(SOLVED) Creating a curve on a face

Support Modeling
#1

Is there a way to create a Bezier type curve on a face in Blender so that you can extrude the resulting faces?

See uploaded image as an example.

I had to use Illustrator and a Blender screenshot to compose the image.

Thank you.

you can give the curve an extrusion value in the curve settings, and you can also convert it to a mesh with alt-C then extrude the mesh normally.

Thank you modron.

I know how to extrude the resulting face but it is the creating a curve to start with on a face that I am stuck on.

The knife tool cuts nice straight lines across from one edge to another but i don’t see where I can add a curve to a face.

try using the knife project tool to project the curves contours as a cut onto the mesh

Try this to get nice curved cuts :

  • Add a Plane

  • Go to Edit Mode , select the whole plane and press W -> Subdivide

  • Go to Object mode, with the plane object selected enable Wire and Display all Wire in the Object panel

  • Add a Curve object and move the curve to some distance above the plane

  • Go to Edit mode and edit the curve the way you want from the Top view

  • Go to Edit Mode and set yourself to the Top View and press A to have the whole plane selected

  • On the Toolshelf (panel to the left of the 3D view) click on the “Knife Project” button

You can then dissolve the faces you don’t need to keep only the curved cut you want

Knife project perhaps. http://www.pasteall.org/pic/show.php?id=49465
Select curve, select mesh, edit mode, position your view to the cut direction and press knife project on the tool shelf.

Edit: as in Sanctuary’s post…
Edit 2: the heck. One post late I would understand but two… I’ll blame the forum for that.

Thank you Small Troll. I just tried it and it worked. :slight_smile:

I was hoping i could draw a curve directly onto the face but maybe that will be for a future release. :slight_smile:

Thank you Sanctuary for all the time and effort you took to reply. I just tried the Knife projection and it worked a treat. :slight_smile:

JA12 Thank you anyway. Much appreciated.

@JA12: Happens all the time… I’d say provs use to cache things.

As a proof of knife tool:
