[Equest-users] Modifying Geometry

[Peter Hillermann]

To All:

 

Do not import from REVIT. I use REVIT, ECOTECT, 3DMax and many other
products. If you want to create just geometry objects without building them
in eQuest use ECOTECT or a DXF file from AutoCAD created in 3D. eQuest,
Ecotect and AutoCAD understand and interpolate planar geometry which means
when you create a cylinder you are in fact creating planes that segment a
circle.

 

Short Lesson.

 

2 ways to create surfaces are either by planar geometry or using nurbs.
Nurbs are algorithims that are complex and it is what you see animators use
to create faces, people etc. buildings are best created using planar
geometries because it simplifies the models. With detail mode in eQuest you
can create these planar surfaces on a grid however it becomes very
complicated on larger projects because you have to keep track of your walls,
roofs and ceiling coordinates from your 0,0,0 origin. This is why using the
wizard with the AutoCAD underlay is so effective.

 

This is also why objects tessellate when you create compound curves. In
other words doing a Frank Gehry project in eQuest would be quite
challenging. At this point you would probably need to move to a program like
IES or do the calculations by hand.

 

Back to eQuest.

 

Go to building shell tab. Scroll down to polygons folder. Right click and
select create new polygon. Fill out all the coordinate information.

 

Scroll up to where you floor is identified. This is where you need to decide
which space the geometry will belong to. Each space is created by the
AutoCAD layout which you can get to from 2D geometry right clicking on the
screen and selecting switch to polygon view. In polygon view you can create
your different space shapes. These spaces are then where you attach your
polygon too.

 

These spaces you can use to create HVAC zones with.

 

Hope this was not too complicated or long winded. I still think it is best
to create your 3D geometries outside of eQuest if they are complicated
import them and then modify spaces in eQuest.

 

Thanks,

I haven't had much luck with customizing spaces either.  

I think there is a way to import a revit model file into equest.  If I
needed complicated zones & spatial geometry, I would probably consider a
revit license, but with that come's more money ($4-$6k for 1 standalone
license) and possibly more training, but might save a whole lot of headache.

 

Seems like equest is more of an energy modeler than an accurate building
modeler.

Dear all,

Once again, another problem!

I have several spaces which were geometrically modified in the design. For
example, a room that was split into two different ones; with each room being
a different hvac zone. How can I possibly split a room into two zones "1"
and "2"? Shall I modify the geometry of the old zone to be that of zone "1",
and then add another zone "2" from scratch? If this is what should be done,
how can I do this accurately?

Attached is the polygon view of one of my floors. When you look at them in
2-D or 3-D views, the building seems perfect in shape. Notice the rectangle
to the left of the picture! This is actually a zone that lies inside the
building. But it appears like this in polygon view. I think it is some
problem of coordinate references or so!
So when I need to modify the geometry according to coordinates of vertices,
I'm suffering!

Many thanks!
Omar
