production drawing.
Paper space turns the live model into dimensioned, scaled sheets with a title block — ready for print or PDF. Sheets are views of the model, not exported copies: change the part and the drawing follows. Standard CAD formats move geometry in and out.

Sheets are views of the model, not exported copies.
Change the part and the drawing follows: views rebuild when the model changes, and every sheet prints or exports with its own page setup.
Paper space & sheets
- ISO A0–A4, ANSI A–E and custom sheet sizes; first- or third-angle projection
- Scaled projected views: orthographic, isometric, dimetric, trimetric, plus detail windows
- Hidden lines, per-view layer visibility, lock and rename
- Native border and title block; text and dimensions on sheets and views
- Views are associative: they rebuild in the background when the model changes
- PDF per sheet or as one multi-sheet document
Printing
- Print and preview for model space and sheets
- Plot-style tables (monochrome, standard), exact or nearest colour matching
- Fit to page or exact scale, margins, copies, selection only
File exchange
Standard CAD formats move geometry in and out.
| Format | Import | Export |
|---|---|---|
| .eye — native — with features, constraints, variables, sheets | yes | yes |
| DWG / DXF — selectable AutoCAD version, layouts ↔ sheets | yes | yes |
| STEP · IGES | yes | yes |
| STL · OBJ | yes | yes |
| IFC · JT · DWF | yes | no |
| PDF — model, single sheet or all sheets | no | yes |
Import can merge into the open drawing; operations run asynchronously, raise events and can be restricted by the host to the formats you want to offer.

01Paper space & printingSheets with borders and title blocks, scaled views of the model, texts and dimensions on the sheet, page setup, plot style tables, printing, and PDF output of one or many sheets.12 capabilities
- Sheets use the ISO A0 to A4 or ANSI A to E formats, with a border and a title block whose title, sheet number and scale fill in automatically, or a custom paper size, and can be copied with or without their views, renamed, reordered and deleted.
- Hidden-line views show the whole model or a chosen area in an orthographic, isometric, dimetric or trimetric direction, at an ISO 5455 or imperial scale, a custom scale or one that fits the sheet, and a view too large for the sheet is refused with a suggested scale.
- Each view can be locked against moving and rescaling, hide chosen model layers or single entities in that view only, and choose whether hidden edges are drawn, entity colours kept and regions filled.
- The paper space tracks which views a model change has left out of date and rebuilds only those, and with a layout control attached the rebuild can run in the background, filling the views in one by one with progress events and a way to cancel it.
- Texts and linear dimensions can be placed on the paper of a sheet, and dimensions inside a view between two model points that measure the model and follow the view through rebuilds and rescaling, all undoable and saved with the drawing.
- Printing or previewing the active sheet, all sheets or a range of positions and names runs one print job per run of sheets sharing a page setup, so every sheet prints on its own paper, orientation and margins and with its own pen table.
- The model space prints or previews fitted to the page or at a set scale, of its extents or the current view and optionally of the selection only, and plot style tables, built in or loaded from a file, set the printed colours and line weights of prints and sheet PDFs.
- Each sheet keeps its own page setup (standard or custom paper, orientation, margin, plot scale, pen table and printer), and sheets export to PDF with it, one sheet to a page or a set of sheets to one file with a page per sheet, as 3D PDF.
- Before every print or print preview of the model space or of sheets, the host receives all its parameters (space, settings, pen table, printer, sheets and their page setups) and can cancel it.
- Before every print or print preview of the model space or of sheets, the host receives all its parameters (space, settings, pen table, printer, sheets and their page setups) and, for the model space, the millimetres on paper of one drawing unit, so it can size symbols, texts and title blocks on paper or cancel the print, and afterwards it learns whether the print completed, failed or was cancelled.In the next release
- Sheets, views and their settings can be driven from code through the same operations the commands use, where every change is one undo step and raises an event, and an operation that cannot be carried out is refused with a typed reason before anything changes.
- Sheets are shown in a WinForms control that a host can extend with its own tools, with a pick on the paper, the model point under a point of a view, a picture of the sheet at any size, and refusal messages worded like the built-in commands in the user's language.
02Files & interoperabilityThe native EYE format; import of DWG, DXF, DWF, STEP, IGES, STL, OBJ, JT and IFC; export to DWG, DXF, STEP, IGES, STL, OBJ and PDF; merging a drawing into the current one.7 capabilities
- The native EYE format saves the whole document, including layers, blocks, the host's own data, constraints, variables and sheets, and saving can run in the background.
- DWG, DXF, DWF, STEP, IGES, STL, OBJ, JT and IFC files open as the current drawing, in the foreground or in the background, and a file that cannot be read leaves the current drawing as it was.
- A file in any supported format can be merged into the current drawing as one undo step without changing the view; layers, blocks and styles whose name is already in use keep the current definition, and incoming sheets with a name already in use are renamed.
- The drawing exports to DWG and DXF in a chosen AutoCAD version, and to STEP, IGES, STL, OBJ and 3D PDF, in the foreground or in the background.
- Sheets are read from the layouts of DWG, DXF and DWF files and written to DWG and DXF layouts, with each view either exploded into plain geometry or kept as a live AutoCAD viewport.
- The host can restrict the formats offered in its file dialogs and accepted by each import or export, for licensing or to keep the interface simple.
- Events before and after every import and export let the host veto it or adjust its options, one event reports every new, opened or merged document, and the host is warned when an export or a merge cannot carry the constraints or parametric features.
