Partsnapping difficult sometimes

[Jaco van der Molen]

Hi all,

Currently I am working on a model that features parts like 95228 minifig bottle and 64644 minifig telescope.
I am frustrated by the fact that snapping seems to mainly attract to the top stud instead of the bottom one.
It is extremely difficult to snap the bottom (anti)stud of the bottle of telescope to a stud of a ie. a plate.
LDCad seems to react primarily to the top stud? Especially when there a lot of studs to choose from.
Alas placing this part on top of another part with a stud is very hard.

If you know what I mean and experience this too, is there something you can do about that?

For now I don't even try putting it on and live with it to snap it to the bottom of the model and just move it up ;-)

The same goes for the 1x1 round plate with/without hole 85861 and 6141. Very hard to snap.
Or is it me?

Thanks for reading and for answering or tips.

Jaco

This is a known problem of the 1.x snapping engine. I tried to improve it in 1.7 awhile back but the problem is fairly complicated to fully solve using the current approach.

In the end I decided to adjust the snap of the part causing the issue info instead.

I think it was 64644 combined with a 1x1 plate back then.

I will look into it again.

ps: It wasn't 64644 as its shadow doesn't have the change I mentioned, I will try to find the part in question (Philo do you remember?)
pss: I helps if you rotate the camera so you look directly at the target part.

I do remember the problem but not the solution  I just tried again with the telescope, I found it a bit tricky, but not that much. As for 95228, it doesn't seem to have bottom connectivity at all!

I can't find it ether.

Added a workaround to the repo for the above two parts though.

Studio has a nice snapping function, but sometimes that one is broken, too.
(no connection data, wrong type or position...)
For these cases, I try to move another, unbroken part into that and move them together. Would that also work here?

Yes, but the main solution is to use grid editing to put the part at its final location.

In LDcad the snapping feature was never intended to be the main building tool.

I know that that was the intention, and if you read the tutorial it emphasizes learning the grid method first.

Unfortunately (?) I think the system just works too well now. The temptation to use it as the primary method is just too strong.

The bottle has connectivity since 2015 ;-)

Sorry, I don't like grid editing ;-)
I am so used to snapping.

Tnx!
It seems to get more difficult if many studs are visible and I guess the more the snap engine can choose from, the more difficult it gets.
For now just putting it under a brick and moving it upwards using arrow keys or edit pin, I'm fine.
It would be nice though if snapping would even work more smooth that it already does.

Gotcha. Snapping is in 95228 instead of s01 so 95228p01 that I used to test is missing it...

I moved it to s01 on github.
