Well, the licensing will be managed by EW, so it has to be downloaded from there. here there could be a link.

Sketch-Int will be available soon on SketchUp EW, trial also.

This plugin is now Renamed to Sketch-Int
and moved to SketchUp Extension Warehouse.

new user. how do you change units to metric?

Once SketchUp is set to metrics, just enter your metric values in the dialogs, they will replace the default values.

UPDATE
See V8.4 video at beginning of post.

Maintenant version 7

Walls as single volume is the first step, for me. Once all windows and doors are in, I use Fredo Joint PushPull to add inner material faces.

The download is only from the site http://www.formation-sketchup.quebec. It is kinda quick and discreet. Have you checked your folder ?
Update: NOT NEEDED ANYMORE, so removed

Better Doors on Rail (suspended) and Multiple Glass now even spaced.

EXTERIOR DOORS: first set. Includes sidelights & transom.

Wow !! Great improvement. !
It is so nice not to have an uncluttered component browser.
I use groups for my plugins and was hoping for it in yours.
And the animations are still there too. ! Good work.

Ah I see. Purpose is construction docs.
No I do not want to go there. I left that way of producing docs.
Now I do simple walls (ease of design) and the complex things are shown later on details (ease of change)
And if the details impact on the walls, being simple makes them easy to adjust.

How more complex ?
What purpose ?
An example ?

Update 5.1 !!
After Windows on demand,
introducing Doors on demand.
A first set of interior doors. Plain and multiple glass panes.
Each has opened and closed doors on respective layers.
Wood grain respectful !
Ask if you need a particular door. Maybe I can add it.

Well Juju, my video shows a wall made of a simple box. That works fine, using the fill section feature of Styles, SU21018.
Do you mean with wall finish thickness on both side ?

L'extension MCF3D
permet de créer murs et fenêtres et ouvertures à la volée !!
La version 5.1 ajoute les portes (intérieures pour le moment).
Respecte la bonne orientation du grain de bois.
Portes ouvertes et fermées sur calques respectifs.
Disponible sur L'Extension Store de SketchUcation.

Did you find a solution?
One of my trainees is having the same problem on win 7.
Fresh new installation, no other plugins than SU.
Need help.

Updated to v5.02
To let the sun through the openings.
And to make signature stay.

McF3D v5 updated to 5.01
To correct a little 1/4" offset in glass panes.

UPDATE
V5 ! Now create windows on demand. Much, much more flexible. Automatic naming. Wood grain oriented. No need for dynamic components for windows anymore.
Doors will follow later.
English and French are updated. Others will follow.
Works in any units.
