Best way to draw solid in 3D space

[g.iannetta]

Hello,

what is the best way to draw one solid in 3d space?

I need draw 3D object in different position, different coordinate and different inclinations.

Hi,

create the solid in WCS. Next create a matrix that defines the position/rotation/scaling and use ,TransformBy to get the solid to where you want to have it.

Good luck, - alfred -

Check out the "Create 3D Objects" section in the .NET development guide.

Hi,

>> please give me more information to create the trasformation matrix...

Look at >>>this blog<<< about understanding AutoCAD Matrix3D.

hello,

the translation matrix is very powerful we can modify (rotate, traslate,scale, etc) but is very hard to use...

we can use other Matrix3D funcion:

Matrix3d.Rotation

Matrix3d.Scaling

Matrix3d.Displacement

remenber that we work in 3D space and we need rotate the objetc in 3 axix...
