Currently I have an object drawn using the AutoCAD class but I the option to mirror it once drawn. I'm not sure how to go about this.
[CommandMethod("DrawTestDoor")]
public void DrawTestDoor()
{
Document acDoc = Application.DocumentManager.MdiActiveDocument;
var ed = acDoc.Editor;
XDDoor s1 = new XDDoor();
PromptKeywordOptions pKeyOpts = new PromptKeywordOptions("");
pKeyOpts.Message = "\nIt is Rated ";
pKeyOpts.Keywords.Add("True");
pKeyOpts.Keywords.Add("False");
pKeyOpts.Keywords.Default = "True";
pKeyOpts.AllowNone = true;
PromptResult pKeyRes = acDoc.Editor.GetKeywords(pKeyOpts);
bool fireRated = Convert.ToBoolean(pKeyRes.StringResult);
var promptResultheight = ed.GetString("\nEnter the Frame height: ");
double height = Convert.ToDouble(promptResultheight.StringResult);
var promptResultwidth = ed.GetString("\nFrame Width: ");
double width = Convert.ToDouble(promptResultwidth.StringResult);
var promptResultFrameDepthChange = ed.GetString("\nEnter the frame depth change ");
double frameDepthChange = Convert.ToDouble(promptResultFrameDepthChange.StringResult);
PromptKeywordOptions pKeyOpts1 = new PromptKeywordOptions("");
pKeyOpts1.Message = "\nDoor Handle Side";
pKeyOpts1.Keywords.Add("Left");
pKeyOpts1.Keywords.Add("Right");
pKeyOpts1.Keywords.Default = "Left";
pKeyOpts1.AllowNone = true;
s1.DrawSingleXDDoor(height, width, fireRated, frameDepthChange);
Matrix2d md = new Matrix2d();
md.Translation.Mirror()
}
This md.Translation.Mirror()
is the line that I think needs changed. I have tried numerous ways to do the mirror but I keep coming back to the issue with I dont know what the s1
object is being saved as as such. Maybe thinking it needs converted to an entity?
public void DrawSingleXDDoor(double height, double width, bool fireRated, double frameDepthChange)
{
DrawLid("lid", leafHeight, lidWidth);
}
public void DrawLid(string type, double height, double width)
{
DrawShapes d1 = new DrawShapes();
DrawComponents xd = new DrawComponents();
d1.DrawRectangle(0, 0, height, width);
}
public void DrawRectangle(double startx, double starty, double recHeight, double recWidth)
{
double height = recHeight;
double width = recWidth;
//Get the drawing document and the dataabses object
Document doc = Application.DocumentManager.MdiActiveDocument;
Database db = doc.Database;
using (Transaction trans = db.TransactionManager.StartTransaction())
{
try
{
BlockTable bt;
bt = trans.GetObject(db.BlockTableId, OpenMode.ForRead) as BlockTable;
BlockTableRecord btr;
btr = trans.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite) as BlockTableRecord;
Polyline p1 = new Polyline();
p1.AddVertexAt(0, new Point2d(startx + 0, starty + 0), 0, 0, 0);
p1.AddVertexAt(0, new Point2d(startx + 0, starty + height), 0, 0, 0);
p1.AddVertexAt(0, new Point2d(startx + width, starty + height), 0, 0, 0);
p1.AddVertexAt(0, new Point2d(startx + width, starty + 0), 0, 0, 0);
p1.AddVertexAt(0, new Point2d(startx + 0, starty + 0), 0, 0, 0);
p1.SetDatabaseDefaults();
btr.AppendEntity(p1);
trans.AddNewlyCreatedDBObject(p1, true);
trans.Commit();
}
catch (System.Exception ex)
{
doc.Editor.WriteMessage("Error encountered: " + ex.Message);
trans.Abort();
}
}
}
It has taken me till now to figure this out. Many trials and errors. I will do my best to give as much code as possible with an example
arrays.cs
public void PopulateWithOldArray(List<double> newArray, List<double> oldArray, bool negate)
{
//if there are any previous version of the new array we want them to be cleared so that the called old array will not be affected
newArray.Clear();
if (negate == true)
{
for (int i = 0; i < oldArray.Count; i++)
{
newArray.Add(-oldArray[i]);
}
}
else
{
for (int i = 0; i < oldArray.Count; i++)
{
newArray.Add(oldArray[i]);
}
}
}//end PopulateWithOldArray
public void MirrorXaxis(double startx, double starty, List<double> x, List<double> y, List<double> angle)
{
List<double> changedx = new List<double> { };
List<double> changedangle = new List<double> { };
PopulateWithOldArray(changedx, x, true);
PopulateWithOldArray(changedangle, angle, true);
DrawShapes ds = new DrawShapes();
for (int i = 0; i < angle.Count; i++)
{
ds.DrawPolyLine(changedx[i] + startx, y[i] + starty, changedx[i + 1] + startx, y[i + 1] + starty, changedangle[i]);
}//end for
}//end mirror
