Hi,
I'm sorry I have not answered early.
Which Kicad version are you running?
Nightly version (now v5.0.0-rc2-dev) has an better 3D manager than
version 4.0.7.
Anyway, all the problems pointed out by Bernd can be solved with
kicad-stepup, a killer application for managing 3D models and footprints.
You need Freecad 0.17. Kicad-stepup comes a a Freecad workench.
Kicad-stepup has many functions, but the basic ones are:
-import in Freecad the kicad footprint
-import the in Freecad the 3D model
-alignment of the 3D model and the footprint along the 3 axis
-export the .step and .wrl models with the right scaling.
This video is old but helps to understand how it works.
Regards,
Pedro.

At first it looks for me like a library error. Means a missmatch
between fotprint anchor and 3D modell anchor and/or a missmatch in the
3D modell scaling.
If the 3D modell or the footprint is not made or altered by you, it
will likely not be your error.

kind person let me know what I did wrong and how this may be
corrected? How can I avoid this to happen in the future?
Look at the footprints, where the error ocurs with the footprint editor.
At the upper button bar, there is a button "footprint properties". By
activating, you will get a window named ""footprint properties". There
are two sliders, and one is named "3D settings". There you can choose a
3D modell ("wrl") and adjust the offset of anchorpoint, scale and
rotation of the model.
If all is correct with the librarys, all values there should be zero.
Most problems occure with the anchorpoint.
The anchorpoint of a THT footprint/3D Modell should be pin 1, and the
"center" of the part for SMD.
Another missmatch mostly occures with the scale, because the measures
for the footprints are at inch/10, and often the masures for models are
in mm. So often a factor of either 2,54 or 0,3937 will help.

Post by 'Dr.-Ing. Dieter Jurzitza' ***@t-online.de [kicad-users]Dear listmembers,
I just finished my first project using kicad and I am really
impressed about it's features.
However, when taking a 3D - look onto my project I found that the
through - hole connectors are off - position, apparently penetrating
the PCB at locations they should not be.
I attached two pictures (hopefully not too big), one from the top
side, one from the solder side of the PCB. I marked the off -
position parts by the help of arrows. The "normal" view including the
Gerber data look totally normal. Is this an user error? Would some
kind person let me know what I did wrong and how this may be
corrected? How can I avoid this to happen in the future?
Thank you very much for your support,
take care
Dieter Jurzitza
