solid 3d with curved surface

[asdrubale23]

Hello everyone, excuse the question maybe stupid.. .

I have to draw a solid (building) with the curved roof (example below), and all must be extruded. .
Until the solid extrusion there are, I don't know how to make the curved roof. .
Give me a hand? ?
Thank you.

There are two possibilities, the easiest of which is the following.

draw the already 'curved prospectus (the one in the foreground in your sketch) and extrude it, finally ruoti all 90° with the command _rotate3d.

Thank you. . .adesso remains only to fill with a restraint the roof...and does not fill it neither in 2d nor in 3d
Why? ?
Usually to fill the faces in 3d use the bird at 3 points

Yeah, but your roof isn't a curved face.

my knowledge unfortunately stops at the 2006 version, but I do not exclude that higher versions allow to sample objects like your roof.

with acad2006 the only trick would be to associate it with a material similar to your dosing, with cylindrical mapping, and make it.

OK thanks you were very helpful! ! !

I recovered from the cache the initial sketch of asdrubale23, disappeared (lack because) from his first post:

curious the disappearance of the example. Thanks antoniov!
for the problem of the retino, perhaps you have to explode the solid obtained, and try to apply the deduction to the faces that revenues after the explosion.

 

[AntonioV]

apply the deduction to the faces that revenues after the explosion.

But you wouldn't have been holding up between the various faces.

I wonder if there is a cad that allows to sample Kurdish objects, I mean by vector and maybe associative restraints. . .

I also confirm for later versions. the dash is an entity 2d therefore not "mappabile" on curves.

is not a "real" mapping, but on solids or surfaces with curves just mentioned, non as in the image, projectgeometria (projectgeometry) makes its dirty figure.

:smile:

mah here. we talk about "any surface", meaning that the miraculous command moves on every type of receiving object.

but if you give the _list command to the projection, it is simple exploded lines or something new not exportable to autocad before 2011.. ?

... it is simple lines exploded or something new not exportable to autocad before 2011.. ?

are simple lines, arches, spline.. .

from the help: "projectogeometria - project points, lines or curves on a surface or a solid 3d [no mesh, si regioni - NDR] from different directions."

 

[AntonioV]

Be kind, when you have a moment of time, try to sample a rectangle with _hatch's ar-rshke pseudo-tegoles, raise it more than you can towards the concave ceiling, and finally project: how does it look?

I wonder how much it affects the distance between "projector" and "projected" on the final effect, thank you.

[GP.]

the distance between projected and projecting is influential, the entities are "fixed" along a trajectory parallel to the ucs, to the view or specified by two points.
