Re: [PATCH] Option to not render 3D models for footprints

  Thread Previous • Date Previous • • Thread Next
Maybe a better option would be to have footprint variations similar to aliases. Something with a new name, new 3d model path and new description but the same land pattern.
This could be useful not only for having specialized 3d models but also when the manufacturer uses a very strange part naming scheme where it gets hard to define a footprint name well such that it tells the user which parts it exactly fits. (Example is if the part number code has for example a place that is either a,b.e for fp1 but c,d for fp2. right now we would need at least 3 possibly 5 footprints to properly do this.)
The individual visibility stuff could also be useful for usecases that do not fit the one handled by my suggestion. One example would be a battery holder where you have the battery as a separate model. You might be interested in seeiing how it looks without a battery. Maybe even have a model where the battery is in the process of being inserted to see the space required for that task.
Or a shield that covers some other parts. Might be useful to just hide this alone.

Multiple models is an existing feature (for building up parts).  There’s just no individual control over visibility.

Sorry it took so long to get back to this but I've been really busy.
The the capacitor example makes sense although I'm not sure this is a
significant enough feature to warrant a file format change.  I'm not
terribly opposed to this idea either.  I do have a few questions.  Can
multiple models be visible at the same time?  If so, have the STEP and
VRML exporters been tested to work under this case?

Cheers,

Hi Wayne,

No, it would need to be saved in the file.  Think of it as Units for 3D
models: for instance you might have 30mm, 35mm and 40mm tall capacitors
all assigned to the single 20mm diameter 7.5mm pitch footprint.

Cheers,
Jeff.

Jeff,

I haven't looked at Oliver's patch so I'm flying blind here.  My
question is why does this require a board change.  Is this a state we
really need to save in the board file or could it be some 3D viewer
visibility state option saved in a config file?  I would prefer the
latter if possible.  I guess I don't understand the purpose of this.

Cheers,

Wayne

@Wayne, this builds on top of my m_Preview addition so I’m happy to
review it and merge it after Oliver re-bases.  But where do we stand on
PCBNew file format changes for 6.0?  (There are also some hold-overs I
have from 5.1; namely storing defined diff pair dimensions and the
courtyard DRC settings in the files.

This has gone unresolved for a while now - if I put in some effort to
rebase this, is there any likelihood it will be accepted?

This patchset does involve a file format change to the PCB file but it
is backwards compatible and introduces a useful new feature.

    The attached patchset expands on the "Preview" checkbox in the 3D
    model tab in the footprint editor.

    This "Preview" option currently only applies to the preview
    window. However if the user wishes to disable display of a given
    3D model in the PCB renderer they must delete the 3D model from
    the footprint entirely.

    The new patchset does the following:

    1) The state of the m_Preview parameter for each 3D model is
    observed in the various 3D renderers and exporters

    2) The m_Preview parameter is saved to file (both .kicad_mod and
    .kicad_pcb)

    With regard to file saving, if the 3D model is "enabled" (default
    state) then the file is unchanged making this change largely
    backwards compatible. If the 3D model is disabled, then the
    keyword "(disabled)" is added to the file.

    You can now quickly toggle 3D models on/off on an individual basis
    and this is statefully saved between sessions.

    Patch-set is rebased and compiled
    from b445b0fab28f7dd41273801d06d7705215c57c0f
