Extract text from DDP files
To convert your DDP file to another format, you need DreamPlan Home Design or other 3D software.
To convert other file formats to the "Home Design Project" file type, you need software like DreamPlan Home Design or a similar tool.
A .DDP file is most frequently a proprietary project file created by NCH DreamPlan, a home design and landscaping application. These files store the complete architecture of a project, including 2D floor plans, 3D models, texture mappings, and furniture layouts. Users typically encounter friction here because a .DDP is not an image file; you cannot simply email it to a contractor or client and expect them to view the design on their phone or browser. It acts as a "save state" that requires the original software to render the visual elements. To share these designs effectively, users must convert the project into standard formats like PDF for documentation or JPG/PNG for visual presentation.
Alternatively, in the construction industry, a .DDP file may be a budget archive generated by PRESCOM software. These files contain cost estimations, material lists, and financial data compressed for storage. The main challenge with this variant is data accessibility; legacy budget files are often locked within the PRESCOM environment, making it difficult to analyze figures in modern spreadsheet tools. Converting these files to CSV or XLSX is essential for importing data into Microsoft Excel or other financial software. A third, less common use case involves Embarcadero Delphi, where the extension represents a Diagram Portfolio used by developers to visualize code structure, though these are rarely converted for non-development use.
Convert.Guru analyzes your DDP file, detects the exact format, and lets you read the text inside.
Users also converted DDPID, DPP, DAT, PDF, MKV, ZIP, JPG, WAV, VPJ, RSM, DCR, DPR and ISO files.
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 "Home Design & Budgeting" 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 "Home Design & Budgeting" category.
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.
