Hi,

Released archipack 1.3.8-rc1.

Download lastest
Focusing on stability issues, this is an important update.

What’s new ?

  • Improved stability

  • Slab from wall auto-adjust offset to fit wall outside

  • Floor from wall advanced auto-detection of childs walls / slab cuts / doors / windows

  • Moldings with advanced tool moldings from wall

  • Floor support for rotation of patterns

  • Wall to curve (inside, outside, both, 2d symbol with openings, floors boundarys)

  • Stair to curve (2d symbol, hole as curve for slab/floors cutters)

  • Slab, Floor, Roof and Wall: add proper delete tool

  • Slab, Floor, Fence, Wall and Cutters from curve: add support for scaled curve

  • Autoboolean now use intersection based wall holes ownership detection (wall2 only)

  • Reference point shape flat arrows to ease snapping

  • Bugfix: kitchen cabinets dosent allow hole on 1st cab

  • Bugfix: pygeos relate operation not working as expected (contains / touches / intersects… relationship)

  • Bugfix: wall childs detection on open walls leading to wrong relocation

  • Bugfix: dynamic material enumerator not properly holding reference

  • Bugfix: wall relocate childs fails on Split and Remove segment

  • Bugfix: 2d to 3d create wall not always working as expected (view manager clipping error)

  • Single operator to manipulate: bpy.ops.archipack.manipulate()

  • Remove support for depricated boolean carve mode

  • Improve presets parameters filtering on save

  • Loading preset modify all selected objects

  • Better icons and context check for tools (create objects from wall)

  • Reorder create panel so it match typical workflow

  • Fence from curve use curve resolution at create time

  • 2d

    • Section and Camera section objects
    • Multi-dimensions object bound to “measurable points” selectable right on screen
    • Layout object to precisely define “paper space” for export
    • symbol for windows
    • symbol for doors
    • symbol for walls including support for childs walls
    • symbol for stairs
    • Basic dimension object
    • 2d svg exporter

Hi,
You are facing with a known packaging issue with ubuntu, not shipping numpy.
see this post in issue tracker for a solution.

426

i think saving the file solve the problem. at least or me.

427

This is really great, just wonder if it could be the basis for some less sophisticated programming based on already defined arch.objects.
I mean one would not have to necessary learn all the python by combine and manipulate these objects/entities and build some custom/more complicated structures ??

428

Hi,
Archipack is build on top of an api, where all objects share most of the code see Extending archipack in documentation.
You also will find archipack_toolkit.py in the github repo (an archipack’s enabled box) as starting point to implement whatever you need.
This api is ment to hide most of complex parts and let programmers focus on mesh generation.
Archipack is not limited to mesh generation, you also are able to make parametric curve using the api (see dimensions as sample)

I’m working on “archipack_custom” object allowing user to define any simple mesh as “parametric” using vertex groups to define parts the code should handle (top, bottom, left…) so one could make user defined windows and so on, and benefit from manipulators, autoboolean system and so on. (probably will part of 1.3.9)
Implements the same concept as “Assembly” of Fluid designer - but without any driver / hooks.

Custom holes and walls mesh are allready allowed, but require properly closed meshes to work as expected.

429

,
Exactly thats what I meant. Really appreciate your effort, I am not a programmer but still want to try your ‘API’ to try these blocks.
Only one thing is still unclear to me, although rather inherited from Blender itself than your work: Coordinates System. World/Global and Object/Local. Iam used to Acad approach, now try Archipack 1.3.8 and eg. cant get idea behind stting properly section surface/plan but that is minor thing actually. keep your fantastic work, expect support whatever it could be. ))

And one more thing: would you recommend some links for learning python, as per your experience?

430

I’m pretty new to python, coding with this language only the last 2 years.
I started by looking at addons folder, trying to make minors changes here and there.

World coordinates are absolute coordinates of objects.
Local/object are coordinates of parts of an object from it’s pivot.

In the next weeks i’ll try to focus on documentation for 2d parts, in the meantime you could find some rougth samples videos done in development phase.
see Archipack in youtube
Some samples show methods of earlyer versions eg first archipack preview is now completely outdated - use draw tools instead.

