When designing large projects you may encounter speed problems in modeling. You can adjust the graphics settings to speed up modeling. Below is an example of optimal graphics settings for large projects.
Select> Preferences > Graphics.
Try the following settings:
Defines the transparency of a part selected in the model. Does not affect the model rotation.
When set to zero, the edge lines in the model are rough. This is favorable in terms of rotation.
If the model includes point clouds, this setting reduces the number of points and thus lightens the model in rotation.
When not selected, the model edge lines are not drawn when the model is stationary, or when the model is rotated, panned or zoomed. The model is drawn faster when the motion stops.
When selected, the material textures are shown in the OpenGL shaded model. Clearing the check box reduces visible details and speeds up refreshing the screen.
Effective when the model is limited with planar faces. When cleared, the cross sections are drawn in the limited 3D model. Does not affect the model rotation.
When selected, the reference geometry is drawn in gray. The geometry to be edited is shown in true colors. When cleared, rotating the model is slightly faster.
Affects the appearance of the shadows and the reflection of the lights. Clearing the check box speeds up refreshing the screen.
Defines the drawing threshold for an object in pixels. Small objects are hidden which reduces the details to be drawn when rotating a large model.
Defines the lightened representation threshold for an object in pixels.
For static view: When the model is zoomed out, the objects that are zoomed smaller than the threshold are changed to a lightened point mesh. Do not use large values here (>500). Large values slow down loading the model.
When rotating model: The greater the value (for example 20000), the faster the rotation of the model. But then fewer objects are visible during the rotation.
