How to grade a pattern on Seamly2D?


#1

Hey I’m new and have a general understanding on patterns &grading. I’m trying to figure out the best approach to grading on this software as to my understanding it uses formulas? So with my research I haven’t figured out these formulas or where/how to find them. I basically know ex: size 6 graded up to size 8 would be 2 sizes divided proportionality along the certain lines of the pattern etc(simple wording). SO my question is, for grading is it best to have my measurements and find the closest stock measurement provided and tweak it to mine? Would that keep all the necessary formulas intact which would allow me to plug in the new graded sizes I want? If not do I use my own measurement and then create grading formulas or rules? This seems to be just the application I need but just need someone to super simplify the process please!!! Thank you

Just to comment so you can get a better understanding of what I will be trying to accomplish with Seamly2D. I will be created and drafting my patterns in real life for the most part. Which I hope to be able to recreate on this application, and be able to grade them. So my starting point will be an existing pattern that I want to translate and grade and print. I think once I get that base down I will know enough to be able to do other cool things with custom measurements from other people/clients. Thanks

Hi & welcome @Geanbenjamin

Ok… Firstly, Seamly2D doesn’t really ‘Grade’ patterns, rather, it will ‘Resize’ patterns. So you won’t be able to print a pattern with multiple lines all over showing the different sizes of the same pattern. This you will need to export the pattern to .svg and use Inkscape or something to stack them on top of each other. But you can ‘Resize’ patterns simply by changing the measurement file.

You will notice that you have 2 icons on your desktop after installing Seamly2D - one for Seamly2D and the other for SeamlyME.

SeamlyME is where you go to create your measurement files. You can create as many as you wish, for yourself, your customers, friends - these you will create individual measurement files (.vit). You can also create multisize measurement files (.vst) but I’m not going to say much about them. You may download the manuals, read the wiki, etc. on the nitty-gritty, please.

Once you have your measurement file created, then you may close the SeamlyME program and open the Seamly2D program and create a ‘New’ pattern, save it with a name that will make sense to you.

After saving, go ‘File > Measurements > Load Individual’ and select the measurement file you created and then draft your pattern.

At any point, if you wish to load a different set of measurements, just repeat the process of loading a measurement file. If you wish to save the pattern under a different name, the go ‘File > Save as’ and then you can change things in the pattern to suite the new person.

It’s as easy as that. :grin:

You can also use the measurement file repeatedly like this, just saving it in a different name and editing the measurements. This will ensure that you always have all the codes used in the pattern covered in the measurement file.

" After saving, go ‘File > Measurements > Load Individual’ and select the measurement file you created and then draft your pattern."

Hopefully I will get to it today, so essentially it wont automatically grade for me right? I can just plug in the correct average measurements for the next sizes up and down? (and custom measurements etc) I hope I am understanding this right. And thank you for the response Grace!

@Geanbenjamin, I want to add to what Grace said. Please remember that the individual measurements are stored in a separate file. A xxx.vit file contains measurements for one person. A xxx.vst file contains measurements for a range of sizes. So, while she is correct that Seamly2D will not automatically grade the pattern nor will it automatically print multiple sizes on top of one another, it will deal with a range of sizes.

I have a strong personal preference for using only .vit files and having one per individual.

If you are creating a pattern for an unknown group of people who may need different sizes in a range, it may make more sense to use the multisize files.

Yes, I didn’t explain too much about multisizes, although I love to draft with a multisize measurement file loaded, but it’s a whole new conversation and I was quickly replying to you before work. And you also mentioned that you were creating patterns for customers, so I thought to show you that method first.

I’m busy with a blog & videos that may help you a little bit that I still need to add the link to the wiki, but you will find it at http://graces.co.za/index.html. The videos are on the page.

I will be sure to look into all this as well, thank you!
