In the **Options** settings, you can choose which discretization will be applied on your CAD shape, i.e. how fine the shape will be sampled into a discrete representation. 1. If you choose **Current deflection**, then the deflection will be set from the current display. 2. If you choose **Absolute deflection**, then the maximum deflection between the CAD model and the discretized shape will be below the chosen distance. 3. If you choose **Adaptive deflection**, then the deflection will be different for each sub-element of the CAD model. The chosen ratio will be used as a guide to compute a local, adaptive deflection for each sub-element. 2. You can choose to use the same orientation for all parts of the mesh with **Orient all parts in the same way**. > [!WARNING] > ### Notes > > In case of a CAD compound, you obtain a single mesh composed of different sub meshes (compound). Each CAD surface of the compound is transformed in one independent piece in the mesh. > [!TIP] > ### Tips & Tricks > > It is recommended to use the **Current deflection** as it does not require to compute a new discrete representation from the current one. > > If you need a new discrete representation, it is recommended to use an **Adaptive deflection** as it requires less computational effort for an equivalent or better quality than an absolute deflection.
