Section of a 3D model

I'm experimenting with a 3D model developped in AC2000 with solid modeling.
Can someone explain me how I can define a viewport that shows a section of
the model. I mean a viewport on a level aboce the bottom of the model that
shows everything below and nothing behind.

Take a look at the DVIEW command. I think that has what you need. There are
also variables that set the "front" and "back" depths for viewing, but I
can't recall them off hand.

Enjoy,

Use DVIEW - CLIP. Clip from front or back to remove other objects in the
view, or front to cut into the solid. Unfortunately solids show as hollow
shells rather than a filled volume. Use DVIEW CLIP OFF to remove clipping
from the view. Save the view after setting clipping, then you can restore
it in a viewport later for printing.

Thanks,
But even with ^your and Time Skenes explanation, we don't get it fixed.
Does somebody know a step by step explantion about how to make a viewport
that shows a section of a solid model - or a book with a detailled
explanation.

My son developped a 3D model of a house at the academy in Full ACAD2000.
We're trying to make in my LT2000 horizontal section views that shows the
different floorlevels and
vertical sections that shows the contruction .

Or can I mail the model to somebody with time and patience

Ok, let's try this:
1) Let's assume you want to cut through the plan view at a certain
elevation. (It will be similar if you want to cut through an elevation at a
certain depth.)
2) Change to the plan view. Set the UCS to match (ie you can see the X&Y
arrows.
3) Start the _DVIEW command and select some or all of the objects.
4) For the DVIEW option, enter the _CLIP command.
5) Enter the _FRONT option. You can now enter where the "cut" is from the
target via the slider at the top or by a distance. Say your object(s)
is/are 300 units high, to cut at the mid point, enter -150.
6) You may need to use the _HIDE in DVIEW to better see your results. Maybe
not for solids though.
7) To change your viewpoint, use the _CAMERA command in DVIEW. A 35 & 35 is
an isometric view. A 90 & 90 is the plan view (assuming plan view = World
UCS).

That's about as much as I've ever done with it.

Enjoy,
Stef
