Drawing an existing building

[Anonymous]

I am trying to draw up an existing building and need some help. I need to recreate the original lintels and molded decoration on the facade.
I have no idea how to do that.
Could somebody please give me some adivce. I have attached two images that show what I need to achieve (the white lintels).

Hey,

Hit the F1 key. The online documentation for nine includes a whole section on Object Making without GDL. Work through this and you should grasp how to create stuff on the flat, use the 3D window to tilt it in the proper orientation and save it as GDL objects.

I am on the case! Thanks.
Just need to figure out how to tilt in the 3D window. Tried yesterday and failed.

How do you do it? I have tried and cant figure it out.

the purpose:


Can you rotate objects around the X or Y axis? For example if i draw a ornamental lintel with the slab tool in plan view, how do i then rotate it around the X axis so i can use it in elevation?

Make the object in plan then view the elements in 3D changing the orientation to match that of the proposed object ( generally elevation view from the top) While the 3D window is open save (as object),
Easy


Alternatively you can exit the actual script using the ROTx command - Suggest you read the GDL manaual if you want to get invovled in that.

Patricprz,
You seem to have done everything right but are having trouble
with the final step in the 3D window.
AC will make an object from the contents of the 3D window but how
it makes the object is dependant on the view angle settings in the
the 3D window. Specifically, Image->3D projection settings where
you specify whether the view is axonometric or orthographic
(meaning side view or top or bottom view).
In the case of your lintel you have probably drawn it as a slab
in the plan as it would appear in elevation.
If you view your slab in the 3D window with the projection settings
set to dimetric axonometric with camera angle set at 270° you
will see the slab lying on the ground facing up.
To have AC make the object so that it is rotated about the "X" axis +90°
You have to adjust the projection settings so that the view of the
object in the 3D window is the same as how the object should appear
in plan view (top view).

In this case you must do the following in the 3D window's
projection settings.
Set the view to "side view" (face-on gable end view icon) and
drag the camera icon to 90° (top of circle).
Now you are looking at the lintel as it would appear in plan view
(top orthographic view). This tells AC how to rotate the new object
in space the way you want it.
Now save the contents of the 3D window as a GDL object.
HTH,

patricprz,
On the AC 9.0 CD in the folder named Graphisoft Documentation
there is a PDF named Intro to object making.pdf that should interest you.

Read my post preceding yours ...

Djordje,
I have the Mac US version of AC 9 (just got it) and there is
in the Archicad 9 folder a folder named "Graphisoft Documentation"
but the only thing in it are 3 PDFs relating to MSA.
In my previous post I noted that I found a folder in the AC 9 CD
named "Graphisoft Documentation" that had several PDFs including
Intro to object making.pdf.
I did a search on my Mac for the term "object making" with zero results.
Does the pc version of the program install these PDFs somewhere
and the Mac installer does not?

thanks for all the help. but i do think the process should be simplified.
i dont understand why one can not rotate objects around there central axis. it would be a useful feature.
how would you for example place an object level on a ramped surface?

OK to make it simple, you draw a slab.
You select your slab, go to the 3D view menu and choose to see the edge of your slab.Then in the File menu > GDL Object > Save as and once you chose a name, you have a new library part.
Once inserted in your drawing, you will see the edge of the slab as if your slab had turned into a wall.
With the slab tool you can easily draw a lintel, a table, whatever you want.
If you wish to rotate that library part, you have to open it (File menu>GDL objects>Open object), click on the 3d script and add these lines at the top of it :
rotx rotation_x
roty rotation_y
rotz rotation_z
and save.
Next time you will open up the library part you can choose the way you want to rotate the object.
Hope it helped.
