Methods

LoadCadDocument(CadDocument, bool, int, float, float?, bool, GraphicsContext)

Loads a CAD document asynchronously, processes its entities, and returns a tuple containing a DrawableLineBatch for line rendering and an array of CADText for text entities.

Declaration
public static Task<(DrawableLineBatch, CADText[])> LoadCadDocument(CadDocument cadDocument, bool isDXF, int precision, float maxMTextSize = 0.5, float? customMetersPerUnit = null, bool enableTextRendering = true, GraphicsContext graphicsContext = null)
Parameters
Type Name Description
CadDocument cadDocument

The CAD document to load and process.
bool isDXF

Indicates whether the document is in DXF format.
int precision

The precision to use for polygonal approximations of curves.
float maxMTextSize

The maximum size for MText entities (used for DXF). Default is 0.5f.
float? customMetersPerUnit

The manual scale factor to re-size.
bool enableTextRendering

Indicates whether text rendering is enabled.
GraphicsContext graphicsContext

The graphics context used for rendering operations. If null, the line batch will create it.
Returns
Type Description
Task<(DrawableLineBatch, CADText[])>

A task that represents the asynchronous operation. The task result contains a tuple with:

  • DrawableLineBatch: The batch of drawable lines generated from the CAD entities.
  • CADText[]: An array of CAD text entities extracted from the document.

ProcessEntity(Entity, int, ref DrawableLineBatch, List<CADText>, bool, Insert, Transform, float, bool)

Processes a single CAD entity, converting it into drawable line batches and/or text representations. Handles transformation, color, and layer inheritance, as well as nested inserts and hatches.

Declaration
public static void ProcessEntity(Entity entity, int precision, ref DrawableLineBatch linebatch, List<CADText> texts, bool isDXF, Insert parentInsert = null, Transform parentTransform = null, float maxMTextSize = 0.5, bool enableTextRendering = true)
Parameters
Type Name Description
Entity entity

The CAD entity to process.
int precision

The precision to use for polygonal approximations of curves.
DrawableLineBatch linebatch

Reference to the DrawableLineBatch where lines will be added.
List<CADText> texts

A list to collect CADText objects for text entities.
bool isDXF

Indicates whether the document is in DXF format.
Insert parentInsert

Optional parent ACadSharp.Entities.Insert for nested transformations. Default is null.
Transform parentTransform

Optional parent transformation matrix. Default is null.
float maxMTextSize

The maximum size for MText entities (used for DXF). Default is 0.5f.
bool enableTextRendering

Indicates whether text rendering is enabled.
