4599a tap does not snap to 4740 dish 2x2 inverted at the top, does work at the bottom?

   

I was trying to achieve the one with the red arrows to create a lamp :-)

Any pin using a 10ldu male cylinder meta should snap to it, if its counter part has 10ldu female ones.

Not sure how many parts have the appropriate meta information in the current shadow though.

Do partial cylinders also count? My motor has only 2x 1-8cylo in the front...

And the boatside pegs are too short, thats why I defined the connectivity (is that ok?)

LDCad uses pattern matching for its snapping like keys and keyholes.

So it should snap, or slide depending on meta options.

Which part is this?

t1210 (https://library.ldraw.org/tracker/31095)

connects to the floating boat hulls, but except for the weighed keel with peg these are too short to completely fit.

And its too rigid to snap, they get slid on.

Not sure how this works in real-life, but it might be better/easier to use a generic shape meta instead.

For example:
PHP Code:
<?php 

0 !LDCAD SNAP_GEN [group=mabuchi] [gender=F] [bounding=box 5 5 30] [pos=0 -37 30]

And a "gender=M" counter part on the matching boat parts.

ah thanks, the motor connector works like a very long clip on a ship-sided bar, too rigid to clip but possible to slide in from the back.

Motor connector starts at 0 -37 0 and ends at 0 -37 60.

Do these connectors snap center-center or start-start?

The generic box example will snap centre to centre forcing a matching orientation.

Sounds like this needs a clip meta with forced orientation. This is not an option (yet Smile )

I might add a 'U' variant to the CYL shape kind in 1.7 Beta 1 as it is relatively easy to implement.

But for now you can fake it by using squire f/m CYL metas which will allow it to slide, but it would allow this in 4 different orientations (like axles).

RE: Part Snapping missing/errors - Rene Rechthaler - 2023-04-22

What is the difference between a pin type and a stud type connection (when viewed in connection specs)?

This is more like a completely fixed connection like the rail connectors...

The only difference is their pattern (pin has ldu 8, 6, 6.25 and stud is just 6)

The reason pins don't snap to, eg, anti-studs is because there is no room for the pin to 'click' (the 6.25 can compress to 6 as indicated by 'L'  but must be 6.25 at rest).

RE: Part Snapping missing/errors - Roland Melkert - 2023-04-30

I wanted to add support for using the github (green button) 'code' zip as-is, only to discover a minor bug is the only thing preventing it working in the older versions.

The bug concerns how LDCad decides if a compressed library is a shadow library.

Current versions only test for the .csl extension, if it has something else it will (due to the bug) fallback to using the filename as a folder which will fail.

The issue has been fixed in 1.7 Beta 1.

But if you want to use the latest shadow as found in github with 1.6 or 1.7 alpha, you must rename LDCadShadowLibrary-main.zip to LDCadShadowLibrary-main.csl. before using it in LDCad.

Most of the time, the telescope jumps to connect its tube to plate stud. Moving the plate instead doesn't help. It works much better with a regular plate 1x1 (3024)!

Finally got to the bottom of this issue (message #109)

It is caused by how 'best fits' are determined when there are multiple candidates.

The current engine can not be (easily) fixed for this as it introduces a chicken and egg problem.

So it will have to wait for the 2.0 rewrite (if ever Angry )

Instead I changed the 1x1 plate to prevent the issue entirely.
