The process to import plugin data to the drawing.tool is continuously improving. As we add more functionality and updates, this article will change to meet the current existing workflow. For now, here are some tips you can apply to your model to have a smooth import and reduce model clean-up inside drawing.tool.

Wall-based Import

A wall-based import occurs when individual elements are detected by the plugin and rebuilt in the drawing.tool platform. Here are some tips that can help you avoid messing drawing.tool imports per category.

  1. Overall

    1. Only walls, floors, windows, roofs, spandrels and skylights are imported into drawing.tool. Everything outside of these categories will not be imported.

  2. Walls

    1. At every level, all wall objects should have identical Top and Base offsets.

    2. Shaft walls and Column wrapped walls do not import.

    3. Walls that are closely placed together or are overlapping will be skipped by the import or will cause conflict in the drawing.tool.

    4. Floating walls do not import. Low-height walls do not import. However, both can be modeled in the drawing.tool interface.

    5. Curved walls will not import curved but will be segmented or faceted based on the complexity of the curve.

    6. Mitering Wall Joints can help reduce gaps across the model's envelope and better render floor slabs.

  3. Windows

    1. Having windows hosted on walls can reduce overlapping windows. Sometimes walls have cut-outs and windows are placed in-place of the cutout, without either object interacting with one another. This will cause the import to draw two windows, one for the cutout and one for the window.

  4. Floors

    1. Multiple floor slab elevations at the same level do not import well.

  5. Roofs

    1. Sloped roofs are not imported. Instead, they can be drawn after being exported to drawing.tool. Take a look at this article for information.

  6. Skylights:

    1. Currently only rectilinear skylights placed on flat roofs will be imported with accurate positioning and rotation angles.

  7. Height

    1. Double-height spaces will not import. Instead, they should be adjusted once inside the drawing.tool.

Room based import

Instead of rebuilding the model by individual objects the room-based import collects data from Revit Rooms. To generate a room-based import, use the Export Rooms button in the Revit add-in, immediately after using the Export All function.

Happy modeling!
