Designing DXF Files for Optimal Processing
To ensure a smooth and efficient workflow, it's crucial that customers provide correctly formatted DXF files. This guide outlines the required design specifications for each component type to minimize errors and reduce custom work by our in-house team.
General Requirements
No 3D Components:
Ensure all elements are in 2D. Before saving, use the FLATTEN command to eliminate any unintended 3D elements. If you do not have the full version of CAD, this cab be done in QGIS using the Set Z value command and setting it to 0.
3D solid block elements are not supported.
Single Entities per Component: Each component must be represented as a single entity (polygon, closed polyline, line or point).
No Overlapping Elements: Polylines, lines and polygons should not cross or overlap incorrectly in the same layer.
Layer Organization:
Each component should be assigned to a separate layer.
Multiple layers can be selected for a component, but you can't place multiple components in a single layer.
The CAD drawing should be georeferenced as the EPSG needs to be provided on upload to the platform.
Blocks are not supported and the EXPLODE command should be used on a drawing before uploading.
Xrefs are not supported. Any Xrefs should be inserted in to the main CAD file and all Xref links deleted.
There can be no hatches in the CAD file. The platform cannot display hatches.
The drawing should be purged before saving to remove un-required layers.
The CAD file needs to be provided as a DXF 2010 version.
The DXF should be <500MB, if you have a large number of components in your drawing, you may need to split the drawing into several files for upload.
The file should have less than 200 layers.
At the moment text is not supported. Therefore any text within the DXF will not be displayed on the platform.
Component-Specific Design Rules
Panels
Must be drawn as separate polygons or closed polylines.
A number of panels cannot be represented by a roster of crossing lines.
If you use closed polylines, they will be converted by Sitemark into polygons automatically.
Piles
Must be represented as points.
Trenches
Must be drawn as lines or polylines.
The line should be indicating the centre line not the outlines of the trench
Fences
Must be drawn as lines or polylines.
Foundation Beams
Must be drawn as separate polygons.
Tables
Must be drawn as separate polygons or closed polylines.
If tables are represented as closed linestrings, ensure the last point connects to the first point to form a closed shape. These will be converted into polygons automatically.
Other Components
Can be represented as polygons, polylines, lines, or points, but each must be a single entity per component.
By following these guidelines, you can provide DXF files that integrate seamlessly with our system. If you have any questions, feel free to reach out to our support team.
