Insert background picture to LDCad - Johann Eisner - 2026-01-16
I just added an image as a submodel using “Session,” “Add new...”, "data", in the hope that I could use the image as a reference for a new model as background.
Just like (here comes the bad S word) it is possible in Stud.io.
The image appears in a new submodel, but cannot be inserted into the main model or any other submodel.
No parts can be added to the submodel containing the image either.
Does anyone know what this function is for, or is it still in development?

It's for embedding textures into the mpd itself:

If you want to use the image elsewhere in the mpd you will need to create a (also embedded) part containing at least a single textured quad referring to it.
Native background images is something I have looked into multiple times but I couldn't make up my mind on how to implement it.
So in short it's still a planned feature

We sincerely hope this feature can be added as soon as possible, and a lock (Freeze) similar to that in Studio could also be included. (I have always found IO less user-friendly than LDCAD.)

I'm still not sure on how to do the background images, but I will revisit the feature for Beta 3.
Not sure what you mean with 'locking'.

It means frozen or locked, and cannot be selected.

Similar to the freeze layer and freeze object functions in 3ds Max.

Ok, I understand. Could be handy indeed. I'll look into it but I will only consider adding it this late in the beta stage if it can be done easily (maybe as a variant of the hide feature).
