Does anyone know how the knife project tool works in blender 2.69?
The way it is discirbed on the wikipage
http://wiki.blender.org/index.php/Doc:2.6/Manual/Modeling/Meshes/Editing/Subdividing/Knife_Subdivide
doesn’t work…
Many Thanks!
It works for me following the process described in the wiki. I suggest you read again and follow exactly what it says.
Select the object you want to use to cut, shift select the object you want to cut so both are selected, then go into edit mode and press the Knife Project button or press Spacebar and search for Knife, select Knife Project. Done.
Works for me with 2.69. I’ve noticed that it sometimes misses cuts for parts of the mesh that are close to coplanar with the target. My workaround was to move the meshes apart a little.
Works for me too.
There was a bug in which the project knife missed some cuts on some (even simple) geometry, the problem was linked to the knife code itself and was fixed a few days after the 2.69 release.
So to benefit from those fixes you will need to use a more advanced (and potentially less stable) version from the buildbot or graphicall as the stable current release unfortunately does still have the bugs
I figure out what it does. It projects the object in line with your view to the other object, I thought it would be projected according to an axis.
Thanks guys.
I am trying to use Knife Project , but it is showing error 00AB39 “No other selected objects found to use for projection”, thought, i did exactly as the wiki said.
Subdivided the cube 5 times. Added a Sphere. First selected the sphere , then Cube in object mode. switched to edit and pressed Knife Project.
I haven’t used this before, so i am bit puzzled about the usage.
I am using official 2.69.
Guess you need something flat instead of the sphere. Too thick knife, doesn’t cut well ;). Try circle aligned to view instead.
Try this: go to edit mode, then Ctrl-select the object you want to do the cutting. Then hit Knife Project. And yes, I think you need an open mesh, like an unfilled circle as the knife object.
Yes, i remember it was discussed somewhere in the general board, apparently the Knife Project can’t work when the object being used for the projection is a closed mesh.
So it would work with a circle, but not with a sphere
Thanx. It worked. They should’ve mentioned it in the wiki.
I tried for hours and it did not work. I found out, that the object that will be cut, must be completely visible on the viewport. If parts of it are off the screen, it will not be cut.
I just cant it to work in 2.70 on mac. I find the booltools much nicer to work with by the way, way more control and you can preview it sort of better
This tool is great , but I am not sure how to make the newly created edges to be selected , sometimes it is done, and another times it is not.
Is there a way to get the projected knife to cut through the entire mesh instead of just the visible ones? For example, using a plane as a cutter, and a cube to be cut, when looking at the top of the cube and pressing the knife project, only the top face of the cube would get cut.
Look at the status line below when hit K. Z key is cut through.
That’s just for the regular knife tool. I did see that I could use the F6 panel for a cut through option. Thanks for your response.
Ops - toolshelf or F6 - check Cut trough.
Yup, I saw that it was at the bottom of the tool shelf as well after I posted. Thanks for adding that point to this discussion so others would see it.
I ran into this problem today while following the “Wall of Mailboxes” tutorial on cgcookie. I’m on a Mac, latest build of 2.71. The solution was to delete the back vertices of the “cutting” object so that it was a single set of coplanar faces. It worked fine once I did that. Kinda smells like a bug, but it seems like a newish feature. Cheers!
