Center a window on a wall (or other element)

[Gus]

I swear that in plan I used to be able to select a window, grab it's central node then hover over another element in the design and get a "tick mark" representing the middle of that wall or slab that I could use to align the window to the center of that element. Am I dreaming that division "tick marks" used to show up when hovering while a window was selected and being dragged?

Yes is supposed to be there, but I had problems with this before.
Check this, this might help.

This is possible to do.
What you need to know is when you start dragging a Door/Window in a Wall, the angle of the drag vector will be locked to the direction of its host Wall. (If you open the Coordinates Box you will see the Angle field locked.) When this happens you will be able to find the middle point of only that edge of the Wall along which you drag the Door/Window.

So all you have to do is unlock the angle by pressing ALT+A on the keyboard. Then the cursor will be free to find any middle point of any Wall and the found point will be projected to the Wall of the Window to calculate the drag distance along the Wall.

There is another method I can think of which uses the new Snap Guides of ARCHICAD 19.
1. Place a Snap Reference Line along the edge of the host Wall of the Door/Window.
2. Place a Snap Reference Point at the point you want to use as a reference when dragging the Door/Window in the Wall.
3. Select the Door/Window and start dragging it in the Wall. Snap Guides will be offered based on the Snap Reference Line and Snap Reference Point you marked. You will be able to find the Snap Guide that originates from the Snap Reference Point on the other element and is perpendicular to the Snap Reference on the Wall edge. Their intersection point will be the point where you want to drag the Door/Window within the Wall (the marked Snap Reference Point projected onto the Wall edge).

Or just hover over the wall before you start dragging the window. Then the race is on to move the window before the snap point disappears

Unless you turn off the 'Autohide special snap points' in the 'On screen options" of your Work Environment.

It means the special snaps will stay on the screen until you (CTRL+ALT+SHIFT+R) or Archicad forces a rebuild and regenerate (i.e. when changing views) or you change the input method for the snap guides (off, between intersection, entire length).

In ARCHICAD 19 and later this is now controlled by the Autohide Snap Points checkbox in the Input Constraints and Guides page of the Work Environment Dialog. With the new Guide Line and Snap Guide related improvements in AC19 this checkbox got renamed and moved to another page of the Dialog:

Hi, I know you are trying to get the center snap point, but here is a technique I use to center things in AC, I hope this can help you.

This has been my method for 10+ years, until I just learned about ALT + A from Laszlo up there

I did figure out how to set the 'time-out' for the snap point a few years ago though... Then again, it promotes fast drafting
