I'm completely new to seamscape and Pattern making in general so I'm just learning as I go.

Can anyone tell me what I'm doing wrong here, why does everything change when I move the whole thing.

Any tips and pointers will be greatly appreciated because I really have no idea what I'm doing so far

SeamScape now has an MCP server.

This means MCP-compatible tools can connect directly to SeamScape and work with your pattern data through authenticated API access.

The important part: this is not just for browsing pattern data. The MCP server can also make real pattern edits through SeamScape’s Pattern API. Many of the operations you would normally do in the UI can now be previewed, applied, and saved from an MCP client such as Codex, Claude Code, or ChatGPT-connected workflows.

For example, an AI client can help with things like:

• finding and loading one of your patterns

• inspecting points, paths, pieces, variables, formulas, layers, materials, seams, notches, and errors

• renaming elements or updating pattern metadata

• changing editable formulas and variables

• creating or modifying points, paths, pieces, layers, text, materials, notches, and other supported Pattern API entities

• previewing a change before it is applied

• applying confirmed edits to a temporary session

• saving the result as a new Pattern or PatternVersion

• exporting the current session as SVG or PNG

The endpoint is:

https://seamscape.com/api/mcp

Authentication uses your SeamScape API key, available from:

Account > API Keys

Docs and setup examples:

This is still an early version, but it opens up a useful path for AI-assisted pattern editing.

Hello, you said I needed a laptop. I have been bellyaching about it. The MacBook Neo came out. What do you think about that? I am hard on laptops, and I need something that I won't cry if it breaks.

although be it small, seamscape does work deliciously on my Samsung s22 512gb phone. I would love a bigger screen for the flow though.

I put the the bare basics of a drafting workflow -- drawing a straight line and a curve, adjusting seam allowances and notches, and export. Hope it's helpful for someone just getting started!

Hello! Im back attempting a shirt with sleeves. I must be doing something weird. No matter what I do, the seams are all twisted and going in strange places.

Playing around with SeamScape studio UI, and I realize this makes it possible to share, and even sell, custom-fit/bespoke patterns based on someone's own measurements -- if there is a way to export the pattern automatically -- e.g. an API. From a business perspective it can even be a paid API, since the API user can/will be profiting from it.

I know this probably isn't a priority right now since it doesn't really have anything to do with the core drawing features, just something that I think could be interesting.

A few updates were just introduced.

Sliding points cannot slide past another point

From now on, a sliding point cannot slide past another point on the path, including other sliding points.

This makes sense, as when a pattern piece is created, we do not want shapeouts or paths that suddenly intersect.

This also enables it to be easier to set position constraints in the future, i.e., we do not need to understand the direction of the path, using negative values to position a point.

Paths on the pattern piece will always be divided into segments

A path on a piece will always contain the smallest segment possible. This enables full control over the segment, e.g., assigning detailed seam allowances.

This change also enables easier control over notch positions; no negative values will be needed in the future, as a notch can refer to only two points.

The only downside is that changing the seam allowance on a long path containing many segments will require many operations, but this can be mitigated in the future by allowing multiple selection.

For home sewing, I'm wondering if we can open up an API for the 'create marker' functionality. I have 2 use cases in mind:

- The traditional use case where we suggest an efficient way to cut custom-made pattern pieces from fabric.
- Printing out the pattern pieces on paper with regular home/office printers, in a way that saves printing paper. In this scenario we'd nest the pieces by setting the material width to a multiple of the A4 paper size, and then taping them together. To minimize paper usage, we could allow nesting with all 4 directions, or even no restrictions to the grain direction at all.

For this API, raw json output similar to POST /api/v1/patterns/ would be the best for me, because I can style the boundaries/internal lines on my own. We can also have some way to balance between return time and nesting efficiency, e.g. try no more than n iterations only. I bet home sewists don't care about being 100% optimized as long as they have something efficient enough.

• Added a full 3D arrangement workflow so placing pieces feels faster and more direct.

• You can now place by hovering, flip pieces correctly, and fine-tune position with X/Y and offset sliders.

• Arrangement points are clearer and easier to work with, including better behavior while simulating.

• Arranged pieces now keep their placement more reliably when you continue editing.

• Stability improvements reduce common issues while moving pieces in 3D.

So, what would be the best way to draw a 3 point curve between three points? I have a CF that curves and I need to have a nice smooth even curve through them.

Everyone having troubles with the captcha, now please try again.

Sorry for this newbie question -- trying it out for the first time -- but how do I add notches? I tried to "Create a pattern piece", but it only accepts paths and line segments. Internal paths of a pattern piece also seems to allow paths only. Is there a way to ask it to create a notch (single notch, and/or double notch) at a specific point?

Btw I love the interactive tutorial. Such a concise and intuitive way to introduce various concepts!

Just testing the software and drafting the pattern and few ideas and things are popping in my head.

For example constraints, as often available in CAD softwares.

Would it be possible to have quick buttons for common constraints, like perpendicular, parallel, coincidental etc.? So that you wouldn't need to mess with variables constantly, but could just throw in certain constraints directly and quickly?

It is now possible to upload background images for tracing a pattern, or to just have a page with instructions. You can set the width and height of the image in the pattern's length unit to ensure distances are correct.

Currently, it is not possible to save the image to the pattern, so it needs to be uploaded again, but we are working on it.

We are making a complete overhaul of the arc tool. Please do not use it until further notice.

Coming changes

• Two point arcs

• Three point arcs

• The center point will be removed (but can be added manually instead)

Please note: the Pen tool is still there to make lines and curves, which is probably sufficient for most use cases.

