I have a simple question about the sweep command. If I select one face and sweep it, it sweeps perp. to the normal "Z" of that face. If I select 2 adjacent faces it sweeps sort of at a 45 to the faces. If I select 3 adjacent faces it sweeps perp to the noral "z" of one that 3 faces. If I select 4 faces it does something totally unrealted to the normal "z" of any of the faces. It actually sweeps in a totally different direction from the others.

See attached image. Is there a way to make the consistent.

Hi fahembree,


The sweep tool in this form (ie tS6.6 form) can't figure out what to do in this situation, as it tries to sweep in different directions at once. This is the "old" tS6.6 sweep tool that is.


The only way to do it would be by a manual process of sweeps with some edge joining and maybe vertex welding afterward. There would be no way to get this version of the sweep tool to recognise what to do in this situation, at least not as far as I am aware.


HTH!

You have to sweep the front and back faces first.

Next, select and sweep the faces on the left and right sides.

I guess it would depend on what you are trying to achieve.
Maybe a checkbox for "per face" would have been handy,
an option to not join vertices,
or have an "extrude" function (as other programs call it) in addition to the sweep.
It is only when verts are shared between selections that it functions in this way (ie seems to get confused about what perpendicular means) and it makes sense because it has to keep the shared edge.
If you scale the swept faces which are selected in your pic # 4 (disable z to avoid making the new faces taller) you will end up with the result on the right. Sweeping each separately gives the result on the left.

Thanks, That indeed works. Simple when you know the solution.
