Now that I have mastered (not that it is complicated) this useful addition I have to say that it simplifies and speeds up the process a great deal with the added bonus that far fewer partial templates are required for complex formations.  It was particularly useful in producing the 1:4 outside slip.

Thank you and well done Martin.

Hi Martin

Just passing through...

I think I've found a bug on the check rail adjustments(Ctrl-Shift-F9) that only applies to irregular diamonds, and only on DS2.  Basically, if you try to adjust the flared length you get unexpected results - the rail length seems to change but the flared length doesn't.  It also doesn't seem to always remember what you typed!  So, for example, if you set a silly length of 2" (prototype) it shows 4" in the dialogue box, but actually seems to be about the 42" I started with.  The longer I make the flared length, the shorter the rail length gets.  Using the mouse actions, flare length and rail length do exactly the same thing, which is to adjust the rail length.  Setting the flare length to zero does work though.

I've tried this with regular diamonds, straight and curved, and there's no problem there - it just seems to be DS2 on irregular diamonds.

This ability to adjust check rails independently is absolutely brilliant - the number of partial templates reduces massively.  I have a short angle diamond in one plan with a 42" flare on the MS check rail and 12" on the TS check rail - all done in one template now!

Cheers

(Forgot to mention that this is on the latest TDV 4703)

Hi Paul,

Many thanks for finding that. :thumb:

It's actually on both DS1 and DS2 flare length not working properly when the half-diamond is irregular and the V-crossing is curviform.

I will get it fixed.

It's complicated because all 3 adjustments are inter-related to prevent geometrical impossibilities -- the flare length cannot be set less than the end gap obviously. Or conversely the end gap cannot be set more than the flare length. In practice I have limited the flare angle to about 40 degrees to be safe.

p.s. Welcome back. :)

regards,

Martin.

Hi Paul,

Fixed in the next TDV update.

It was deep in the check rail code and took me an hour or two to find. Spot the difference:



Wrong:

case get_flare_type(ccd.end_diff_te.type_diff) of
  1: cuckendox:=cuckendx+j*SIN(k3+k10+k9-k5_te);
else cuckendox:=cuckendx+(j+fw-fw_end-ccd.end_diff_te.gap_diff)*SIN(k3+k10+k9);



Right:

case get_flare_type(ccd.end_diff_te.type_diff) of
  1: cuckendox:=cuckendx+j*SIN(k3+k10+k11-k5_te);
else cuckendox:=cuckendx+(j+fw-fw_end-ccd.end_diff_te.gap_diff)*SIN(k3+k10+k11);



:)

Thanks again for reporting it. :thumb:
 
regards,

Martin.

Hi Martin
Fixed in the next TDV update.Is the same bit of code used in curviform turnouts, as well as irregular diamonds?  :?

I had to look carefully at the code to spot the difference!  It's ages since I did any coding.

p.s. Welcome back. :)Thanks - but I'll be around less often, I think!  I did pop into the forum from time to time to see what's doing.

Cheers

I'm trying to put a scissors crossing into a space that's apparently too small. The problem is getting the check rails in. The check rail adjustments(Ctrl-Shift-F9) makes it much easier to try things.

When there is limited space, is a check rail ever machined on both sides ?

Thanks
Mike Johnson

Yes. See for example this pic on the Scalefour Soc. site:

http://www.scalefour.org/resources/trackdetail/chairs04.html

Another important consideration is that wheels must never contact the top of a check rail. If that is possible, for example at the ends of the K-crossing check rail in a slip, the top of the check rail is machined down to clear. Usually by 1/4". The reason is that as the running rail wears down, the wheels could hit and damage a renewed or replaced full-height check rail. I've never seen that machining modelled, but as 1/4" is only 3 thou in 4mm scale I'm not likely to.

See it I mean. :)

regards,

Martin.

Ahem!

Yeah I can see it, whether you could see it from usual viewing angles and distances is probably less likely, but it's nice to know it's there.

Cheers Phil. :D
