How to adjust the "elevational view" of an object?

rob2218 — Tue, 12 Apr 2011 19:01:53 GMT

Can anyone here gimme the quick lowdown on the best way to adjust the 2d view "in elevation" of an objects programming code?

Meaning..I'm able to adjust how an object looks in plan by removing the 2d written script information in the 2d view but how do I do the same thing in the 2d elevational view the 3d model generates???

thanks,

The elevation view is an aspect of the 3D view. In the case you illustrate, I would guess that this is an imported object from another program. I believe that this could be fixed by adjusting the status settings of some of the objects in the code, but I can't tell you more without seeing the object's code since I do not import object very often.

Perhaps someone who does can give you more pointers or you could post the object to see if someone can clean it up.

YES....the object I imported came from 3dWarehouse from Google.
it's a Kitchenaid microwave/hood combo unit.

it's what I need but..as you can see the 2d elevational view generated from the 3d model object has hiddeous lines everywhere....I know how to make the 2d plan view simple but...the 2d elevational view??....humm...not sure there.

Anyone else feel free to chime in?....anyone, Bueller, Bueller?...

With the GDL editor open with the object, you can capture the 3D view to the Symbol editor and clean it up. Put it in its own Fragment. Clean up the plan view in its own Fragment. Then, a 2D script can test where it is being called from (plan or elevation/section) and display the appropriate symbolic view by turning on the appropriate Fragment.

Haven't tried this in many years, so cannot remember if there is any shifting (in coordinates) of the displayed symbols vs the actual 3D counterpart.

It seems like the process described above could be automated by the object importers (3ds, warehouse, etc) if GS had the time to spiff them up ... leaving the only work for users to be the visual editing of the symbols...

How does one actually "capture the 3d view to the symbol editor"? thats where I'm not sure what commands I'm doing.

How do you actually "put it in it's own Fragment"?

Set your 3D projection to be top or front view, set 3D engine to Internal, mode to Hidden Line, then click the Add to Symbol button shown in the attached.

Open the Symbol window and change the fragment (like layers) for the linework to one of the 16 fragments available. Write your script to make this display. (Maybe someone else will take the time to show you the script - kind of busy at the moment.)

Ah, yes! Karl, we can always count on you for sage advise. The beauty of this method is it does not rely on the model for the elevation view then. It is merely a 2D drawing much the same as the plan view.

GLOB_CONTEXT=4 will determine if your object is being viewed in a section or elevation but it won't determine the direction that it is being viewed from.
So the microwave will look the same in every elevation.
The trick then is to hide the layer of the object in side / rear view elevations if you don't need to see it in those.

If you do need to see it from all elevations then I think you are back to adjusting the code from the original object if you can to simplify it.

FRAGMENT2 fragment_index,use_current_attributes_flag
This is the command you need to show the fragment you create.

i.e.

if GLOB_CONTEXT = 4 then
FRAGMENT2 fragment_index,use_current_attributes_flag
endif

Right.
Spent the entire day doing taxes, so have a good excuse for my brain mis-firing. Hope the damage isn't permanent. 😉

Thanks, Barry.

sorry for coming to the party so late.. I am having the same issues but I need to have each elevation give a different projection. Could anyone tell me what parts of the code I would have to change so that different projections appear in each of the elevations.

To the best of my knowledge this is not currently possible. Unfortunately there is no global for the angle of view in a section. It seems like it would be a trivial matter for GS to provide. It may already have been put on the wish list but it certainly wouldn't hurt if you want to add a new wish for it.

Had something similar and did a cheeky move -
(by similar I mean needed some simple 2d line work to appear in elevation on a simple 3d box - think power and data - but the principal should be transferable)

When in the elevation/section environment replace the 3d model with a simple prism (cprism_ or slab - read on) and apply custom materials to the sides and top/bottom.
For the custom materials you apply a custom hatch which looks surprisingly like simplified elevations (made from lines and curves).
The process goes like this:

1] create your custom hatches of side and front elevations to the correct dimensions.
2] create you custom materials that use these hatches

3a] To get your material origin correct draw your prism in plan at 0,0, then manipulate it to your desired position.

I struggled with this at first so I:

3b] make a slab of the correct dimensions and apply the materials
in 3d, using the internal renderer, adjust the material origins to appear correctly
make an editable object from this slab
open and copy the 3d code
insert this code into your original 3d script with a " if glob_context = 4 then" at the front and don't forget your "endif" at the end. You also want to make sure that when it's in the 3d environment you get to see your nicely modeled object so use a similar glob_context command.

More than happy to hear of improvements on this method.

PS: also don't forget to turn on vectorial hatching in your elevation.

good luck
