Importing/Exporting

インポート / Export Commands

の インポート / 書き出す group lets you move data between SkyCiv CAD and external formats such as images, JSON, PDF, DXF, DWG, セクションビルダー, and S3D.

Use category dropdowns to access related tools for each format.

画像

The Images category provides image import and raster export tools for drawing context and deliverables.

Upload Image (JPG/PNG)

Import a raster image as a reference layer on the canvas

使用する Upload Image to import a JPG or PNG as a background reference. Once placed, the image can be moved, scaled by dragging its corners, or deleted. Multiple images can coexist on the same canvas.

スクリーンショット

[__INSERT_IMAGE__]

Step-by-step

  1. 1クリック Upload Image to open the file picker.
  2. 2Select a JPG or PNG image file.
  3. 3The image appears on canvas – use Move Lines to reposition it and drag a corner point to scale.
💡

ヒント: Large images may slow rendering. Use PNG for transparent overlays and JPG for solid photograph backgrounds. Enable the Snapping Grid to align the image precisely with drawing geometry.

キャンバスを画像として保存

Export the current canvas view as a PNG or JPG image file

キャンバスを画像として保存 takes a snapshot of everything currently visible on the canvas and exports it as a raster image. Choose PNG for high quality with transparency, or JPG for a smaller file size.

スクリーンショット

[__INSERT_IMAGE__]

Step-by-step

  1. 1クリック キャンバスを画像として保存.
  2. 2Select PNG or JPG format in the dialog.
  3. 3Click Save – the image is downloaded to your computer.
💡

ヒント: PNG preserves transparency and produces higher quality output. JPG creates significantly smaller files. The export includes all geometry, 寸法, 画像, and annotations currently visible.

JSON

Upload Canvas from JSON

Restore a previously saved drawing from a JSON file

Upload Canvas from JSON restores a complete drawing from a SkyCiv CAD JSON file, including all geometry, 寸法, annotations, 画像, and settings exactly as they were saved.

スクリーンショット

[__INSERT_IMAGE__]

Step-by-step

  1. 1クリック Upload Canvas from JSON.
  2. 2Select a previously saved JSON drawing file.
  3. 3Drawing content and all settings are fully restored.
💡

ヒント: Loading a JSON file replaces the current canvas. Save your current work first using Save Canvas to JSON before uploading a different file.

Save Canvas to JSON

Export the complete drawing state for backup or sharing

Save Canvas to JSON exports the full drawing as a single JSON file. This is the native SkyCiv CAD format and captures all geometry, 寸法, annotations, 画像, layers, and settings.

スクリーンショット

[__INSERT_IMAGE__]

Step-by-step

  1. 1クリック Save Canvas to JSON.
  2. 2A JSON file containing all drawing data is generated and downloaded.
💡

ヒント: Use JSON saves as your primary backup format. Save versions at key milestones (例えば, before major edits) so you can restore to a known good state if needed.

PDF

Upload PDF File

Import a PDF page as a background reference image

Upload PDF File renders a PDF page as a raster reference image. For multi-page PDFs you can select which page to import. Adjust upload quality in the Import Settings panel before importing.

スクリーンショット

[__INSERT_IMAGE__]

Step-by-step

  1. 1クリック Upload PDF File.
  2. 2Select a PDF file.
  3. 3For multi-page PDFs, choose the target page in the dialog.
  4. 4The page is inserted as a reference image on the canvas.
💡

ヒント: Check the Import Settings panel to adjust upload quality before importing. Higher quality renders more crisply but produces larger files. 使用 Snapping Grid to calibrate the drawing scale to a known dimension on the PDF.

PDF にエクスポート

Create a single or multi-page PDF from selected drawing frame regions

PDF にエクスポート generates a vector-quality PDF with one or more pages. For each page you select a rectangular frame region on the canvas which becomes that page’s content area.

スクリーンショット

[__INSERT_IMAGE__]

Step-by-step

  1. 1クリック PDF にエクスポート.
  2. 2クリック Add Page in the dialog to add pages to the export.
  3. 3For each page, クリック フレーム button and drag a region on the canvas.
  4. 4Review page previews, then click 書き出す to download the PDF.
💡

ヒント: Export multiple sheet layouts in one PDF by adding one page per layout frame. Each page can cover a different area of the same drawing.

DXF / DWG

DXFファイルのインポート

Load DXF geometry and layers as editable CAD elements

DXFファイルのインポート parses a DXF file and converts supported entities – 行, polylines, メーカーのウェブサイトからDXFファイルを入手する, サークル, splines, and layers – into editable SkyCiv CAD geometry.

スクリーンショット

[__INSERT_IMAGE__]

Step-by-step

  1. 1クリック DXFファイルのインポート.
  2. 2Select a DXF file.
  3. 3File is parsed and supported entities are imported as editable geometry.
💡

ヒント: After importing, 使用する 範囲を拡大 to verify all geometry is present. 走る 重複を選択 to clean up any overlapping geometry from the import.

Import DWG File

Convert a DWG file to DXF and import it into CAD

Import DWG File uploads the DWG to the server, converts it to DXF using ODA File Converter, then imports the result exactly as SkyCivは、これらの複合形状を変換セクション法で処理します would.

スクリーンショット

[__INSERT_IMAGE__]

Step-by-step

  1. 1クリック Import DWG File.
  2. 2Select a DWG file.
  3. 3The DWG is converted to DXF on the server, then imported automatically.
💡

ヒント: DWG import requires a server-side conversion step – large files may take a moment. If geometry is missing after import, the DWG may contain unsupported entity types not included in the DXF conversion.

Export DXF File

Export drawing geometry to DXF for use in other CAD tools

Export DXF File converts the drawing geometry to DXF format and downloads it. ポイント, 行, polylines, メーカーのウェブサイトからDXFファイルを入手する, and layer assignments are exported. Dimensions and annotations are not included in the DXF output.

スクリーンショット

[__INSERT_IMAGE__]

Step-by-step

  1. 1クリック Export DXF File.
  2. 2Geometry and layers are converted to DXF format.
  3. 3The DXF file is automatically downloaded.
💡

ヒント: The exported DXF file is compatible with AutoCAD, FreeCAD, and other CAD software. Dimensions and leader annotations are not exported – 使用する PDF にエクスポート if you need annotated output.

Special Exports

SB

セクションビルダーへのエクスポート

Send hatch-based section geometry to SkyCiv Section Builder

セクションビルダーへのエクスポート transfers hatch-filled polygon boundaries directly into SkyCiv Section Builder for cross-section property analysis. The hatch pattern defines the section outline.

スクリーンショット

[__INSERT_IMAGE__]

Step-by-step

  1. 1Draw the section polygon and fill it with a Hatch.
  2. 2クリック SB export button.
  3. 3The hatch region is transferred as section geometry into Section Builder.
💡

ヒント: The section boundary must be defined as a closed polygon with a hatch fill. The hatch boundary – not the outline lines – is what gets exported to Section Builder.

S3D

Structural S3D Export

Export structural model data to SkyCiv Structural 3D format

Structural S3D Export analyzes the drawing for structural elements and generates a SkyCiv S3D-compatible JSON for use in SkyCiv Structural 3D analysis software.

スクリーンショット

[__INSERT_IMAGE__]

Step-by-step

  1. 1クリック S3D export button.
  2. 2Review the summary of detected structural elements in the dialog.
  3. 3Confirm to generate and export the S3D-compatible JSON.
💡

ヒント: Enable the 構造 toggle in the toolbar before drawing to ensure structural properties are tagged to your geometry, which improves the quality of the S3D export.
