papacad.com offers professional CAD projects prepared in leading CAD programs such as Inventor 2014 and Solid Works 2017. We design CAD projects in a team of experienced design engineers. Who attach significant importance to the quality and correctness of 3D models and 2D CAD flat drawings. 2D CAD DWG executive documentation is created on the basis of professional advanced models and 3D assemblies. All drawings are created solely on their basis. Each CAD design is unique and reflects contemporary design trends in mechanics. We use standard elements according to ISO and EN standards as: electric engines, pneumatic and hydraulic actuators and fasteners.
Our CAD projects are available as a purchase and free download. Our aim is to create with the same attention to detail and quality level for paid and free products.
Complete CAD designs, 2D drawing documentations or CAD 3D models that you can download are always packed with ZIP (available as a component of most operating systems.) If you find this lack, you can download it for free: Winzip , 7Zip, WinRAR.
Inside every ZIP package with a CAD design there are complete set of files of a given project.
This means that the ZIP package with the documentation that you downloaded contains complete set of components chosen type of documentation.
A single CAD design is placed in a catalog with a name describing: project theme, documentation type (Inventor 3D & 2D 2014, AutoCAD Mechanical 2004, 3D STEP, etc.).
Within the directories there is a structure for identifying directories and CAD files.
The structure of CAD design is as follows:
When you open the Inventor .ipj project file, you will see an identical structure as in the operating system browser:
The main assembly and subassembly also have a specific hierarchy, which is result from the construction of the device and the importance of the subassemblies in the structure:
When any 0f the 3D CAD projects is opening by Inventor , you will see a tree manager on the left, with the structure of the project and the names of the files. These names closely match the file names in the project directories stored on the disk. Each CAD file in our CAD projects has a strictly established name and location that uniquely identifies it in the project structure:
3D layouts have a structured naming and physical structure. This makes it easy for anyone to understand the design, attachments, dependencies and location.
Inventor DWG and AutoCAD DWG 2D CAD drawings has the same naming conventions as 3D models related to CAD files naming. Keeping proper CAD files and CAD drawings names allows to maintain clarity. Increases the speed of finding the right files, CAD drawings, and keeps working on the project “in check”:
3D parts and 2D CAD drawings names in BOM tables also have an identical hierarchy. CAD drawings nubering is compliant with ISO standards and factory standards worldwide. Every engineer familiar with the naming and numbering method of technical drawings reads our 2D working documentation without any problems:
The 2D CAD drawing table contains information about:
BOM list contains:
In the 2D CAD assembly drawings, 3D drawings and working DWG drawings, we provide all the information necessary for the assembly and produce process:
3D CAD design, 3D models and assemblies standards:
Technical 2D drawings standards:
