Import a 2D File into a 3D Sketch Takes Time

You can import 2D draw files (DXF, DWG, EXB) into a 3D scene.

Method 1: Use [Import Reference 2D] command in the [Tools] tab.

Method 2: In Sketch Edit mode, right-click → select [Import]

This function is useful for converting 2D drawings into 3D, or for comparing an existing 2D assembly drawing with a newly modified 3D model.

However, import time can become significantly longer in some cases.

Causes:

The 2D drawing contains many unnecessary elements:
e.g., centerlines, borders, title blocks, text, dimensions.
The drawing uses many layers.
The file is a large-scale assembly or contains a high number of lines.

Solutions:

1. Delete Unnecessary Lines/Elements in CAXA Draft

For example, you can bulk-delete centerlines using Quick Select.

[1] Click [Quick Select] at the top of the Properties pane.

[2] Choose the unwanted linetype and click [OK].

Delete the [Delete] key.

※ [Quick Selection] You can also choose from other colors and line thickness.

2. Merge Layers into a Single Layer

during import.

[1] In CAXA Draft, select all objects (Ctrl + A)

[2] Click [Layer] in the [Common] tab.

Select a single target layer for all selected objects.

3. Remove Unused Layers

You can use the [Purge] command to delete unnecessary layers in bulk.

[1] While no command is active, type "Purge" (the input appears at the bottom right of the screen).

The Purge window opens.

[2] Check [Show objects that can be purged] and click [Delete All].

4. Separate Projection Views into Individual Files

[1] In CAXA Draft, save each projection view (front, side, top, etc.) into separate files.
ex) Create Front View.dxf and Bottom view.dxf, then each import into 3D sketch.

[2] Import each file individually into the 3D scene.

※This can reduce and distribute data load, resulting in faster import times.
