# In-house Extensions # Modify Path # To Absolute This extension simply transform paths from relative coordinates to absolute coordinate. The path's "d" attribute will be reconfigured to get uppercase command letters like A C M Z V H L instead of a c m z v h l. # Perspective ## Example with text ### Write some text and convert Object to Path [![grafik.png](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/scaled-1680-/Rw2Hs8MphBtmym0u-grafik.png)](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/Rw2Hs8MphBtmym0u-grafik.png) ### Ungroup [![grafik.png](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/scaled-1680-/kQdM9eDeWOe0840Q-grafik.png)](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/kQdM9eDeWOe0840Q-grafik.png) ## Combine to one Path [![grafik.png](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/scaled-1680-/knEFyMeANDiWywW7-grafik.png)](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/knEFyMeANDiWywW7-grafik.png) ### Draw a border path [![grafik.png](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/scaled-1680-/UE9DbSL9AZReRpZF-grafik.png)](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/UE9DbSL9AZReRpZF-grafik.png) ### "Modify Path → Perspective" Select the text first, then the border.

This effect can also be done with Live Path Effect or with other extensions - see [Transformations](https://wiki.stadtfabrikanten.org/books/fablab-chemnitz/chapter/transformations "Transformations")

# Convert to Dashes This extension can be used to create bridges / tabs for a laser cutter job. We can define a custom line style (dashed) and convert it using this extension.

In the example line length is 168.71 mm. If we want a single 2 mm gap we set stroke dash array to 168.71mm - 2mm = 166.71mm [![grafik.png](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/scaled-1680-/OdrtkbmLJ8jZtFzz-grafik.png)](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/OdrtkbmLJ8jZtFzz-grafik.png) [![grafik.png](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/scaled-1680-/Eu7Yty0PP5b4O4B0-grafik.png)](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/Eu7Yty0PP5b4O4B0-grafik.png) If we want three gaps in a path with length of 168.71 mm and a gap length of 2 mm we set the stroke-dasharray to: 80.355 2.0 → because 3 \* 80.355 mm + 2 \* 2.0 mm = 168.71 mm [![grafik.png](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/scaled-1680-/BRPwBg7XO304cA3G-grafik.png)](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/BRPwBg7XO304cA3G-grafik.png) If we want three gaps in a path with length of 168.71 mm and a gap length of 2 mm we set the stroke-dasharray to: 50.236 2.0 → because 3 \* 50.236 mm + 3 \* 2.0 mm = 168.71 mm [![grafik.png](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/scaled-1680-/AUE6v1gaCIJ0xG20-grafik.png)](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/AUE6v1gaCIJ0xG20-grafik.png) # Run the "Convert to Dashes" extension # Add Nodes This behaves similar like [Split Bezier (Subdivide Path)](https://wiki.stadtfabrikanten.org/books/fablab-chemnitz/page/split-bezier-subdivide-path) ## Draw some path [![grafik.png](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/scaled-1680-/doZhDD6aWkx3c9d4-grafik.png)](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/doZhDD6aWkx3c9d4-grafik.png) ## Run "Modify Path" → "Add Nodes" [![grafik.png](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/scaled-1680-/QViUqaHY5r6v0fyn-grafik.png)](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/QViUqaHY5r6v0fyn-grafik.png) # Approximate Curves by Straight Lines (Flatten Beziers) Hint: The new name of this extension is "Approximate Curves by Straight Lines". The old one was "Flatten Beziers" This plugin does not apply for paths in groups. Please ungroup before. You can use Extensions → Arrange → Deep Ungroup) or [Ungrouper And Element Migrator/Filter](https://wiki.stadtfabrikanten.org/books/fablab-chemnitz/page/ungrouper-and-element-migratorfilter). This extension is similar to [Convert To Polylines](https://wiki.stadtfabrikanten.org/books/inventar-und-handbucher/page/migration-from-h2-to-postgresql) but has more control over the contours. ## Draw some path [![grafik.png](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/scaled-1680-/zLTpp613zIWJyJQH-grafik.png)](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/zLTpp613zIWJyJQH-grafik.png) ## Run the extension ![(Info)](https://old.stadtfabrikanten.org/s/-6fzg5h/9012/tu5x00/_/images/icons/emoticons/information.svg) The higher the flatness value the less grade of detail the new polyline will have. [![grafik.png](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/scaled-1680-/QJYdf8h1CWrWnePw-grafik.png)](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/QJYdf8h1CWrWnePw-grafik.png) ## Get the result Depending on the flatness we can get really smooth or really rough edges! Smooth paths have a lot more handles (points)! [![grafik.png](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/scaled-1680-/BWcpp5g9QRikxIje-grafik.png)](https://wiki.stadtfabrikanten.org/uploads/images/gallery/2025-05/BWcpp5g9QRikxIje-grafik.png)

Similar behaviour to flatten a curve can be forced by switching from to line type to curve type, but with less control for smoothness / segmentation.
