[Plugin] Extrude Edges by Loft

altap

This is really GREAT TIG... and BTW, I want to thank every ruby scripts developpers here again, you're making people happy .

On another side while it may be irrelevant in sketchup ?! , what if it was a live loft sort of modifing the profiles( on which the loft volume is created ) and sketchup regenerate automatically the lofted volume. maybe it is too much asked as i'm already very glad to have a loft tool in Sketchup

thanks tig. excellent plugins. actually this set of tools for extrusion is increasingly complete. and further expand the potential of modeling sketchup.

a small observation.

when you select a curve, changes color.
but generates a rare color "Dashedlines" between blue and another color

a question
You can set the number of Segments per Section: independently?
or number of Segments per Section: General.
osea
number of segments between the first and last section selected

The color 'dashing' is interference between the drawn color and the model's edges - it's pretty much unavoidable - the coloring is only intended to help you remember which curves you you have picked in what order - as ROYGBIV are the rainbow's colors...

You can't currently have different segment-numbers in each section, it's based on the one value you give [which initially defaults as the most segmented curve's edge-count]...
It would be possible to have varying segment counts - I suppose that the dialog could have a section-number entry for each segment defaulting to the maximum number of edges in the pair of curves bounding that section of mesh ? OR it could be a maximum count apportioned across the mesh based on some other factor like the numbers of edges in the curve-pairs...

If users would like that I can come up with something ?
Feedback first please...

Thanks, I'll look at your ES lingvo for a future update...

Did you model this car with loft plugin ?

is there any plugins forums that control the start/end point of line?

Hi, TIG:
Attached is a clumsy half carcass of a fish.
Tailfin done with EExR, I believe.
Main body done with EExR too, but with some corrective restretching and knitting.
Head section begun with progressive modeling by copying the curve and Fredoscaling it into place, and then knitting the faces closed.
Last section done with EExLoft. This section shows the distortion/ drift away from the intended ground curve, even though the ground curve was not part of the selection. You might note the lofted mesh sort of makes a shallow sine wave shape above and below the ground face.

Just wondering how you are progressing on the adjustments you are making.

wip for review

TIG

One of the reasons I think you are getting problems is that many faces of the mesh might be getting too small - try modeling the fish x10 real size and scaling the results down later.
SUp has a limit to how small a face it can make but scaling downwards they stay OK...
EEbyLoft does make a bezier transition curve. To control the form better use EEbyRail ?

mitcorb

Thanks, TIG:
As you can easily verify, each long dimension of the faces in the main body is about 30cm. I had the impression that this was sufficient size threshold, considering that the fish it is based on is in reality ~60cm total length. Thank goodness, he is stuffed! Otherwise, measuring him would just add to my misery of this proportional scaling ritual. I couldn't swim that fast, especially with a tape measure in my hand.

TIG

But something ~300mm divides up into many smaller mesh facets and some of these could approach the critical size limit (~1mm) and thereby not get faces etc...

Thanks for amazing new plugins TIG! I have been playing with them for some days now.

Lately I have been trying Extrude Edges by loft, and I thought I did not get the same result every time. I made an experiment: I did the same procedure 12 times in a row using the plugin. I drew one circle along the red axes and copied the circle copying&dragging it upwards the blue axes 3time the radius. Then I used the Extrude Edges by Loft plugin, clicking on the circles in the same order every time. I chose no to all the questions and took every shape as it.

I was hoping to get at straight shape sooner or later and the 12.th time I got the shape I was looking for. Now, is there any type of random function at work here? Is there a way to get the same straight shape every time by modifing the plugin somehow, or even decide how much the shape should twist every time you use the plugin. That would be an awsome feature!

Tx,
Magnar

If you add a small piece of edge off one of the nodes of each of the two the 'circles' then that should 'split' the curves to force a 'start/end' to the two of them - then the EEbyLoft 'twist' will become predictable as it will be made 'End to End'...

magnato

Like this, a simple line between the two circles. Yes, thats works very nice! Thanks a lot!

Or... if you 'angle' the line then the extrusion should 'twist' to match ?
It could also be two separate lines splitting the two loops...

tomot

WOW... a thing of beauty! ...Nice job TIG

I was wondering if its possible to include a Straight line in the "Extrude Edges by Rails" ruby. I have been faking it by drawing a curve with very little radius up to now. Cheers!

magnato

I made some other exaples with five curves. Also in this example it seems to be a good idea to add a line to split the curves to force a 'start/end'. By spliting the curves with a line I found it possible to control the outcome every time. Intersecting the curves with a plane did not have any effect, I had to use a line to get the desired effect. Without splitting the curves the outcome seems to be unpredictabe. Is there a way to add anything to the script of the plugin to split the the curves ?

The form at the left is made with a line to split the curves. The other two are not. To the right the output changed every time even when using the exact same curves.
