Hi Brent,

If there is a better way to report these please let me know. I think I found another bug in 24.0 on Linux.

Uncheck "Scroll down to zoom".
Close BikeCAD.
Restart BikeCAD.
Observe that ""Scroll down to zoom" has been checked to on again.

Hi Brent.  I know it's trivial, but is there a way to get a double-bend stay auxiliary view to display taper from the dropout?  I can only get it to display in the middle section of the tube.  

Thanks a lot, Ben

Hi Brent,

I think I found a bug, here's how to reproduce it.

Draw a rectangle around the frame:

Overlay an image (in this example I used apples, but I first noticed this issue with a custom image):

Hi,
 

I'm experiencing an error when trying out the AI tool to compare frame stifnesses.

 

I've tried it on mutiple frames I've created, and also tried it on the frame that loads on initial start up.

BikeCAD 23.3

 

Thanks,

Chris

Slow scroll speed

Scroll speed in the settings menu is extremely low. What gives me a full page say in a browser scrolls only a single line in Swing. Is there a config parameter I can set to speed up scrolling? Also, is there a setting that makes bike cad remember the previous window size of the Customize dialog?

I'm on Linux Mint 22.3.

Water bottle size and location is not saving in 23.2

Bottle location and size reverts to a default dimension of 200mm and a  small bottle size.

Happens when I open an old file.  In 23.2 it defaults back to 200mm/small bottle if saved and reopened after correcting the bottle location/size.

Thanks,

Ralph

Strange Blue Line

Hi there.  The file for my most recent frame has this strange blue line on it.  I can't figure out how to get rid of it.  It follows my cursor around.  It seems to fixed on the right point.  The left point seems to reset to the center of the BB sometimes.  I've tried clearing dimensions, turning everything on/off.  I'm stumped.

How to connect Seatstays to Toptube sides

BikeCAD Pro How To Forum

Hello guys, how are you doing?

Today i want to ask how to connect the seatstays to the top tube sides, just so both get attached in a similar way to the commencal meta ht v2 (https://www.commencal.com/us/en/commencal-meta-ht-am-ohlins-ash-grey/22METAHTAMOH.html?lang=en_US).

I tried to mount the seat stays to the top tube using the seat stays popup, but look like they only get attached to the downside of the toptube, instead of the sides (drive and non-drive).

Thanks in advance guys!
