How to use AddRegion?

[Anonymous]

Hi,

I'm trying to create a region that is a circle, and then I want to access to that region to get area, perimeter, etc. Of course with a circle is easy to get the area and perimeter, but this is just a test of creating regions to be able to make different shapes in the future and get area/perimeter. This is the code:

using AutoCAD=Autodesk.AutoCAD.Interop;
using AutoDesk=Autodesk.AutoCAD.Interop.Common;
......
AutoDesk.AcadCircle circleObj;
double[] centerPoint = new double[3];

centerPoint[0] = 100.0;
centerPoint[1] = 100.0;
centerPoint[2] = 0.0;
circleObj = gbl_doc.ModelSpace.AddCircle(centerPoint, 50);

Object[] ol = new Object[1];
ol[0] = (AutoDesk.AcadEntity)circleObj;
Object[] regions = (Object[])gbl_doc.ModelSpace.AddRegion(objectlist);

I get an error "Matriz de objeto no valida" (spanish) that means something like "object array invalid".

Questions related to using the ActiveX API usually get more attention in the VBA/ActiveX newsgroup, regardless of the langauge used.

My guess is that your array must be typed as AcadEntity[] rather than Object[]

Hi, thanks, finally I managed to do it, actually it was relatec with using AutodeskObject instead of Object.

On the other hand, I cannot find VBA/ActiveX newsgroup, only forums I can see are:

.NET
Visual LISP, AutoLISP and General Customization Issues
Visual Basic Customization
Autodesk ObjectARX
Issues

Maybe you mean VB Customization or you are talking about a proper newsgroup (that is, using newsreader, nttp). Please, can you point me to the correct place? 🙂
