Topic: stack rectangles

[nobody]

I am trying to stack rectangles between certain distances inside a selected polyline. I have the east west figured out, but not sure how to solve the north south at the same time.  Any help appreciated.

Code - C#: [Select]

1.  ObjectId rectangleboundary = CreateRectangle(pline.GeometricExtents.MinPoint, pline.GeometricExtents.MaxPoint);
2.  
3.                 double eastwestdist = Math.Abs(pline.GeometricExtents.MinPoint.X - pline.GeometricExtents.MaxPoint.X);
4.                 double northsouthdist = Math.Abs(pline.GeometricExtents.MinPoint.Y - pline.GeometricExtents.MaxPoint.Y);
5.  
6.                 double topleftx = pline.GeometricExtents.MinPoint.X;
7.                 double toplefty = pline.GeometricExtents.MaxPoint.Y;
8.                 Point3d topleft = new Point3d(topleftx,toplefty,0);
9.  
10.                 double distance = 30;
11.                 double checkhorz = 0;
12.  
13.                 while (checkhorz < eastwestdist)
14.                 {
15.                      rectangleboundary = CreateRectangle(new Point3d(topleft.X + checkhorz,topleft.Y,0), new Point3d(topleft.X + checkhorz + distance, topleft.Y - distance, 0));
16.                     checkhorz = checkhorz + distance;
17.                 }

Thanks!

Hi,

Here's a way:

Code - C#: [Select]

1.                 var extents = pline.GeometricExtents;
2.                 CreateRectangle(extents.MinPoint, extents.MaxPoint);
3.  
4.                 int eastwestNum = (int)((extents.MaxPoint.X - extents.MinPoint.X) / 30.0);
5.                 int northsouthNum = (int)((extents.MaxPoint.Y - extents.MinPoint.Y) / 30.0);
6.  
7.                 Vector3d horizDisp = new Vector3d(30.0, 0.0, 0.0);
8.                 Vector3d vertDisp = new Vector3d(0.0, 30.0, 0.0);
9.  
10.                 Point3d p1 = new Point3d(extents.MinPoint.X, extents.MaxPoint.Y - 30.0, 0.0);
11.                 Point3d p2 = p1 + horizDisp + vertDisp;
12.  
13.                 for (int i = 0; i < northsouthNum; i++)
14.                 {
15.                     Point3d ll = p1;
16.                     Point3d ur = p2;
17.                     for (int j = 0; j < eastwestNum; j++)
18.                     {
19.                         CreateRectangle(ll, ur);
20.                         ll += horizDisp;
21.                         ur += horizDisp;
22.                     }
23.                     p1 -= vertDisp;
24.                     p2 -= vertDisp;
25.                 }

Thank you giles, always