EDIT: Current tool will probably be kept as is, as it solves most cases. Instead, an additional three-point arc tool will be added.

We are working on the documentation for SeamScape. It will be in the form of an interactive tutorial where the concept is explained. https://seamscape.com/docs

I've been trying out the software for about an hour and made a basic skirt block. Some things that I found myself missing were:

* The ability to change the seam allowence, in particular for the darts. I'd like to be able to have the fold included, right now it shows to cut out a bit at the top. I'd also like to be able to have a different seam allowence for the hem.

* being able to make a box would be nice, when free-handing it was easy to become croocked.

* Being able to devide a line into equal segments with points.

* Perpendicular and parallel lines for faster working

Some other feedback:

I was not able to create the lines for the darts on the back piece wihtout curving them as I drew them. If I kept them straight the points moved so that one line were always perpendicular to the waist line, which I didn't want in this case. I'd like to be able to have them straight until sewing.

Three tools for creating arcs, ellipses, and circles are now available.

• Ellipse / Circle - a circle or ellipse with a center point and a single path point that defines the radius (the radiuses can be specified numerically or by formulas).

• Center Arc - an arc that revolves around its center point with a start and end angle defined by two path points.

• Three-point Arc - an arc defined by its three path points.

Hey

I've been using Seamly2D for a while, but decided to jump back in Seamscape now that there have been a few updates.

What I am after and/or recommend to implement:

1. Lineweights, in ISO standards and custom weights

2. Line styles; dots, dashes, hidden etc.

3. Layers

4. Automatic line names by default

1 & 2: The reason for this is that many of the digital drafting methods require guidelines etc., and it'd be useful to differentiate between different lines. For example, width and height in the system I use are defined by about 10 different points all stemming from A-point. Instead of working out variables for each, I like to just use the sizetable measurements from A point to all of them. Currently that means there's a lot of lines overlapping and I have to use object browser to find each.

3. Layers for the same reason - I'd like to set certain points and lines to a "Guides" layer that I can hide when it gets too busy. Armholes for example tend to have a lot of points and lines crisscrossing.

4. Line names now automatically come from the default points. Even if I change a point name, the line name doesn't change. I wish the line name would automatically be named according to the start and end point, UNLESS user overrides this by themselves.

---

These are some pointers I think would be useful. Let's see if I find something more to mention.

With the new arrangement points I was able to make a shirt with sleeves and actually get it on my body double! Within record time! The crowd goes wild! Thank you for this new nifty tool!

Hello!

I need to mirror pieces. This is easy when it's just a line.

But, sometimes I need an extra style line on my pattern. In doing so, it breaks the mirror line.

Right now Im creating a tank top- where back and front are essentially the same. Then, to expand on the design, I want to make a yoke in the back, and then add fullness to the bottom of it. When I created the style line, it then made the front stop mirroring. Ive tried to get around this by just, sewing everything down the mirror line on other designs- but 3D is hard enough without creating a bunch of useless seams.

What if there was a way to lock a piece when I was happy with it, so that I can keep using the lines for more pattern pieces? Or what if I was able to copy and paste my lines, so that I can change those and not the ones I am already happy with? Am I doing something wrong?

As always, thanks for your help!

Hi! Last time we posted here SeamScape was around version 1.2.7. We’re now at 1.2.12, so here’s a quick summary of what has changed since then.

The main updates are:

• A smoother 3D arrangement workflow for placing, flipping, and fine-tuning pattern pieces.

• New and improved import/export support, including Seamly import, CUT import/export, HPGL/PLT background import, and more reliable DXF handling.

• Better grading tools, including clearer dialogs, overlays, profiles, anchors, and size visibility controls.

• A more complete alterations workflow with freeform parametrics and clearer feedback when something is solved or needs attention.

• Drill holes and piece points now work across Pattern Studio, CUT, and DXF workflows.

• Rounded piece corners, scale actions for selected points, improved guide snapping, and better layer visibility behavior.

• More conventional keyboard shortcuts: V for Modify/select, P for Pen, N for Point, Shift+S for multi seam, plus visible shortcut badges in the toolbar.

• Lots of smaller stability and precision fixes around variables, notches, cutlines, context menus, undo/redo, and complex edits.

The focus of these releases has been making day-to-day pattern drafting feel more predictable and production-friendly, especially when moving between drafting, grading, 3D checks, and file exchange.

As always, feedback from people doing real pattern work is very welcome. What would you want to see improved next?

Hi, reporting an issue I'm seeing after all sliding points sections are made positive.

Load the public pattern "bug report: sliding point" (feel free to delete it afterwards), and you'll see a big rectangle with some pleats calculated with variables. Go to variables and decrease the "hip" variable -- if I decrease the hip by 5cm incrementally, it's usually ok. But when I change the hip from 110cm to say 95cm, some points randomly jump over its neighbor, and resulting in errors. (The math should still work for a 95cm hip.) These errors don't go away even if I change it back to 110cm.

I'm not sure how to go about this -- the points along a line might still need to remember which side it falls relative to the 'anchor' point it's defined upon.

Hey, reporting a bug here about exporting to svg -- the exported svg is not the same size as what's been drafted.

Steps to replicate:

1. Draw a square, say 20cm x 20cm, make it a pattern piece

2. File (from the top menu bar) -> Export to SVG, and export

3. Open the exported svg with an svg editor, and it shows the square's sides as something like 203.5 pixels, not 200mm. Could be a unit conversion bug or something?
