feat.IsSelected does not work for feat type = "PLANE"

[MabeProductique]

Try this code on version = Xarial.XCad.0.8.0-beta.4687

//name = name of a plane

bool result = doc.Features.TryGet(name, out IXFeature feat);
feat.Select(false);
if (!feat.IsSelected)...

current workaround
result = doc.Model.Extension.SelectByID2(name, "PLANE", 0, 0, 0, false, 0, null, 0);

This is an interesting issue. The problem is features in SOLIDWORKS expose 2 interfaces (IFeature) and a specific interface (e.g. IRefPlane). Depending on the way it is selected the actual selected object is either IFeature or IRefPlane and the dispatches are different so the comparison returns false. As xCAD IXFeature combines both of these in a single type (e.g. IXPlane), it makes sense to consider this case. Dev version has a fix for this and now handles both cases

Thank you for your efforts ;)
