I have a utility that creates horizontal dimension and places the dimension text in the middle of the 2 extension lines.
To determine the middle of the extension lines, I used IDisplayData::GetLineAtIndex3 to get the data needed then perform the computation as shown below:
IDisplayData disData = (IDisplayData)tempDim.GetDisplayData(); double lineData1 = (double)disData.GetLineAtIndex3(0); double lineData2 = (double)disData.GetLineAtIndex3(1); // Calculate center; double center = lineData1 + ((lineData2 - lineData1) / 2.0);
The utility works fine until I had to insert a break(View:: InsertBreak) in one of the drawing views that I`m working on,
the dimension text position is being placed in the wrong position.
Upon investigation, I found out that the value of lineData1 and lineData2 interchanged so the formula was affected.
I tried deleting the break line then re-create dimensions, and then the text was placed in the right position.
Based on this behaviour, I concluded that the break line is causing the problem, but I may be wrong.
Is there a way to prevent IDisplayData::GetLineAtIndex3 from interchanging the lineData1 and lineData2?
If none, what alternative function can I use to position the dimension text in the middle?
Thanks is advance.