Hi,

I install numpy but I only have error activating archipack when running blender PPa on Xubuntu 16.04.4

Successfully installed numpy-1.14.1

NOTE: I don’t have error activating archipack when running blender (official).

What the difference between: Unofficial 1.3.8-rc2 and 1.3.8-rc1 ?

432

Hi,
Archipack 1.2.8 “official” dosen’t use numpy.

The ppa is badly broken, not shipping required python modules found in official blender’s packages.
Also look like you should update pip itself,
setup python3-pip package
then use pip3.

Please do report this error to the package manager as it is not an issue realated to archipack.

RC2 contains bugfix found in RC1.

433

I installed 1.38 but nothing new appeared; also I saw no way to remove the 1.2.8 install so I have 2 Archipacks installed. But the only new stuff which shows from one of them is “Wall” mesh under the Mesh tab.

PS. I installed everything (the old and the new addon) under separate Archipack tab. Can this make a difference?

434

Hi Handel,
You must disable 1.2.8 (don’t worry, 1.3.8 only extend 1.2.8).
By default 1.3.8 use “Archipack” tab

435

Done. 1.2.8 remained (there is no remove option) but if I try to activate it again Blender reports an error.
The new stuff appeared;I guess the mat library pack is the recent one.

436

Done. 1.2.8 remained (there is no remove option) but if I try to activate it again Blender reports an error.
The new stuff appeared;I guess the mat library pack is the recent one.

Edit: I downlaod it from here: https://github.com/s-leger/archipack/wiki/Materials

437

Yep, i try to keep materials library in synch with current version.
1.2.8 can’t be removed, only disabled.

Blender must report error when you try to activate both.

As reference for upgrade from 1.2.8 to lastest:
Disable 1.2.8, save settings, restart blender so if there is any error on unregister it wont affect setup.
Then enable 1.3.8, set material library and save settings.

438

This happened 2 times - working with walls make the Blender just to close. Don’t remember what I did the 1st time but the second time it happened when I tried delete a floor by pressing a Delete button.

Also is it possible to write dumb-proof how exactly to make holes? I watched a lot of Utube tutorials and still never succeeded to make a hole either in a door or in an window. The tutorial I saw putting a door or an window at the same time makes a hole; but I never succeeded to do this. Is this because in the tutorial the windows/doors are put just upon a single wall and I am making the whole room 1st? Also I tried to put a floor on a room 8x6 m; but the floor becomes 4x4 m and rotated at 180 degrees from the room (create floor from slab woks ok). Of course I can edit the size of the floor plane and rotate it to fit the room but this kills the idea of making a floor through a add-on.

Edit: I understood how to put a door/window with a whole - just have to use the option “Draw”. But what is the purpose of the left door.window option then?

439

Hi thank you for your feedback !

In order to make auto-flooring to work :

Make outside wall for your building (closed one),
then add other walls to separate inside spaces.
Add doors and windows.
Then select outside wall and use floor from wall, the tool detect closed spaces and openings and create as many floors as needed.

Same for moldings / roofs.

Note that walls have “side” if moldings are not on the right side, check “flip” on outside wall.
Side also have impact on direction of windows when using “draw tool”.

Will probably remove regular tools for windows / doors, as they always belong to a wall.

Allready put a great amount of energy on documentation part, but archipack still envolve too fast.
Modifications driven by user feedback often depricate available documentation.
So focus on main features on tube videos and once features are frozen will put more energy on it.

Also trying to narrow down every crash issues, wasen’t able to repro crash with delete button on floor.
If you find a reliable way to crash blender using archipack, please do send the file !

Thanks.
Look like I am starting to grasp the concept - the left column of buttons (wall, door, etc) are the “regular” tools, right? The jut create the corresponding item at the 3D cursor. It is misleading indeed for a new users - especially because the “draw” tool I understood as if I have to draw rough outline of the needed item.
As for making a “floor from wall” - in Object mode I selected the closed walls and when pressed the Floor from wall button look where I get the “floor” :

Edit: It is the same when I first create “Slab from wall” and then try to add “floor from wall”. The “Slab” is ok, but the floor is again only under the walls.
