"Elliptic Arch Window" object for AC10

Anonymous — Wed, 24 May 2023 10:46:16 GMT

Hi to everyone,

I used to make a decorative elliptic arc opening in AC 9 as per attach picture. This object was not part of the AC INT version.
Unfortynately this window object is not working with AC10. I have try copying the 2D and 3D script but in vain ( I am not at all good at GDL).

Can someone please help me to either:
1/. rewrite this GDL object for AC 10
2/. or help me to find another Elliptic Arc Window Opening

Thanks.

Here is the GDL object

oops2,
I downloaded your object and tried it in AC 9 and AC 10.
It works in both versions. This window is old. It appears to
have been made prior to AC 6.5 but after curved walls
were introduced in AC.
When you say "this window object is not working with AC10"
in what way is it not working ?
I can only ask this because, as I said, it works for me.
You might try opening the object via
file->libraries and objects->open object and save it.

Peter Devlin,

Thanks for your reply.
I have just try the object on another computer (at office place with win XP) and as you say it is working.
In fact when I said that it was not working (at home with win XP) for me, the object library would not be loaded by AC10.

I have just saved the object with AC10 and will try it again at home place and will report back.

Thanks again

Hi Peter Devlin,

I have tested it at home and is working after having created a new and reset file (AC default). I just do not know why it was not working before.

But as you stated this a very old object.

If you look at the picture you will see that it is half of an ellipse. There is a library name "W ellipse Arch Opening" in AC10-INT but I cannot configure it to make an arch as in the picture.

Can you please help me to modify the "W ellipse Arch Opening" in AC10-INT. I would like to reduce the minimum height of the Arch to 300 mm.

Thanks

oops2,
If you were satisfied with how the "old" object worked
why not just use it rather than trying to modify "W ellipse Arch Opening" ?
Modifying new doors and windows is not easy as they use several
levels of macro calls and these macros are complex.

OK. Thank you for your help.

I was just thinking that as the one I used is an old object perhaps it would be better to have a more recent one, especially if it is provided in the AC library.

Thanks again.

oops2,
I had a look at the code for "W ellipse Arch Opening" as I have
a copy of the INT library and it does not have macro calls
but it does have hard coded limits on the proportions of
the opening width to the height of the arch.
I did not try to figure out why these limits were imposed
or find out what happens when the limiting code is disabled.
It did not appear that it made a shape in any way superior
to the "old" library part.
However, you may have discovered otherwise.

No. I have try every possible combinations but have not been able to make a true elliptic arch as in the picture.

oops2,
I had another look at "W ellipse Arch Opening" and from
what I can tell the arc is not a true ellipse but is composed
of three circular arcs similar to the way one made an
approximation of an ellipse using a drafting compass.
I am in the process of making an elliptical head opening object
that just cuts a hole with correct shape in a wall.
I am puzzled about why whoever wrote "W ellipse Arch Opening"
did not make an object that was a true ellipse.

Thank you very much.
Please refer to the window library I posted. In AC9 it is possible to show the Ellipse in 2D.
If you would consider this, it will be great.

Maybe it is a wrong translation for a three centered arch, which is part of our German library.

Peter,
Its a matter of long standing tradtion and practicality when it comes to design and construction...Ellipses are approximated for this reason. here's a good link to further describe what I'm saying

http://www.nexusjournal.com/conferences/N2000-Rosin.html

Several years ago I scripted an object to do this in plan when ArchiCAD wasn't able to draw ellipses. As far as i'm concerned ArchiCAD still does not offer the ability to draw a true "approximated" ellipse...If you need one, you still have to manually construct it.

HTH,
Dan K

Any news please.

oops2,
I have completed the object for what it is worth.
It does the same thing that the "old" object does but in a deferent way.
If you want the object tell me your e-mail address and I will send it to you.

I have sent PM you the necessary info.
