PROJECT2{2} and fills

[Frank Beister]

I have a basic question again. The attached object ...

... is a block, cut by a CUTPLANE.

It has no certain fill in the 3D view, but in the 2D view there is a "brick" fill on the section area I don't know, where it's from. See picture below.

A complete thread just for me.

The (simple) explanation:
The surfaces, resulting out of CUTPLANES, inherit the material (and its 3D-fills), set before the CUTPLANE-command by SET MATERIAL. In my demonstration object none was defined, so AC took any fill/material.

I don't know exactly where it comes from, but when you use a cutplane command, the material used above the cutplane will be used for the resulting surface.

so I attatched a material parameter and a material definition in front of cutplane:

add 0,0,0.8
!                !!! define a new material parameter "matcpl" in parameter list
material matcpl  !!! this material will be used for the resulting surface
CUTPLANE
DEL 1

if matT="Symbol" then material SYMB_MAT else material "mat2D"

ROTX 45
ROTY 45
BLOCK 1,1,1
DEL 2
CUTEND

you will see this effect not only on the 2d-komplete view but also in the 3d view, if the 3d surface fill effect is "on" i 3d window settings.

best regards, gerd

U can see the material's fill with this cose

project2 mode, angle, 16 + type (1, 2 or 3)

like

project2{2} mode, angle, 16+ type (1,2 or 3), ......

and
project2{2} mode, angle, 48+ type (1,2 or 3), ......

but in the 2D view there is a "brick" fill on the section area I don't know, where it's from

1) U havn't definie a material (code) before cutplane
and ArchiCAD .. assign the first in default system's material
