Rhinoceros (About unrolling commands)

[honer827]

Hi everyone;

I am trying to nest a sailing boat's deck plates and shell expansion plates. There is non-developable plates (curves in 3 dimensions) So which command is more useful than other? I guess there is three options : Unroll, Smash and squish ?

[honer827]

material of sailing boat is aluminium.

Squish http://docs.mcneel.com/rhino/5/help/...nds/squish.htm

UnRollSrf http://docs.mcneel.com/rhino/5/help/.../unrollsrf.htm

Smash http://docs.mcneel.com/rhino/5/help/...ands/smash.htm

McNeel recommends using Squish rather than Smash. Squish is newer and provides more controls including how the surface will distort when it flattens. Also Squish has the associated SquishBack and SquishInfo commands.

From McNeel's website: http://wiki.mcneel.com/labs/advancedflattening

Rhino 4.0 has:

• UnRollSrf - makes a flat pattern from 3-D developable (curved in one direction) surfaces. Always use this command first. If it fails, then try Squish.

• Smash - is a special version of UnRollSrf that does not check to see if the surface is developable. It is not recommended now that Squish is available.

• Squish new - makes a flat pattern from a 3-D non-developable (curved in two directions) surface or polygon mesh. In general, try UnRollSrf first.

Experiment. Try flattening the same surface using the different commands, and different settings within Squish.

Thank you for answer David. In your opininon, which one is more safe while nesting aluminium plates ? I am scaring in case plates wont fit.

[honer827]

This is deck plates of my sailing. And ı squished some plates. Do you think that this is true?

[DCockey]

What method will be used to make the flat plates conform to the compound curvature surface?

[honer827]

ı used "squish" command. Was this answer of your question? Maybe ı underdtand wrong your question.

[DCockey]

When the boat is actually built from aluminum, how will the flat aluminum plates be formed so that they conform to the compound surface?

It should be very simple...
Before "Squishing" just divide the surface according to the plate distribution you want using "Split" command...
Then go for squish....
the plate will be of course fitted nicely... I did it practically by myself...
