Starting from Eyeshot 2020, we introduced a new property of type AutodeskMiscProperties of the Entity class called AutdoeskProperties. This class gathers inside it some miscellaneous Autodesk properties such as curve thickness, the thickness extrusion direction, and the entity XData.  Now to read and write the entity XData you need to proceed as follows:  Li…

This article explains the basic concept of assembly navigation. For a better understanding, it is recommended to read the RootBlock article first. For an advanced implementation of this feature, you can see the code of the AssemblyDemo sample. Take for example a simple scene with two blocks, in addition to the root one. Block red = new Block("Red"); red.Entities.Add(Brep…

In Eyeshot ProgressBar can be used only in asynchronous WorkUnits (the ones ran with model.StartWork()). In case you would like to use ProgressBar in a synchronous way, independently from WorkUnits, updating its value when needed and then calling Invalidate(), you can use this trick:   Derive ProgressBar class and expose its Draw method: public class MyProgressBar : de…

Animation is performed only on the GPU, entities are not truly moved, vertices and bounding box don't change, collision detection doesn't work and so on. To edit entities position you can apply a transformation, but the computation is heavier and the animation slower. You can see the difference between these approaches in the Assemble sample. The steps to animate a…

Subscribing to CompositionTarget.Rendering is sometimes useful or even needed but should be used wisely because it forces WPF to constantly render window. For this reason, starting from Eyeshot 12, we introduced the NativeExperimental renderer to stop using this event for rendering. When I should use the NativeExperimental renderer? If you experience a pe…

Import Supposing you want to import an OBJ file (all the import methods follow the same scheme) you need the ReadOBJ class. This class gives you full control over all the imported items (entities, blocks, layers, materials, etc.) before adding them to the scene. During file import, you can also control whether to read the file synchronously or asynchronously. Read from s…
