How to get dimensions from sketch??

[Anonymous]

hi 

i need to get dimensions from sketch

here is the code

Element e1 = (Element)Fmly;
ElementId eid = e1.Id;

Transaction t = new Transaction(doc, "fake");
t.Start();
ICollection<ElementId> ids = doc.Delete(eid);
t.RollBack();

foreach (ElementId id in ids)
{
Element ele = doc.GetElement(id);
string name = ele.Name;
list1.Add(name);
if (ele is Sketch)
{
Sketch s = (Sketch)ele;
string name4 = ele.Name;
SketchPlane sp = (SketchPlane)doc.GetElement(name4);
CurveArrArray caa = s.Profile;
foreach (CurveArray ca in caa)
{
foreach (Curve c in ca)
{

}
}
}
else if (ele is Dimension)
{
Dimension d = (Dimension)ele;
string dname = d.Name;
string dvalue = d.Value.ToString();
}

Hi! The idea of an element deletion + temporary transaction seems good for me. But source element must have a sketch in such case, e.g. source element should be a Floor, for example.

I think you need to improve your code: first of all, find sketch in ids list, get all model curves references, then find dimensions in this list and filter them - sketch dimensions must have references to sketch model curves (just compare stable representations)

hi 

i am looking to get the sweep/extrusion pathsketch dimensions.

first i am getting the sweep profile and then traversing the curves in the profile..apparently i am getting the wrong dimensions

can you help me out here??

where am i wrong??

Transaction t = new Transaction(doc, "GetElementId's");
t.Start();
ICollection<ElementId> ids = doc.Delete(eid);
t.RollBack();
List<string> sweeplist = new List<string>();

foreach (ElementId id in ids)
{
Element ele = doc.GetElement(id);
string name = ele.Name;
list1.Add(name);

if (ele is Sweep)
{
Sweep s1 = (Sweep)ele;
Sketch s2 = s1.PathSketch;
SketchPlane sp = s2.SketchPlane;
CurveArrArray caa = s2.;
foreach (CurveArray ca in caa)
{
foreach (Curve c in ca)
{
string cleng = c.Length.ToString();
}
}
}
}

I'm not sure about what you want to achieve.

Perhaps, this will help you:

public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
{
	var uiapp = commandData.Application;
	var uidoc = uiapp.ActiveUIDocument;
	var doc = uidoc.Document;

	var collector = new FilteredElementCollector(doc);

	var sweep = (Sweep) collector
		.OfClass(typeof (Sweep))
		.FirstElement();

	var profileCurves = sweep
		.ProfileSketch
		.Profile
		.Cast<CurveArray>()
		.SelectMany(x => x.Cast<Curve>());

	TaskDialog.Show("dev", $"Profile curves length: {UnitUtils.ConvertFromInternalUnits(profileCurves.Sum(x => x.Length), DisplayUnitType.DUT_MILLIMETERS)} mm");

	return Result.Succeeded;
}

hi

UnitUtils.ConvertFromInternalUnits(profileCurves.Sum(x => x.Length), DisplayUnitType.DUT_MILLIMETERS)} mm");

thank you  @aignatovich  for this. i didn't see the units. when i run my code the length is not in mm..

so thanks for helping me out.
