[LDCad] From Studio to LDCad

[Andreas Hinz]

Hi Everyone,

I've been searching for a while to find an answer to my question, but unfortunately without any success. So I would like to try here.

I'm doing my digital builds (technic models) with LDCad and after that I'm generating the concerning building instructions in Studio. In some cases I need to modify one or the other brick by using Studio Part Designer. After doing this I would like to use these bricks (or liftarms or whatever) in LDCad. I now found out, when I go this way and export the modified part to LDCad the "inner" connectivities get lost. That means, there is no part snapping to pinholes or axleholes and so on. Part snapping to studs, axles and pins still work.

Did anyone experience the same issue and might be able to give me some hints how to solve that problem?

Sunny greetings from Bremen

It’s two totally different systems; you’d have to recreate the connectivity for LDCad using its shadow library.

Like NW Perry wrote you need to supply shadow (snapping) information for these new custom parts.

You can do that using LDCad itself by adding LDCad shadow meta lines to the custom part. (enable part editing, see also: https://github.com/RolandMelkert/LDCadSh...IBUTING.md "Enabling part editing" section)

You probably could just copy those lines from the original part's shadow file.


Note: by default those metas are stored in seperate .dat files (shadow library) but you can also just add them to the custom parts themselves.

edit: You could also just use some grid editing Kung-fu when placing these parts
