I'm trying to move a face in a solid3d via code . You can consider a simple box. I'm not able to understand how can I obtain the SubEntityID[]
needed to perform the methods without selection
SubentityId[] subEntsID = ????
mySolid.ExtrudeFaces(subEntsID, 100, 0);
s.TransformFaces(????,ecc..)
thanks in advance for any idea!

... perform the methods without selection
What does your program know about the solid ??
how will the program know which face to move ??
what have you tried ??
are you familiar with acdbmgdbrep.dll ??
-
ok...
using (Transaction t = d.TransactionManager.StartTransaction())
{
Solid3d s = t.GetObject(IdSolid3d, OpenMode.ForWrite) as Solid3d;
//// found the face...
using (AcBr.Brep brp = new AcBr.Brep(s))
{
ObjectId[] ids = new ObjectId[1];
ids[0] = s.ObjectId;
SubentityId index = new SubentityId(SubentityType.Null, 0);
FullSubentityPath path = new FullSubentityPath(ids, index);
s.Highlight(path, true);
Extents3d e = s.GeometricExtents;
AcBr.BrepFaceCollection facce = brp.Faces;
IList<AcBr.Face> faccedaspostare = new List<AcBr.Face>(0);
foreach (AcBr.Face [color=blue]f[/color] in facce)
{
IList<Point3d> ptfaccia = new List<Point3d>(0);
AcBr.FaceLoopCollection fl = f.Loops;
foreach (AcBr.BoundaryLoop l in fl)
{
so I Have a acbrface...and I Know the face that I want to move.
How can I get th subentityID about a face (or more faces) ?
And other question is ... Why the property "f.SubentityPath" just to see the value throws an exception ?
-
can you post all the code and the drawing .. I'll try to have a look early tomorrow .. won't have much time , sorry.
Is the face you want planar ??

that's all..
The top faces must be moved and i don't understand how can I take the entities :( without user selection
thanks for Your help. Any idea is always better of mine..now.
-
without studying your code too much, if you can get the face, dig deeper to get each vertice (using the traversal classes) of the face from it's edges and transform the vertices and the edges and face should follow.
hth
-
no. it's not right.
1) You can't apply a transform at acbr vertex.
2) If You apply a transform at Point (property of vertex) nothing happens
:realmad:
some words in Autodesk discussion groups sounds bad..like
There's little API support for solid modeling in AutoCAD
because Autodesk doesn't want them to be programmable.
http://discussion.autodesk.com/forums/thread.jspa?messageID=6356439� (http://discussion.autodesk.com/forums/thread.jspa?messageID=6356439�)
I don't want to believe it and I'm sure that a solid could be modified in a dimension.. isn't it?
-
I ran into this same issue when writing the routine in this post:
http://www.theswamp.org/index.php?topic=30499.0
At the time I assumed it was because the SubentID wasn’t created until it could be associated with the appropriate graphical elements.
Now, looking at your situation where there shouldn’t be any problem getting Face.SubentityPath, it does seem a bit suspicious.
There may be more avenues to explore, I’ll post back if I find anything.
-
A couple of irritating quirks have come to light here:
It would appear that there is some initialization going on that does not occur with the Editor.GetEntity, hence the problem with “f.SubentityPath”. The initialization is available with Solid3d.GetSubentityPathsAtGraphicsMarker, however, so it is possible to get a valid SubentID from the backside.
The other quirk is that the SubentityId[] requirement for all of the SolidEditing “Faces” methods is not implemented as the documentation states. I can’t find an object/array that is compatible. The SolidEditing “Face” methods do seem to work, and is what I used as a workaround in the sample.

that's Works!!! Thank You very much SEANT! I haven't idea to loop around with
fsP = s.GetSubentityPathsAtGraphicsMarker
(SubentityType.Face, i, pt, mtrx, numIns, ids); //If GSM points to face
Autodesk.AutoCAD.BoundaryRepresentation.Face brepFace = new Autodesk.AutoCAD.BoundaryRepresentation.Face(fsP[0]);
and try/catch to iterate..
But for me is a mistery the method exposed in api for brep.."extrudefaces"

I agree. That situation is rather irritating.
Perhaps one of our C++ proficient brethren could test that in native ARX to see if and how those particular methods work. :angel:

ahlzl,
Thanks for testing that for me.
It is a shame that the .NET wrapper is not working as expected. :-(
I suppose this is another indication that stepping up to native ARX is a worthwhile endeavor.

Wrapper to C#, Success!(CAD2008 + VS2005)
step1: Create a new ARX project
step2: Add a class: MyClass
step3: In MyClass.h, Add code:
#include "tchar.h"
step4: In MyClass.cpp, Add code:
extern "C" __declspec(dllexport) AcDb3dSolid* GetSubentIndexs()
{
AcDbObjectId entId = NULL;
AcArray<AcDbSubentId*> subIdArr;
AcEdSolidSubentitySelector subSel;

for (int i = 0; i < subIdArr.length(); i++)
{
index = (int)(subIdArr[i]->index());
_itow(index, indexStr, 10);
if (i == 0)

rb.restype = RTSTR;
rb.resval.rstring = subIdIndexStrs;
acedSetVar(_T("users1"), &rb);
return pSolid3d;

return NULL;
}
step5: Compile, Generate *.arx file.
step6: copy the file to AutoCAD Support Directory

Good start! a couple of small issues, first, in the ARX you have a memory leak at subIdArr, you need to iterate the array and delete the pointers, Second you pass an object that's opened for write, when you should probably pass an ObjectID :-)

Thanks for the effort guys. When I do make the jump, the study material here - and the other forum sections - will undoubtedly make the water more inviting. :-)
doh, I see that was already in the API :laugh:
It is in the .NET API, but the method appeared to be setup incorrectly (AutoCAD 2009). I'll look through these later posts for clues to a straight .NET solution. I certainly wouldn't be surprised if I missed something on my first go.
