A new curve composed of a sort of middle points x,y,z between 2 other points selected from 2 original curves...

“””””” perhaps the sketch tool can be made to automatically connect lines existing curves to newly drawn ones ?”””””

Yes! The sketch tool makes such beautiful curves but connecting abilities are manual.

If it could be made to have an “endpoint snap” toggle that would keep tangency to curves endpoint snapped onto then continue with its normal behavior, it would be a MONSTER tool!!!

The auto blending/connecting command doesn't exist. One was created that connects “points” within given tolerances. Maybe someone can look at that to see if it can be made to do “endpoints” instead, then do a polylime connection, or a blend….

“Polylime” is a drink sold on the beach in the Caribbean!

Be responsible!

Well, now I am curiuous - of both the UX you are describing, and the Caribbean drink :D

In the meantime I'll keep digging for older threads about line cleanup.

Hi pior, one possibility for a more "construction" oriented way than point manipulation is to use Edit > Trim to open up a gap between piece and then Construct > Blend to put in a smooth blend curve to connect between the pieces.

Hi Burr,

re:
> If it could be made to have an “endpoint snap” toggle <....>

I've tried that before long ago but it doesn't work very well to have one point suddenly shift from the rest, it makes for a noticeable shaping change in the sketch curve right at that spot.

One kind of vague idea that I haven't been able to explore so far is something like a curve airbrush sketcher where you could lay down multiple strokes and also erase areas and make a smooth curve fit through the densest zone.

That would be an incredible addition! And the pen tablet artist will be dancing in the streets and drinking Polylime!

Since the point picker has a radius, can it be scripted or commanded to do a “gap” in a single click?

So like on curves, if you placed a circle of a particular radius and boolean diffed it away from the curve. (The trim and delete part)

The UI could just be a radius/diameter value. It doesn't even need to be joined curves or connected segments. Just delete everything in the radius. (And of course limit the target if something is “selected”….

Brainstorming….. its a dark, grey storm….

Hi Burr,

re:

Maybe like this attached script?

- Michael

BAMMM!!! POW!!! ZAP!!!!

Holy Smokes Batman. Exactly like that!!!

You have made my month. Again!
Thanks.....

I'm glad you like it Burr! :)

I need to make a couple of new options on the pointpicker to enable erasing by holding down the mouse button and dragging instead of only with individual clicks.

- Michael

That will be pretty radical too.

The "single click" mode is still very good for Precision work, so keeping that separate is good. Like "Shakey hands" or moving "Too quickly" may erase more that "1 inch radius"?

as long as single click can differentiate from "Moved a little"....

I had some fun using the "eraser" script.
It seems to work in 3 different irregular ways.

It makes round holes in surfaces, or solids, in one view.

Sometimes the curve needs to be closed and selected, but sometimes it works on an open curve, selected or not selected, or else "calculation fails".

For some curves it leaves behind a partial circular arc, sometimes a gap.

The descriptions swiss cheese and nibbler come to mind...

“””””” Sometimes the curve needs to be closed and selected, but sometimes it works on an open curve, selected or not selected, or else "calculation fails".

Sounds like projection errors with the setup of the curves….

3d curves? Normal trims and booleans can do that when z values (or depth values) are introduced to the projection.

Can you make a file that does this?

Hi Brian, yes it's mostly meant to be used on open curves. With closed curves or solids it is more of a swiss cheese effect.

There really isn't a whole lot to it, it's just doing boolean difference with a circle as the cutting object. On an open curve just pieces of the curve are removed while on a closed curve or solid pieces of the cutting object are part of the result.

> but sometimes it works on an open curve, selected or not selected, or else "calculation fails"

The "Calculation failed" will happen if any of the candidate target curves are not on the same plane as the circle. if you run into this then select some curves that will be on the same plane as the circle so it only tries to target those.

Maybe it would be better if it automatically skipped over curves that are not on the same plane as the circle.

Oh wow indeed ! This is so simple yet so useful. Thank you to all 3 for the suggestions, and of course for the Eraser script ! And I dont think I ever used the Blend command before, so thank you for bringing it up too.

All this may seem a bit tedious on the footage below but this is really useful. In my case it doesn't even need to be applied to the whole drawing, as only the most shaky and disconnected curves need correction (since the image is then rendered as raster pixels for coloring, and the rastering blends the lines that are already near tangent)

There is some slowdown when invoking it without making a selection beforehand, but that's to be expected.
I can't wait to try it while drawing, as opposed to doing it after the fact.

Perhaps ultimately the two operations (eraser then blend) could be rolled into one ?
I also wish Blend had the option to automatically merge the resulting 3 curves.

Enlightening video i was perplex of what Eraser supposed to do!

Curious that was not yet existing! :)

So... ) Sorry in French but...
No need to show Points as shown in the video following!
You can click anywhere in the 3D Space!!!
And in any view!!!

Will be fine if the actual "Circle" eraser can be any form!



So...when you see the vertical "Circle eraser" it's because i click in another view than the 3D one! :)

A temporary French one! ;)
Before without doubt some improvements fonctions of the Command!
https://moiscript.weebly.com/eraser.html

A terrific universal tool!
Waiting the use of any form as actual "circular" !

With curves! :)
