Registation Marks in Seamly2D Pattern File

Hi all and “Happy Pfingsten / Pentecost“ to all those celebrating …

I am a ‘heathen’ and therefore not bound to religious festivals :thinking: :roll_eyes: .. But, to my query today: ‘Is there a way to include registration marks into a pattern (draft) prior to exporting to .SVG / .PDF?’ The pieces I need to cut are right on the edge of my cutting area : 100 X 57 cm. without being able to relocate the material (and the projected pattern), the piece(s) cannot be cut properly.

I envisage a number - four minimum to maintain orientation - of ‘+’ (crossing lines) at 50 mm intervals. I can create these with the current ‘tool-kit’ but I have no idea how to include these into a ‘New Piece’ from the draft pattern. I can of course use my PDF or vector editing tools, but this entails more workflow steps if / when a Draft is altered and exported. . . Any ideas out there ??

Best regards,

David D.

OK, I think I’ve got it now … Adding internal paths … nice tool!

Any supplementary info / opinions would still be gratefully received.

:hugs:

Not sure if this addresses your issue. You could create a pattern piece without SA, the size of your cutting area… 100 x 57… then in Piece Mode manually place your pattern pieces inside the cutting piece. When you export you will have a bounding box of all the pieces.

Hmm :thinking: … not sure if I understand your drift … can you perhaps clarify? …

Unless you mean that I create a ‘dummy’ piece the size of my cutting mat and then add the actual pieces within the ‘bounding box’ … :thinking:

… my issue was (and has been assigned to the sewing scrap-box anyway) that there was one single piece that was large enough to exceed the cutting area boundary. The correct resolution would be to increase the size of the mat (working on that!) and then the ability to create index / registration markings to re-register the material after moving the projection image.

I’d split the pattern piece into 4 pattern pieces so that you can line them up and use chalk to draw the cut lines on the fabric instead of cutting the fabric directly, so that you can line up each pattern piece perfectly before cutting. However, this may mean that you need to move the projector & re-align it if you don’t want to move the fabric.

This is almost like exporting a full image with the tiled image rectangles shown on top of it.

Maybe we need to add an export option ‘PDF with registration’. I may need to look up better words for this.

The user would enter the width and length of the repeat, and that would define the width and length of the tile on the image.

The registration marks would be “+” cross marks at each tile corner, or line intersection. The tile rectangles wouldn’t be visible, only the “+” cross marks.

We could set the crossmarks to be a black “+” inside a white circle for easy visibility when projecting.

@DavidDeb What do you think?

Thank you @Sue for your comments. Those sound like solid ideas :+1:

Having the ability to set / display, (perhaps user defined?) registration marks at user defined grid resolution / co-ordinates & offsets, would be of great usefulness, especially for those who have made the transition to projection over paper patterns.

I only make the above-mentioned point because I have no deeper attachment to paper patterns, and really begrudge the time spent on doing jig-saw puzzles with A4 / Letter sized pieces. In addition, the correct archiving of paper patterns is way beyond the scope of my hobby room, and my own special brand of what one may generously call “Tidiness” !

PS: If this is seriously meant as an additional feature, please also consider .SVG format too.

I am using projector mostly and even when working and projecting area is 180x100 cm, I almost always move material on the table. My experience:

  • Lines are way better then crosses to match pieces.
  • Certain overlap is needed too. I use 10cm not to lose to much working area, but it would be easier with more.

I am adding one of my working pdfs

Hi @nejcek74 ,

I would be interested in learning of your experiences in ‘projection’, I have just started and use an Epson EB-685W and the < https://www.patternprojector.com > WebApp for the image.

As yet I have not yet really suffered issue with anything nearly as complex and large as your .PDF seems to indicate and I’m keen to learn about this.

Only now I have time to come back to this:

I am using an older Epson projector EH-TW 650, it is fixed on my ceiling:

I am using it through Epson’s native phone app iProjection. Projector is fixed so it is always throwing projection of the same size, in my case 100x180cm, as this is also the width of my table.

  1. I draw pattern in Seamly2D

  1. I export all pattern pieces via “Export pattern pieces” to pdf. Because pdf are working with my CAD program of choice.

  1. I create layouts in CAD Program, Archicad. I am using it because I have a paid licence for it through my job and I am fully versed in it. It could be anything else. Here is my double layout, the coloured part in the middle is presented on Page 1 and Page 2 of pdf for projection. The sides have vertical lines for arranging the fabric (in this case it is 136 cm wide).

  2. I am printing those layouts to final pdf in format 180x100cm. Main point here is I make always full layouts of 180x100 cm, same as it will be later projections. Custom layout and paper format with NO PRINTING MARGINS, PRINT SCALE 1:1 through etc. This is a 30 years old proofed

  3. All my files are synced through the OneDrive, so after making pdf it is very soon (but sadly not instantly) on my phone and I project them. To draw the upper part I move to page 2 and I move the fabric down. Arranging the position is easy, as I have guiding horizontal and vertical lines (yellow one)

My workflow is built on the hardware I have, my software knowledge, and mostly in such a way that I minimised possible errors and I keep full control. I am not sure how many of other people would do the same:

  • my working computer is a desktop workstation
  • projector is connected to phone, as I cannot use it as a network display
  • projector is always in the same spot, but I move the table, and I am using table sides to position it precisely , my “format” or my “working space” is FIXED. I think this point is crucial. It would be even better if that was not my dinning table :slight_smile:
  • I am extremely “fluent” in CAD drawing, but graphic programs like Adobe suit annoys me. I like dxf and I hate svg :smiley:
  • I need clear, fast, repeatable protocols to be efficient and happy with my work.
  • I do know patternprojector project, but I never saw a point of using it, I calibrated the projector directly on it. I also cannot use it for projecting directly from my workstation, as my projector is not in the network.

Thank you, @nejcek74 , for explaining your workflow. It works for you and your garments turn out exactly how you wish them to be. I like that you’ve taken what you have and made it work for you. Well done! :blush:

Hi,

Thanks for the response, very nice setup … something for me to aim at.:+1: :blush:

I assume you meant Adobe suite? I’ve never been a fan of Adobe… especially now that they are all cloud based.

For graphics I’ve always used Corel Draw & Painter. And when it comes to video editing I hate Premier. Like so many Adobe products it’s so unintuitive and bloated. Instead I use Vegas Pro to edit video. The only Adobe application that I’ve used is After Effects only because of the enormous amount of templates out there.

I think we’re all like that. You get use to a workflow that works, and you hate when something changes the flow… like you try to update Windows, and it causes a cascade of issues. Been there. :roll_eyes:
