Scan your sewing patterns with your iPhone or iPad! DartSide is a sewing pattern editor that helps creators with the entire creation process: scanning, construction, industrializing, and exporting. SCAN Scan a paper pattern or a toiling fabric from an image: • Take a photo of a piece of the pattern • Correct the inevitable perspective distortions that come from taking a photo with a camera that isn’t exactly parallel with the pattern • Define the scale of your image • Add the photo to the background of your construction canvas • Lock the image, and use it as a guide to draw the vector contours of your pattern • Hide the image, so that it can be accessed later if you ever want to refer back to it CONSTRUCTION Draw the lines and curves of your patterns using your preferred method: • Draft your pattern from scratch within the app • Adjust a pattern that you’ve scanned from an image • Transform an existing pattern from your project list Key functionality: • Draw and modify lines and curves freely on the screen with your finger or Apple Pencil • Move any point by a specified direction and/or distance • Measure the length between any two points that are linked by a line or curve • Create a trace that can be used to simulate how it mounts with another part of the pattern PIECES You can industrialize all the pieces of your pattern to specify the cutting and the mounting of your model. • Create a new piece by selecting a form you’d like to extract from your construction • Add indicators (notches, markers, fabric grain lines) to each piece • Define seam allowance sizes and corner types EXPORT You can export your patterns in PDF or SVG format. The exported pattern is the exact vector representation you see in Pieces Mode in the app. The exported pattern is compatible with vector drawing apps like Adobe Illustrator or Inkscape. Once exported, you can use one of these tools to finalize the layout and style of your pattern. Project Syncing All your projects are automatically synced to the cloud, no need to remember to manually save to avoid losing your work. The projects are linked to your user account, and can be accessed from multiple devices (iPhone or iPad). Exporting your pattern from DartSide opens up a number of possibilities depending on what other apps you use: • Customize the layout of your pattern • Create a cutting layout to print your pattern on your desired paper size • Make your pattern downloadable on your website or online store ----- Terms of service: https://dartside.app/p/terms/ Privacy policy: https://dartside.app/p/privacy/ We want DartSide to be the best possible partner for all of your pattern drafting needs.

3D data, beautifully and clearly. Kuu3D is a 3D viewer for iPhone and iPad. It supports USDZ, OBJ, STL, glTF / GLB and PLY (point cloud). Open files from the Files app, AirDrop, or the Share sheet of other apps. EASY TO LOOK AT Operate with your fingertips. Rotate with one finger, pan and zoom with two, twist two fingers to tilt, double-tap to show the whole model. Switch between softly shaded MatCap materials to study the form itself. Sky, dusk, night, or sakura: choose a background to suit your mood and your data. Wireframe view to check the flow of the mesh. Drag the circle on screen to change the light direction freely. Change the field of view to adjust perspective. Turntable mode slowly rotates the model so you can take it all in. Grab the toolbar and move it to the top of the screen if you like. HANDY FOR CHECKING See dimensions. The unit is guessed from the file format and can be changed. Get notified when a model's face directions (normals) look reversed. Large files are displayed as smoothly as possible. SIMPLE AND PRIVATE Save your favorite files in the library. No network access. Your files never leave the device, and no personal data is collected. Almost every feature is free. The one-time purchase "Unlock All Features" removes the limits on the turntable (free users get a half turn) and the library size (free users can save 3 files). It is not a subscription. SUPPORTED FORMATS USDZ / USD, OBJ, STL, glTF / GLB, PLY (point cloud) Note: animation playback is not supported.
