How do i add thickness to a polyline in Rhinoceros 3D

Small

hi Mark Goody,
following picture can guide you to add thickness to any curves
by adding few simple steps while modelling.

  1. Step 1:

    Draw curves and type ( in command Bar ) or click on "options" icon

  2. Step 2:

    In rhino options click " Appearance "

  3. Step 3:

    As soon as you click " Appearance " a drop down pop up will open
    as " Advance setting "

  4. Step 4:

    Click in the " Advance setting " button , you will see " Advance Display setting "and then click on any viewport names ,
    in this tutorial I have used wireframe .

  5. Step 5:

    At the bottom of the pop out menu ( Rhino options ) you will find a copy button,
    this button will make a duplicate copy of the selected viewport. Thus as soon as you hit the button ..

  6. Step 6:

    immediately a " Display mode options " window will open, that says " copy of wireframe"

  7. Step 7:

    Now under " copy of wireframe" we can see " -objects " which is further
    having settings for various objects namely ; points, curves, surfaces and meshes . As we need to add width thickness on the curves ( polylines, ect)
    click on curves button/ tab , upon that you will see " Curve width pixels "

  8. Step 8:

    edit that column as per your requirement ( I have edited it to 5 pixels ).
    than press/ click " ok "
    ( the settings gets saved)

  9. Step 9:

    Now select the curve you want to add thickness to ( I have selected a circle )

  10. Step 10:

    now in command bar type ( keep curve selected )
    " setobjectdisplaymode "
    and press enter key

  11. Step 11:

    Choose attribute for selected object
    ( the selected curves will show the changes only in the active view , i.e in the view in which it is displayed )
    click on " mode "
    or type " M " in key board and press the space key

  12. Step 12:

    ON clicking that you will see all the viewports including " copy of wireframe " ( which we recently created. Choose " copy of wireframe "

  13. Step 13:

    As soon as you click on the " copy of wireframe "
    the command gets over and you find that the curve which is selected have a
    different width thickness than other curves. This change in display can be
    reversed by same method
    ( just click on " user view " in choosing attributes )

  14. Step 14:

    Enlarge the veiwport and inspect, this will not change its apperence in other viewports , you will have repeat same steps in different veiwports in order to see the effect

  15. Step 15:

    Now if you want to see the similar kind of effect in you prints also than he
    under object properties

  16. Step 16:

    There is print width option in the bottom of the op out menu.
    by default its layers , so click on that and..

  17. Step 17:

    edit the value

  18. Step 18:

    Than go to print command

  19. Step 19:

    As soon as you execute the command you can see the
    curve in different width in the print preview.

  20. Step 20:

    I hope this is helpful :)
