Explode Planar Surface To 3d Meshes

[MR MAN]

Any One Know How Can I Explode Planar Surface To 3d Meshs

[ReMark]

Didn't you ask this very same question on June 30th of 2008? It seems very familiar. I guess you never got a satisfactory answer. You might try over at the AutoDesk Discussion Forums or the AUGI website.

Yes I Ask It Before But I Really Need It So,

Thanks Remark For Your Advise.

Since you haven't got very far with this question, can the problem be approached differently? Perhaps a mesh can be created from the objects you use to create the planar surface (so go directly from them to a mesh). How do you usually create the surface-what objects. And what type of 3dmesh do you need - is it one that "looks" just like the planar surface, with vertices on a square grid?

[MR MAN]

I CREATE MESHES LIKE THAT

IN COMMAND LINE 3D---MESH---AND I CHOOSE vertices (4 ONLY)TO MAKE MESH THEN CHOOSE NUMBER OF DIVISIONS IN M,N DIRECTIONS

AND I CREATE PLANAR SURFACE LIKE THAT

JUST MAKE ANY SHAPE BY POLYLINE COMMAND AND TYPE COMMAND PLANESURF THEN OBJECT TO SELECT OBJECT I NEED

THE OBJECT DIVIDE AUTOMATICALLY TO 6X6 V,U ISOLINES SO I NEED 3D--MESH COMMAND WORK LIKE PLANESURF COMMAND FOR EASY USE.

 

 

THANKS FOR HELP.

How about using the EDGESURF command to create a mesh. Or depending on the surface shape/type. RULESURF or TABSURF.

[MR MAN]

it work very good BUT it work for 4 surfaces ONLY can i increase them to any number i neeed?

 

 

 

 

 

THANKS FOR HELP CARIB

[MR MAN]

guys i wait for help

It may help us to understand the problem if you would provide some more information.

 

1-Give an example of the shape or shapes you are trying to "mesh". Are they closed polylines? Do they have any curved sides? Are they all really planar, and are they always parallel to one of the 3 principal planes (such as x-y, x-z, y-z)?

 

2. For these shapes, give an example or 2 of what the mesh would look like. Does the mesh have the same size grids, or can it be irregular.

[MR MAN]

1- YES they ARE closed polylines.

2- NO they haveN'T any curved sides.

3- YES they all really planar, and they ARE always parallel to X-Y PLANE.

4- YES the mesh have the same size grids.

FINALLY MY ATTACHMENT EXPLAIN WHAT I MEAN IN SHAPE "1" I MAKE PLANAR SURFACE AS SHOWN WITH ANY SIZE THEN WHEN I EXPLODE IT SHAPE "2" APPEAR TO ME AS YOU SHOW I NEED USING WAY WHICH YOU TELL ME BY EDGESURF TO MAKE 3D MESHES OR ANY OTHER WAY YOU SEE IT HELP ME

I don't believe thewre are any simple AutoCAD steps to create a mesh from other objects other than the "edgesurf" command, which as you note is for 4-sided objects. So you'd need some 3rd party software, or create a lisp or VBA routine to do this.

 

The example you show (made by "planesurf") has some 3-sided and some 5-sided "grids" or "faces" within the mesh. Some rows have more faces than others. The 3dmesh command makes generally 4 sided faces, same number in each row. You can stack vertices & make a 3-sided face. So how would you make that irregular shape using 3dmesh?

 

Alternatively you could create a polyface mesh ("pface" command). Would your analysis program be able to use this object type?
