Hmmm...not sure what you mean, but I do feel a certain cynic touch there?! ...clothing patterns really, really do not need a grid. It's virtually the opposite, because a grid would be very much in the way.
When we decide to make an "illustration" version, then things such as grids and perspective guides and all that jazz will get really interesting. But it would be a "design package".

No sacarms from me!
It's just i am a little free on space when there is no orign, axis...and grid

Awww...I made a little video for you, but the quality is so miserable and the forum doesn't play it. I still have to figure this out!
But here's a snapshot of the end:

I believe i understand your grid trick!

Else i use this free cool horst for images : https://imgbox.com I don't know their business plane ... i don't see publicity...

Why there is no DXF Import ?

Imports will come next... but first SVG correctly

Always some problems with SVG to Rabbit from my side!
And you don't want use PDF as "support of Beziers curve" for importation inside the White Rabbit ?
A little star (PDF) for test...

I use this trio Affinity Designer, Moi3D, Inkscape for all vectorial things and WhiteRabbit for torture it!
(Bezier curves etc...absolutly no problem between them with the PDF (1.4, 1.5)

Yeah, I'm inching my way toward vector pdf. It's terribly documented...like almost not at all and I have to figure out how to do this in JavaFX of all languages. Quite nightmarish. But I will solve it.

Updated 1.047, 1.048 along the world!
