White Rabbit CAD

You don't need to use the Left Button, if you wish to snap, Pilou! Also, if you start not too close to anything and wish only to snap the end, you need not worry either and can start with Right Button, too! ...only in very special and rare cases, where you wish to start without a snap and end with a snap. Even then you can kind of switch and won't need to hold both, but it is a very unusual maneuver, haha!

10:10 sounds like 120 degrees, yes. Just 3rds. If I were to write a full-on CAD software, where everything goes, I would probably have a massive "settings" menu with endless options!

DXF and SVG Export are coming!

I find always the more difficult thing for make something! It's my destiny!

What is radical difference between DXF and SVG for a 2D prog ?

The question of the day : say I draw a line then another one with SHIFT
so they are aligned with 3 vertex points inside (maybe 4 ? )
Does exist a notion of "merging" for have only One line so with just Start & End points ?

[Taron]

DXF is a living, but ancient Vector Graphics format, coming from AutoCAD, I believe.
SVG (scalable vector graphics) is a much younger, more flexible format, used by everything from vector graphics apps to web browsers and comes with scripting within.
But I'm not an expert regarding either, so you may check with WIKI or the likes. I'm sure there are plenty of details to find!

What do you mean by "aligned with 3 vertex points inside"?
If you start a line or bezier, snapped to another tool, it will analyze where you snapped it on and provide a tangent as orientation vector. Holding shift allows you to lock to the tangent or any 90 degree (45 on some) step around it as you change your direction during dragging, while it also offers to lock to compass steps (canvas coordinates).
You may snap to any location on a line, bezier, circle or arc and get the corresponding tangent from that place. If you wish to consider this tangent to have 2 points and then consider your new line (or curve) to start also with 2 points, then you would have 4 points that compute their relationship.

YES, the notion exists to have merge. Not only for lines, but also for patternpiece polygons. It's not possible to merge Beziers, unless I introduce Splines, but I currently don't have that notion, because it is not necessary and only complicates things for no reason. But, yes, merging lines that are in a straight line or polygons that share an edge is definitely on the table!

is definitely on the table!

Yet existing ? if yes what we must do ?
if not ...so wait and see!

Sorry i have forgotten to send image! With image all is more clear in a glance!
2 lines A & B "connected" by the SHIFT alignement
so C yet on the table or out the table? (for the current version that I have)

Oh, yes, yes, I did understand.
It's not in there, yet, but may come.
Whereby, it's not exactly true. In fact, it is already happening, when you do a dart transfer or when you add seam allowance. Both have routines in them, which merge lines that are connected and point into the same direction.

OK possible and very tricky...but It's that I name a little time losing!
I prefer the "may come"

Another thing : when you call the "Move Point" they are lovely orthogonal lines around this special cursor

But as soon as you Click a point for move it they disapears!
Will be more useful if they can existing all the use of the function "Move"!

Oh, we totally did that on purpose, because a pattern gets pretty dense with lines and it could get very confusing during moving. It provides a good orientation around the move action. I could, however, imagine this might make an interesting settings parameter: "Move Point Guides Always On", or so...naming is always challenging.

It's not 2 tiny lines who will make difference on a complex drawing!

So must make some trick for have result searched
Or maybe the 2 crossed infinite lines can snap somewhere and create a temporary invisible line of snaping ? ...
Laborious but possible

Oh, hahaha, you're so inventive, Pilou, so driven to get carried away, hehehe!
This is what happens, when somebody enjoys thinking up problems and drifts off into arbitrary challenges that are of no real-world concern, hehe. Yeah, I like the idea, but that would drive everybody 100% insane, if it was always snapping like that and it would require an elaborate snap-system nobody wishes to learn and soon can only hope enough of the rest of the software is fun enough to ignore it!

But a fun idea!
