Navigation:  »No topics above this level« Creating Profile - Projection of Existing Profile on Face or Body

A profile – projection of another 3D profile on a face or body – is created by using the following command option:

         <J>        Construct 3D Profile as projection of 3D Profile to face        

Selection of the body or face on which the original 3D profile will be projected is done by one of the following automenu options provided in this mode:

       <В>        Select Operation        

       <F>        Select face for projecting 3D Profile        

A body or face can be selected in the 3D window by clicking . A body can also be selected in the 3D model tree. The selected body or face is highlighted in the 3D window.

The profile being projected is selected (also directly in the 3D window or in the 3D model tree) using the option:

       <R>        Select 3D Profile to project        

The selection made is sufficient for the profile normal projection. (In this case, the profile creation can be completed by pressing .) In other cases, the projection vector needs to be defined for the original profile by specifying subsequently two 3D points or by selecting one 3D object which is able to define the vector.

To define the vector by two 3D nodes, subsequently use the options:

       <M>        Select first 3D point of projection direction vector        

       <S>        Select second 3D point of projection direction vector        

To select a local coordinate system, the option is provided in the automenu:

       <L>        Select projection direction        

To cancel selection:

       <K>        Cancel selection of projection direction

 

When selecting elements in the described order, the system automatically switches the options for proceeding with the next step. You can do selection in arbitrary order; however, in this case you have to pick the appropriate options manually.
