From latest tests, adding a vertex colors layers on "hole" does fix issue on parent, the same goes for uvs (at least 1st layer, not checked further with 2nd one).

See T58472 as reference.

It also breaks uv channels > 0,
Add 2 uvs chanels, 2nd one is black with modifier enabled.

Will check twice the mesh generation code - to ensure there is no dups as i do join() meshes together before bisect().
But as far as i can tell, exact same code was (is) working without any trouble under 2.79c and 2.79 lastest buildbot

The bug_to_curve.blend file is a result of bisect done through same code as seen in video, but under 2.8

In edit mode if i recall correctly

# plane co: coord of one point in bisect plane
# plane no: vector of bisect plane normal
bpy.ops.mesh.bisect(
                        'INVOKE_DEFAULT',
                        plane_co=plane_co,
                        plane_no=plane_no,
                        use_fill=True,
                        clear_inner=True,
                        clear_outer=True)

Same geometry is failing on both 2.79c and 2.8 (using crtl+c and paste to move between apps)

Not a bug here,
Archipack addon require additional steps to complete setup.
Enable archipack addon, setup a material library path and press "Render presets thumbs" in Preferences -> Add-ons > Add Mesh: Archipack -> setup actions.

Could you at least provide a description of your issue ?

Ok,
removing faces does fix the issue, but it's a regression from 2.79

Both samples does work in 2.79 but not in 2.8
Basically i do slice geometry using

Will try to find the right way to auto disable on scene switch.
In the meantime, Right click or press ESC to disable manipulators.

This is not a bug, but a restriction from BF to not include thumbnails into source.
A setup step is required to render thumbs,
user prefs -> add-ons -> archipack -> Setup actions -> render thumbs.

Might be lack of vertex/edges/faces select state of solidify output ?
Following code was working under 2.79:
(input geometry is a plane in edit mode)

import bmesh

scene.ray_cast crash in addons running into 3d view too, (since ~1 week - at least 2018-11-14 was ok)
Since the addon is huge (archipack),
i do try into console to make report as simple as possible, so you probably spotted another issue ?

This is not a bug,
In order to generate thumbs, there are some additional steps to setup the addon under addon preferences -> archipack.

Any reason for lowercase units enumerator items in python ?

Was a 403, guess a miss-configuration in my ssh keys.
Solved now, thanks

Not directly related, but anyway .. ref [1]

Still having issues with custom properties and python api defined rounding values in ui while not editing, eg: 9.74303m -> 9.7m
could .precision property or .step property be used as rounding basis for display ?

Checked again with factory startup file.

Same issue with other manipulators.
Maybe a threshold for minimal change required before we actually update the real value could fix it.
At least it is a solution on python side but require a get_cb and set_cb to be handled properly.

Using a bar for shortcuts is definitely not way to go.

Ok, will proceed soon

Missing proper xml import
Never checked category stuff, i only made some cosmetic changes during 2.79 release process related to user defined library path and fixed temporary scripts path to writable folder.
Will probably require more in depth investigations of overall code, might take a look next week.

Not found path message is related to "user defined path" to library not set in addon preferences. It is only info and can't be the source of any error.

Update:
simplify math behind, bugfix for vertices lying on plane, pep8.
Note: unlike bissect tool this one is able to provide section as edges only, and dosen't cut the source mesh.

Another easy to repro failing case (2.79):

Hi,
+1 for .rst documentation.

Hi George,
Select your wall before autoboolean.
Also note that autoboolean is designed to work on closed wall mesh, and may produce unexpected result on open surfaces, as regular boolean do.

Commited fix rBA4bac8438df99 for critical issue T53706

commit fix into master

Bump on this as it also fix common issues like:

For some obscure reason i'm unable to add another diff (support for Gradians angle types)
So i do add the diff here.
Original dxf file from ADSK Civil 3D 2009

Replace try except by explicit check for polyline type.

Only polyline has a writeable .is_closed, other rely on .flags
so if there is a way to know an entity is a polyline, i think we should avoid try except.

To make things clear:

.is_closed is not always a property !
in dxfgrabber->dxfentities->polylines (line 353) it is not so is_closed will at least work with it.

Added comments on why try is needed.

Re-submitted as diff #D2933
as bzztploink suggested on IRC, sorry fro trouble.

Thumbs pics where not allowed in disto to reduce overall size.
So you'll have to generate them using "Render preset thumbs" in T ->Tools -> Archipack Tools panel (may take 2-5 mins depending on your computer)
