Convert DDP to another file type
To convert DDP project files to another format, you need DreamPlan Home Design or other 3D software.
Convert a file to DDP
To convert other file formats to the "Home Design Project File" file type, you need software like DreamPlan Home Design or a similar tool.
About DDP files
A .DDP file is typically a proprietary DreamPlan Home Design Project file created by NCH Software, or a PRESCOM Construction Budget file. DreamPlan uses these files to store 3D building models, textures, and 2D floor plans. PRESCOM uses them to manage complex building estimates. Additionally, Embarcadero Delphi utilizes the extension for diagram portfolios.
The main disadvantage of .DDP files is their severely restricted compatibility. You cannot open a DreamPlan file in a web browser or import it directly into professional CAD tools like AutoCAD or SketchUp. Similarly, PRESCOM files are unusable without the original estimating software, locking your financial data behind a proprietary wall.
To share these files with clients or colleagues, DreamPlan users typically need to export their 2D layouts and 3D renders to standard PDF documents or JPG images. Interestingly, PRESCOM files are actually standard ZIP archives in disguise. Renaming the file extension to ZIP allows you to extract the raw data inside.
Because these are closed formats, they are incredibly difficult to process without the native application. Standard online converters lack the algorithms to parse proprietary 3D geometry or specialized budget data.
Convert.Guru analyzes your DDP file, detects the exact format, and lets you read the text inside.
If you want to convert DDP file to ISO, OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D, STL or PLY, you can use DreamPlan Home Design or similar software from the "3D Home Design Storage" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to DDP, try DreamPlan Home Design or another comparable tool in the "3D Home Design Storage" category.
The DDP Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DDP converter.
