Paper to CAD - convert inventory plans into CAD

General requirements for vectorization

The plans must be scanned.

Standard performance vectorization

The following restrictions are considered standard services and must be accepted by the client as proper performance:

• Geometric implementation: The plan is transferred one-to-one to CAD as far as possible, based on the geometric representation of the lines.

• Conversion restrictions: A full conversion is not guaranteed. There may be technical discrepancies between the conversion data and the original data.

• Implementation area: Only representations within the plan framework are implemented.

• Texts: Texts are recorded and displayed, but they are not part of the service. Deviations from the original text may occur and will not be corrected.

• Dimensional deviations: Despite great care, discrepancies may occur between the finished CAD drawing and the original. This may be due to errors in the original document, distortions during scanning, or dimensional differences due to manual adjustments.

• Missing dimensions: If there are no or incomplete dimensions in the plan, the drawings are implemented using the original dimensions. No measures are calculated by addition or other mathematical operations.

• Individual plan implementation: Only a single plan can be implemented with dimensional accuracy at a time. Dimensional connections to other plans cannot be established, especially in the case of superimposed floor plans.

• Color conversion: The colors in the original plans can only be roughly implemented in CAD.

Vectorizing land use plans

Requirements for vectorizing land use plans

• The digital corridor map must be available as a DWG or DXF file.

Standard performance Vectorize land use plan

The following restrictions are considered standard services and must be accepted by the client as proper performance:

• Unimplemented elements: Contour lines and tree symbols are not vectorized.

• Scope: Only representations within the scope are implemented.

• Differential data: Only the difference data for the digital corridor map is drawn. Lines and objects that are already included in the digital corridor map are not vectorized but transferred directly to the drawing.

• Buildings: Buildings are only taken over from the digital corridor map.

3D models - creating 3D drawings

We create 3D building models for specialist planners, architects and building owners. These models include exact dimensions, areas, volumes, and other specific properties. All necessary plans, such as views, sections, floor plans and perspectives, can be derived from the 3D CAD models.

3D building models created by us:

• Serve as a basis for further processing in BIM.

• Can be executed in various LODs (Levels of Detail).

• Form the basis for photorealistic representations through renderings.

LOD - Level of Detail - detailed presentation in 3D models

Our 3D models are classified according to four different display types (LOD):

• LOD 100: For simple mass models.

• LOD 200/300: Standard for exporting in IFC format and for data exchange.

• LOD 400: Only possible based on inventory plans that contain this information and are transferred to the 3D model.

Benefits of our 3D models:

• Reliable basis for further processing.

• IFC format for flexible reuse.

• Compatible with leading energy computing software solutions.

• Adapted level of detail (LOD) specifically for energy calculations.

• Tested and verified for use with Hottgenroth (HottCAD) and E-CAD (Cascados) for seamless integration.

Specifications for importing into E-CAD

Good quality IFC models can be provided for work in E-CAD. All parts of the “shell” (walls, windows, doors, roof, ceilings) can be imported correctly. The 3D model is modeled in a simplified 3D representation, which does not contain any fixed installations and systems, but only the building envelope. The representation of the interior walls is optional and is not included in the basic model.

Attention: Due to problems with the IFC interface, stairs, wall openings, skylight windows and curtain walls are not correctly recognized. We provide an Excel spreadsheet with full information about these items so that they can be considered correctly.

As Built Services

Preparation of CAD drawings for surveying work

prerequisites

The services described below for the production of CAD drawings can only be implemented if:

• Free! has recorded the local requirements, or

• The customer has provided the necessary information in an appropriate form.

The appropriate form must present the facts to be drawn in a clear and comprehensible manner. Only clear facts are implemented. Analogies or conclusions arising from building geometry or other planning conditions will only be made upon written request from the customer or through an on-site inspection by Free! considered. The representations are generally on a scale of 1:100 and are presented in abstract form. All dimensions are calculated orthogonally from the building and presented orthogonally.

Georeferencing Requirements

The plans are available scanned. Reference objects are required for georeferencing. There are either coordinates entered on the plans or cadastral maps are available, either in scanned form with coordinates or in the form of digital GIS data in AutoCAD DWG format.

Georeferencing standard performance

The affine transformation is offered with 4 vertices of plans already available in grid form based on existing coordinates.

Georeferencing additional services

Free! provides, in particular, the following additional services by appointment within the framework of existing technical and operational options for a separate fee, which is based on the applicable price list:

scanning

Scanning Requirements

The plans are available rolled or folded on transparent films or in paper form. The plans show little or no damage; cracks or holes in particular are professionally glued. There are no metal clips or parts that prevent paper entry on or on the plans. If the planning documents exceed the width of approx. 1.05 meters, the plans can only be scanned when the planning documents are cut. Cutting is charged according to effort. Offers are only binding for DIN sizes. Oversized plans or plans that cannot be processed with a feed scanner for the above or other reasons are billed on an hourly basis. Unless otherwise agreed, the price lists apply to scanning in their current version.

Standard scanning performance

Depending on the template, the planning documents are scanned in color or in grayscale or black and white. By default, the resolution is 300 dpi.

Free! provides, in particular, the following additional services by appointment within the framework of existing technical and operational options for a separate fee, which is based on the applicable price list:

• Remove metal clips or similar objects

• Plus size scanning
