I needed a left triangle & a right triangle to make the shape I need in idea studio.

I thought could make two right triangles & mirror one of them but the mirror feature doesn't work with shapes, only with images.

I'm editing the pages .SRC now but that feels to me like a lot of work to do something which should be routine.

I muse be overlooking something basic here. What do others do?

Those shapes are all paths which can be easily edited to any shape you like. The cool things about VTScada and the idea studio is that you can copy any object (such as a shape) into a text editor, make your edits, and then paste that text back into the idea studio to create the updated object.

Copy the code below then click on a page in the idea studio and CTRL+V paste it into the idea studio. You should see the triange you are looking for:

  GUIPolygon(0, 141, 100, 41,
             1, 1, 1, 1, 1 { Scaling              },
             0, 0          { Movement             },
             1, 0          { Visibility, Reserved },
             0, 0, 0       { Selectability        },
             Brush("<FFA0A0A0>", 0, 1), Pen("<FF000000>", 1, 1),
             Path(1,
                  Vertex(1, 
                         Point(100, 0, Invalid, Invalid),
                         Point(100, 0, Invalid, Invalid),
                         Point(100, 0, Invalid, Invalid)),
                  Vertex(1,     
                         Point(100, 100, Invalid, Invalid),
                         Point(100, 100, Invalid, Invalid),
                         Point(100, 100, Invalid, Invalid)),
                  Vertex(1,    
                         Point(0, 100, Invalid, Invalid),
                         Point(0, 100, Invalid, Invalid),
                         Point(0, 100, Invalid, Invalid))));

Thanks Dave for explaining that I'm not making extra work by editing the source to do something that feels routine.

Thanks as well for that copy & paste trick. I'll give that a try next time I need to modify a single object.
