Exact projection

 

 

 

This button allows you to turn on the exact projection mode.

This mode is turned off by default, the draft document is therefore a quick projection draft document.

 

Use:

 

Click the icon or select the command View > Exact projection... mode from the drop-down menu.

 

 

Fast projection

(default mode)

The calculation of the projection of the items is based on the 3D visualization of the latter.

The projection time is therefore fast.

Exact projection

The calculation of the projection of the items is based on the 3D geometry of the latter.

The projection time is therefore longer compared to fast mode.

 

 

 

  • If a view is incomplete, change to exact projection mode.

  • When this mode is deactivated (and so using the fast projection), the automatic update is also deactivated.

 

 

 

Additional information:

 

 

With fast projection mode, the view is recalculated with each movement/zoom.

For a draft based on a major 3D geometry , it is therefore advisable to work in exact projection mode. With this mode, even though the projection time is longer, this calculation is only done for the first view. The other views and future displacements/zoom will be immediate.

 

 

Before exporting a draft document, AutoCAD format for example, this must be in exact projection mode.
