Friends, I have got in a muddle again, and this heat isn't helping. :(

I was in the middle of some new timbering options for short-angle diamond-crossings when I got distracted back into the 3-D exports. Now I can't remember where I had got to or what I had in mind to do next. If I try to get back into that I shall lose track of all the new stuff in the 3-D exports before I've released it.

So later tonight I am going to release version 228a exactly as-is now. If it turns out to contain bugs and non-working bits, I'm very sorry.

You will be able to create crossings down to 1:0.5 but only for the geometry -- the crossing angles and locations. Below 1:1.5 the timbering will be all over the place and you will need to do some timber shoving to create a usable template. Also at very short angles Templot switches from curviform V-crossings to generic to avoid maths exceptions. When I have got back into it I will explain it properly, but for the present there is a lot of explaining to do for the 3-D exports and 3-D printing, and I doubt I can do both at once.

If this reads as if I haven't the faintest idea what's going on in my own head, you will be right.

I've already had one boiled egg today, but I think I need another. :) Then I will get on with preparing the 228a release.

cheers,

Martin.

Well, I for one am looking forward to that release, and with those sorts of crossing angles, timber shoving is pretty much a given anyway!

I’ve actually now taken to writing things down in an A4 blue hardback notebook. I tend to drift backwards and forwards between projects and often have absolutely no idea what my intentions were when I come back to them! At the time, it was “I’ll do that in a minute”, then that minute becomes a year or more before I know it!

Thanks Martin - I've been playing!

Something I've not really noticed before - when using the peg/align tools / make diamond crossing option, that only works if one or both tracks are curved, which is usually the case anyway. I know we can make regular diamonds another way, but would it be possible for that menu option to just not care whether the tracks are curved or straight? It might pre-empt questions when the Sorry, it is not possible to fit a diamond-crossing to these tracks. message pops up, with no explanation as to why! I got there eventually, but others might not.

Cheers,
Paul

Hi Paul,

Thanks for being diplomatic. :)

But you know and I know that's a bug! And quite a serious one. I knew the new code wasn't finished but I just couldn't remember where I had got to, and in this heat I just didn't have the energy to go through it all and test everything again. Sorry about that, I will get it fixed as soon as I can.

I decided to swap the make diamond-crossing at intersection function from the previous geometrical method to use the find intersection search method instead. I knew it would be risky, but it gets rid of all that "is this the right intersection, try the other one" stuff. When it works. :(

While you are in a code testing mood, would you care to see if the make return curve bug is fully fixed? :) see:

https://85a.uk/templot/club/index.php?threads/pegs-not-notching-on-groups.195/post-1763

It should be fixed, it was just one line missing in the code. Thanks.

cheers,

Martin.

Hi Martin

OK, I did wonder if it was a bug :) but I also wondered if that specific menu option should perhaps have read make irregular diamond...

On the other question, this morning @Simon Dunkley has said it's working, but I may have a play when I get home. I'm just having the PC on as little as possible at home at the moment to reduce the number of heat sources in my little flat!

Cheers,
Paul
