IsRebarInSection()

MiguelGT17 — Thu, 05 May 2022 04:54:08 GMT

I have place a set of rebars in a viewPlan that only have 1 segment:

I was expecting the IsRebarInSection() command to throw a true boolean as the rebars are shown as a cross section. If that is not the case, what this method stands for and which api method should I be looking up instead?

Test code:

foreach (Element element in rebars) { if (element is RebarContainer) { } else if (element is Rebar) { Rebar el = element as Rebar; if (el.IsRebarFreeForm() == true) { } else if(el.IsRebarShapeDriven() == true){ RebarShapeDrivenAccessor acc=(element as Rebar).GetShapeDrivenAccessor(); XYZ dir=acc.GetDistributionPath().Direction; double angle=dir.AngleTo(view.ViewDirection); angle=angle*(180/Math.PI); //90,0 stb.AppendLine(angle.ToString()); stb.AppendLine(el.IsRebarInSection(view).ToString()); } } TaskDialog.Show("dd",stb.ToString());

Best Regards

And yet again: This sounds like a request for some in-depth rebar API expertise beyond my limited ken, so I asked the devteam for you. I hope we can find an efficient way to address your very valid questions.

IsRebarInSection(View view) returns true only if the view is a section or elevation and the view plane is cutting at least one of the rebar curves, false otherwise.

This API function is the correspondent of this UI option:

In your case, to see that the straight bar is shown as a point you can verify this on your own. You can get the centerline curves like this rebar.GetTransformedCenterlineCurves(false, true, true, MultiplanarOption.IncludeOnlyPlanarCurves, 0);, You will get only one line. If the line’s direction is parallel with view’s direction it means that the bar is shown as a cross section, false otherwise.
