Hello JoĂŁo, I will take a look at your drawing but :
Primeiro, verifique a fase 3 do desenho anexado para mim criar as extrusões corretas.
O que tem que fazer com :Rede de Refrigeração - Prumadas Ø 1 e 1.2 ?

Hi,

I have another problem with other drawing.

With the geometry of this drawing is so easy that only need to use the command LOFT. But i can't JOIN (PEDIT) all polylines to make a SOLID. I only need the volume of all block.

I have miss some command, to make this right. that could be easy, i think, but i dont have many experience...

Could you help me?

Bomdia JoĂŁo, I did a 3D work based on your file, see the steps that I take from 1 to 18.
The result is on step 5.
I had to do 5 files to upload them, rebuilt it by inserting xxxxx-2 to xxxxx-5 in xxxxxxx-1.dwg
tell me if this helped or not.

Thanks to reply my answers,

This is so simple idea that i didn't remember.

I try to do the way that you advice me, with the 1,5 rectangle, but i cant do it, because i cant transform the block (between the betao p303 e linha de corte layers) in a solid.

If was simple with no solid out of bounderies of block like the others in the dam, is easy... but since this its all like this difficult way.

I think i'm getting wrong in any point...

Hello again JoĂŁo, I have open your 3D file.
I supose that you want to work with the 2 polylines in the middle "Linha Corte" and "Betao PU303" and I supose that you want to joint them with a 3D solid likr the 3DSOLID layer: "Linha Corte" on the right.
I supose also that the assembly of surfaces and polylines on the left is the result that you want to know the volume.
The 2 polylines in the middle are at elevation "0" and "1.5" exactly so I would do a big solid height 1.5 and add or remove material to have the final result.
In any case do a copy at an exact distance for each 3D modification so that you can go back or modify safely.
Eventually see my file "3D SOLID 01.dwg that you can find in the CAD/BIM Blocks directory here in the site, launch a search with the file name complete or partial name.
To create 3D surfaces between 2 curves located in 3D try : EDGESURF or RULESURF for example.
Please let us know if this helped or not.

Also to know : if you LOFT closed surfaces modified with the command REGION you will get solids and not surfaces.

HELLO philippe JOSEPH

First of all thanks for your's quick answer.

I try to do the EXTEND and i got the polylines intercept. But when i JOIN the polylines, i think i have problems, because they don't close all polylines. Mainly in the low bonderie.

Did i made something wrong?

I dont know any command to generate curves in autocad 3D, and i only work in English autocad .

Hello JoĂŁo bomdia, for the polylines I recommand to EXTEND and not STRECH them because you will change the polyline.
For AutoCAD 3D you can use commands to generate curves with facets between 2 curves located in 3D and then use these surfaces with facets to generate solids.
Surfaces and solids shouldn't be a problem on dams because the concrete that you will bulit will be like this I think.
Ask for these commands if necessary.
Eventually if you use AutoCAD with a portuguese release take a look at the dictionnary to tranlate the commands in different languages.
