Sheet Library

The Sheet Library is where you upload and organize floor plan drawings. These drawings serve as the background for creating spaces and modeling your building.

Uploading Sheets

Section titled “Uploading Sheets”

Supported Formats

Section titled “Supported Formats”
  • PDF - Preferred for vector graphics and multi-page documents
  • DXF - CAD drawings, converted to vector PDF on upload

Upload Process

Section titled “Upload Process”
  1. Navigate to Basis of Design > Sheet Library
  2. Click Upload Files or drag files into the upload area
  3. Wait for processing to complete
  4. Set the scale for each uploaded sheet

Multi-Page PDFs

Section titled “Multi-Page PDFs”

When you upload a multi-page PDF, each page becomes a separate sheet. You can:

  • Rename individual sheets
  • Delete unused pages
  • Reorder sheets

Scale Calibration

Section titled “Scale Calibration”

Accurate scale is essential for correct area calculations and load estimates.

Setting Scale

Section titled “Setting Scale”

Set the scale from the Scale column of the sheet’s row in the library table. Pick a standard architectural scale (for example, 1/8“ = 1’) from the dropdown, or check Custom to enter a custom ratio.

To derive the scale by measuring a known distance instead, open the sheet and use the Calibrate Scale tool in the viewer toolbar:

  1. Click Calibrate Scale
  2. Click two points of a known distance on the drawing
  3. Enter the real-world length
  4. Click Apply Scale

Tips for Accurate Scaling

Section titled “Tips for Accurate Scaling”
  • Use dimension lines on the drawing when available
  • Measure between grid lines or column centers
  • Verify scale by checking room dimensions
  • Re-calibrate if prints were resized

Scale Verification

Section titled “Scale Verification”

After setting scale, check that:

  • Room dimensions match the drawing
  • Total building area is reasonable
  • Space areas align with specifications

Sheet Organization

Section titled “Sheet Organization”

Naming Conventions

Section titled “Naming Conventions”

Use descriptive names that identify:

  • Floor level (First Floor, Level 2, Roof)
  • Building section (Wing A, North Tower)
  • Drawing number (A1.1, A1.2)

Sheet Order

Section titled “Sheet Order”

Arrange sheets in logical order:

  • Ground floor first
  • Upper floors in sequence
  • Roof plan last

Working with Sheets

Section titled “Working with Sheets”

Sheet Selection

Section titled “Sheet Selection”

Use the sheet dropdown in any view to switch between sheets.

  • File name and upload date
  • Scale factor
  • Number of spaces drawn on the sheet

Replacing Sheets

Section titled “Replacing Sheets”

HVAKR keeps sheet versions, so you update a drawing by uploading a newer revision:

  1. Click Upload Files and upload the new drawing as a new version
  2. In the library table, the Version column marks each page as Current Version or Old Version
  3. Click Use This Version on a page to make that revision the one the model reads
  4. Verify that spaces still align with the drawing

Deleting Sheets

Section titled “Deleting Sheets”

To remove a sheet:

  1. Select the sheet’s row in the library table
  2. Delete it from the selection toolbar

Deleting every page of an uploaded file removes the file from the library.

Best Practices

Section titled “Best Practices”
  1. Use vector drawings - Vector PDFs stay crisp at any zoom level
  2. Upload all relevant sheets - Include all floors and roof plans
  3. Set scale accurately - Verify against known dimensions
  4. Name sheets clearly - Use consistent naming conventions
  5. Organize before modeling - Set up sheets before drawing spaces
