+# STL Transformation
+
+OrcaSlicer primarily relies on STL meshes for slicing, but STL files may come with several limitations.
+
+Typically, STL files feature a low polygon count, which can adversely affect print quality.
+In contrast, using STEP files offers a higher-quality mesh that more accurately represents the original design. However, be aware that both high-polygon STL and STEP files can increase slicing time.
+

+
+## Importing STEP files
+
+This setting determines how STEP files are converted into STL files and is displayed during the STEP file import process.  
+If you don't see this when opening a STEP file, check [Don't show again](#Don't-show-again) below.
+
+![image](./images/stl%20transformation/stl-transformation.png)
+
+### Parameters:
+
+The transformation uses [Linear Deflection and Angular Deflection](https://dev.opencascade.org/doc/overview/html/occt_user_guides__mesh.html)  parameters to control the mesh quality.
+A finer mesh will result in a more accurate representation of the original surface, but it will also increase the file size and processing time.
+
+![image](./images/stl%20transformation/stl-transformation-params.png)
+
+ - **Linear Deflection**: Specifies the maximum distance allowed between the original surface and its polygonal approximation. Lower values produce a mesh that more accurately follows the original curvature.
+ - **Angular Deflection**: Defines the maximum allowable angle difference between the actual surface and its tessellated counterpart. Smaller angular deflection values yield a more precise mesh.
+
+#### Split compound and compsolid into multiple objects:
+
+Enabling this option will split the imported 3D file into separate objects. This is especially useful for adjusting individual object positions, tweaking print settings, or optimizing the model through simplification.
+
+![image](./images/stl%20transformation/stl-transformation-split.png)
+
+#### Don't show again
+
+This option will hide the STL transformation dialog when opening a STEP file.
+To restore the dialog, go to "Preferences" (Ctrl + P) > "Show the STEP mesh parameter setting dialog".
+
+![image](./images/stl%20transformation/stl-transformation-enable.png)
+
+## Simplify model
+
+When working with models that have a high polygon count, the Simplify Model option can significantly reduce complexity and help decrease slicing times.
+
+This function is especially useful for improving the performance of the slicer or achieving a specific faceted look for artistic or technical reasons.
+
+To access the Simplify Model option, right-click on the object to simplify in the "Prepare" menu.
+
+![image](./images/stl%20transformation/simplify-menu.png)
+
+It is recommended to enable the "Show Wireframe" option when running a simplification process to visually inspect the outcome. However, be cautious: overly aggressive simplification may lead to noticeable detail loss, increased ringing, or other printing issues.
+
+
+### You can Simplify your model using the following options:
+
+- **Detail Level:** Control the level of detail in the simplified model by choosing from five preset options. This setting allows for a balance between mesh fidelity and performance.
+- **Decimate Ratio:** Adjust the ratio between the original model's polygon count and that of the simplified model. For instance, a decimate ratio of 0.5 will yield a model with approximately half the original number of polygons.
