Rhino 6 documentation bugs


(Kelvin Cheng) #21

This is correct, just like you can’t snap to control points when they are off. They are not like the insert point of a text or a block that can be snapped to when they are off.

They are the “extrusion points”.


This phantom point is useless - when I try to move it with the gumball, the gumball moves, but the phantom point does not move.


That’s the rotation handle, you should be able to rotate the extrusion around its axis using it. Pulling it along the dotted line direction does nothing - although the Gumball doesn’t really work well with it, it should just either refuse to move, or the handle point should come with it. In any case, I don’t see a whole lot of utility here, but maybe others do.



I believe that this phantom/extrusion point should be used to change diameter of this cylinder.


No, to do that you need to either scale the original profile (if History is on), or sub-object select the upper and lower faces and with the shift key held down, use the gumball “plane” widget to scale 2D the faces in their own planes - drag the widget or type in a scale value.

Fixed in Rhino 6.5, thanks.


Curve piping mesh modifier initially did not support linetypes. In response to my suggestion, McNeal fixed this flaw, and Brian James made a video (Easy stitching with piped linetypes): https://vimeo.com/88067962

Few Rhino users are aware of the fact that curve piping mesh modifier supports linetypes because Rhino documentation does not mention this feature.

@KelvinC FYI

Thank you, @Andrew_Nowicki. I updated the topic with an illustration.

@bobmcneel, thanks for reminding.


Two online Rhino documentation files have wrong links to ExtendDynamic command:

These files link ExtendDynamic command to Extend command.

Actual Rhino documentation file describing the ExtendDynamic command is here:

Extend and ExtendDynamic commands are so similar that they should, in my opinion, be merged into single command

(Kelvin Cheng) #33

Thanks, I’ll take a look.

(Kelvin Cheng) #34

ExtendDynamic was added for some reasons.


Online Rhino documentation file: https://docs.mcneel.com/rhino/6/help/en-us/commands/select-mesh-faces-commands.htm#SelMeshEdges
says: “SelMeshEdges… The command may help if you have a mesh that came from a polysurface but no longer have the polysurface.”

How can a mesh have the polysurface?

(David Cockey) #36

I don’t see anything about the mesh “having” a polysurface. It talks about a mesh which came from a polysurface. The context of the sentence you quoted is an example of where the command may be useful: recovering a polyline approximation of the edges of a polysurface from which a mesh was created.


I have found another bad link in the newinrhino ( https://docs.mcneel.com/rhino/6/help/en-us/commandlist/newinrhino.htm ) file.
SelControlPointRegion link goes to SelPt instead of SelControlPointRegion.

Please replace:

@davidcockey, thanks.

The SelMeshEdges command is basically broken. Added…


(Kelvin Cheng) #39

Fixed. Thank you.

(Kelvin Cheng) #40

Fixed in four pages, thanks.


SetUserText command can attach text key to (mysterious) attributes and objects, but Rhino documentation does not define these (mysterious) attributes.
