Barley Twist Spirals
-
-
This thread is hot! Another point I would make is with screw.rb one can then make a component of spiral section that would stack directly beneath the other (without turning) and so you could increase, vary the height (within a module) easily.
I assume that can be done with Gilles' version.

Yes we can!
huhu couldn't resist.

If I understand you right this is one method I used - I made a 2 1/2" profile (the profile of my barley twist router cutter) then used the screw plugin to make a 5" high one revolution spiral. I grouped it, then copied and stacked it on top the other spiral. I then selected those to array the rest of the way.

That's pretty much it but use a component instead of a group.

Still not sure why there is such a difference in file size -
I believe it's quasi the same size maybe a little less for the group because there is less informations inside no Glue etc..., but same info as pure geometry.

Here is your model with some corrections and the use of components,note it is 650Kb instead of 1950.Isn't it a big difference?
Also modifying all instances at once.
Create libraries for further use in other models. -
Re: file size of my barley twist stair newel
I'm still perplexed by the size of my file. I started over with a new SU file and made my newel without the barley twist. After imported my profile from CAD, did a sweep, created a component of the newel and my file size is 3 MB. What gives?
BTW I have purged layers from the CAD file import -
How many segments did your imported profile turn out to have? The profile I created last night with the Bezier tool had 22 (including the two little short segments I added at the ends. And the total number of entities after one turn of the screw was 2686.

How can I determine that?
Also I made another barley twist profile, ran the screw plugin and rotated like you did (7 1/2d for 24 seg.). I could not grab the edge of the component for copying and moving. Why did it work for you? -

How can I determine that?Select the imported profile and look at the entity count in Window>Model Info. Repeat that for the entire selected twist.

Did you hide the edges before trying to copy? If so, turn on Hidden Geometry (View menu) or do as I did and wait until after copying the component before hiding the edges.
-
also, time to time go window/ model info/statistics/purge unused.

Any thing interesting here: This is my swept newel no twist yet
-
That's not overly useful by itself but I expect it'll result in a fairly large file size by itself. Is that for the entire newel post sans twist? You could actually make the newel post as a half or quarter, make that a component and copy rotate it as I showed you the other night.

That is the newel without the twist.
I could make the newel as you say but that doesn't account for how gilles could take my existing file and reduce it to such a small size. I'm missing something. -
It is the interest with components.
In my file the newel with the twist is about 690Kb, duplicate X100 it is only 1178KB...
Imagine 690X100. -

Imagine 690X100.Pulling my last bit of hair out - The uploaded file is 2.4 MB. How can I reduce the the size of the file? It is already composed of components. How did you take my large file last time and get it to less than 1 MB

Here are some barley twists I made for the base of an altar for a church in Texas. They were machined on a CNC. The model started in Sketchup but I had to go to Rhino to tweak the legs.
About 25 hours each for cutting, matching and gluing, plus 30 hours milling and 30 hours of sanding. The plates at top & bottom were hand turned. Both the spiral and the worm diameter taper. The gullet follows along a different taper.
I have more photos of the set at http://www.SpringwoodStudios.com It's the first time I've done a whole church in SU. Thanks to all on the forum who helped with the tricky bits
