Explode and Select Window in C#
I'm trying to identify the label inside the sheet. Using the boundary of the line, I will able to select the object and Identify the label that I marked. In this case (063, 064, 067, 068, 069)
OR can you using
TypedValue[] tvs = new TypedValue[]
{new TypedValue(0, "text")
};
SelectionFilter filter = new SelectionFilter(tvs);
PromptSelectionResult result = ed.SelectCrossingWindow(p1, p2, filter);
if (result.Status != PromptStatus.OK) return;
@alexisgacia The Explode method does not add the objects to the database so selection won't find anything. If you post a small dwg along with the code you are using to the select the region(s) we could probably get this sorted out for you.
Hi @Jeff_M and @hosneyalaa,
Good day.
I attached the DWG File as reference.
User Steps:
Select BlockReference as BlockSheet
Select Target Entities (Circle, Line, Polyline, SPLine)
Desired Output:
Circle (Cyan): 053, 054, 060 & 061
Line(Green): 067
SPLine(Yellow): 056, 057, 061, 062 & 063
Polyline(White): 069, 070, 072, 073 & 074
Block <BlockSheet>: Contains Polyline and Text
Polyline ("A-TITL-TXT2" & "Z_DWG_SHT")
TEST ("Z_DWG_SHT_NO")
My idea on the process:
Explode the BlockSheet to SheetCollection
Remove any objects except objects having layer ("Z_DWG_SHT" & "Z_DWG_SHT_NO")
Loop through to Selected Entities
(SelectCrossing or Alternative function) using boundingbox of the entity as Crv1 to identify the objects in SheetCollection.
(SelectCrossing or Alternative function) Using the boundary of the entity as Sheet having layer "Z_DWG_SHT" from the sheetCollection to check if Crv1 exist in the selection
Once Crv1 exist grab the Text with layer "Z_DWG_SHT_NO"
Currently I don't have an alternative function that can SelectCrossing in the Collection.
Below is the sample code that I did
private void _SelectObjectsFromExploded(object sender, EventArgs e)
{
Autodesk.Civil.ApplicationServices.CivilDocument civilDoc = Autodesk.Civil.ApplicationServices.CivilApplication.ActiveDocument;
var doc = Application.DocumentManager.MdiActiveDocument;
var db = doc.Database;
var ed = doc.Editor;
listBox1.Items.Clear();
string mSheetBlockName = "SheetBlock";
string mSheetLayerName = "Z_DWG_SHT";
string mLabelLayerLName = "Z_DWG_SHT_NO";
cSelection mSel = new cSelection();
ObjectId mSheetBlockId = mSel.Select_SingeEntity("Select Sheet Block");
// Set up our selection to only select 2D solids
var pso = new PromptSelectionOptions();
pso.MessageForAdding = "\nSelect Curve";
//var sf = new SelectionFilter(new TypedValue[] { new TypedValue((int)DxfCode.Start, "3DSOLID") });
//var psr = ed.GetSelection(pso, sf);
var psr = ed.GetSelection(pso);
if (psr.Status != PromptStatus.OK) return;
using (doc.LockDocument())
{
DBObjectCollection mSheets = new DBObjectCollection();

doc.TransactionManager.EnableGraphicsFlush(true);
using (Transaction tr = doc.TransactionManager.StartTransaction())
{

if (oBlk is BlockReference)
{
oSheet = oBlk as BlockReference;
if (oSheet.Name.ToUpper() != mSheetBlockName.ToUpper())
{
ed.WriteMessage("\nSelected block is not recognize as Block Sheet.");
return;
}
// Create Temp Sheets
oSheet.Explode(mSheets);
mValidSheets = GetValidSheets(tr, mSheets);

tr.Commit();

@alexisgacia Is the new code doing what you want? I got called away for a family emergency so have not had a chance to look into this further. Your new code is doing pretty much what I was going to attempt. The last step for the text would just loop through the text objects and see if the insertion point is inside the 'selected' sheets.
