Dimensions disappearing on insert

moshebar — Thu, 10 Aug 2017 09:18:06 GMT

when programmatically making dimensions between two points all the dimensions become invisible within an active sketch, as it they were set to hide..

has anyone else encountered this?

It's not clear what the workflow is in your case. Can you explain in more detail the steps to reproduce the problem or provide some sample code that demonstrates it? Thanks.

Hi,

the original code is too spaghetti - convoluted, here is a simplified recreation:

extern "C" XI_EXPORT bool run(const char* context)
{
	app = Application::get();
	if (!app)
		return false;

	ui = app->userInterface();
	if (!ui)
		return false;

	//ref active sketch
	Ptr<Base> active_base = app->activeEditObject();
	if (!active_base)
		return false;
	//cast to sketch
	Ptr<Sketch> sketch = active_base;
	if (!sketch)
	{
		ui->messageBox("can only edit an active sketch");
		return false;
	}
	

	//ref points
	Ptr<SketchPoints> points = sketch->sketchPoints();
	if (!points)
		return false;

	//ref 3d sketch origin
	Ptr<Point3D> D3origin = sketch->origin();
	if (!D3origin)
		return false;

	//make a sketch point at origin
	Ptr<SketchPoint> sketch_origin = points->add(D3origin);
	if (!sketch_origin)
		return false;
	sketch_origin->isFixed(true);




	//create dimensions object
	Ptr<SketchDimensions> dimensions = sketch->sketchDimensions();
	if (!dimensions)
		return false;

	//traverse points
	for (size_t j = 0; j < points->count(); j++)
	{

		//ref the sketch point
		Ptr<SketchPoint> point = points->item(j);
		if (!point)
			continue;


		//add dimensions to non constrained points
		if (!(point->isFullyConstrained()))
		{
			//Ptr <Point3D> point_3D = point->worldGeometry();
			//if (!point_3D)
			//	continue;
			Ptr<Point3D> textPos = point->geometry();
			if (!textPos)
				continue;


			Ptr<SketchLinearDimension> sketchDimension1 = dimensions->addDistanceDimension(sketch_origin, point, HorizontalDimensionOrientation, textPos, true);



			//if still un constrained add second dimension
			if (!(point->isFullyConstrained()))
			{

				Ptr<SketchLinearDimension> sketchDimension2 = dimensions->addDistanceDimension(sketch_origin, point, VerticalDimensionOrientation, textPos, true);

			}

		}

	}



	return true;
}

if you run this scrip on an active sketch with unconstrained points, the result does not display the dimensions. you need to reload the sketch to see the created dimensions.

Thanks

Thank you for the sample code. I'm able to reproduce the problem and have logged a bug.

Hi,

I think I'm encountering the same thing and when you programatically add dimensions they are hidden by default. See this thread to see how to turn them on manually.....I'm currently trying to find out how to do this programatically.
