

Top Tube-Seat Tube interior angle: 75.9˚

Whats the difference between the measurements?

To me (based on the visual picture) it seems that I would set up my mill (the vise has a graduated swivel) to the Top Tube-Seat Tube Interior angle.

Hi

BikeCAD 10.51 an 11.0 seems to forget the saddle height. If I open a saved file there is always the default saddleheigt no matter what height it was when i saved it. not a big deal but is it a bug or am i making something wrong?

thanks

I have just started using Bikecad pro and I love it! I have the latest version. My problem is designing a double integrated seat tube and top tube, like on the Budnitz (see pic). I understand that I have to use a workaround and connect the seat tube to the head tube. That works OK but I then want to adjust the curvature and I can't work out how. I see in an older post that you can adjust a field called tire clearance to change the curvature, but I can't find that. Any help gratefully appreciated.
