3D Online CAD Design 

Standards in our 2D & 3D CAD Library

We design with CAD software – it’s Autodesk Inventor 2014 right now.

Our CAD projects are available as a purchase and free download. Every project has identical quality, without distinguishing whether it is a free product or not. 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 project 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 project 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 files.

The structure 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 open by Inventor any 3D CAD assembly, you will see a tree 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:

 

CAD files structure in project

 

3D layouts have a structured naming and physical structure. This makes it easy for anyone to understand the design, attachments, dependencies and location.

 

DWG download CAD files

 

Inventor DWG and AutoCAD DWG 2D documentation has the same naming conventions as 3D model files and assemblies. Keeping proper names allows you to maintain clarity, legibility. Increases the speed of finding the right files, CAD drawings, and keeps working on the project “in check”:

 

 2D drawings files

 

Parts and drawings names in BOM tables also have an identical hierarchy. 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:

 

2D drawings DWG

The drawing table contains information about:

  • the name of the project,
  • name of the parent assembly,
  • drawing number,
  • change number,
  • sheet size,
  • number of sheets of one drawing,
  • scale,
  • designer.
  • producer,
  • weight,
  • designing date,
  • projection method (European, US)

BOM list contains:

  • name of part,
  • drawing number or standard,
  • item number,
  • quantity,
  • change number,
  • material,
  • weight, and
  • comments.

 

BOM 2D drawing stadnards

In the assembly drawings and working drawings, we provide all the information necessary for the assembly or produce:

  • numbering,
  • fittings,
  • tolerances,
  • deviations,
  • production conditions,
  • production methods,
  • technological annotations, etc.

General design 3D standards

3D CAD models and assemblies standards:

  • Global Unit System – SI (metric)
  • Mechanical projects guideline – European Machinery Directive 2006/42 / EC
  • Selection of structural components – calculations of strength, performance and durability (Directive 2006/42 / EC)
  • Components  selected – European standards EN – ISO (European producers database or global)
  • Standarized parts – EN ISO standard – inside project folder
  • 3D parts, sufraces – NURBS

Technical drawings standards:

  • Projection of 2D drawings – european method  EN ISO 5456-2: 2002
  • Dimensioning, general rules – ISO 128
  • 2D documentation – Inventor DWG 2014
  • 2D export : AutoCAD 2004 DWG and PDF

NOTE: Files with appropriate calculations may not be in each  projects!
