3D CAD MODELLING

Our Expert CAD Drafting team will assist you with your 3D CAD MODELLING Requirements

WHAT IS 3D CAD MODELLING

3d cad modelling australiaThere are several different types of CAD, each requiring the operator to think differently about how to use them and design their virtual components in a different manner for each.

There are many producers of the lower-end 2D systems, including a number of free and open-source programs. These provide an approach to the drawing process without all the fuss over scale and placement on the drawing sheet that accompanied hand drafting since these can be adjusted as required during the creation of the final draft.

The 3D wireframe is basically an extension of 2D drafting (not often used today). Each line has to be manually inserted into the drawing. The final product has no mass properties associated with it and cannot have features directly added to it, such as holes. The operator approaches these in a similar fashion to the 2D systems, although many 3D systems allow using the wireframe model to make the final engineering drawing views.

3D “dumb” solids are created in a way analogous to manipulations of real-world objects (not often used today). Basic three-dimensional geometric forms (prisms, cylinders, spheres, and so on) have solid volumes added or subtracted from them as if assembling or cutting real-world objects. Two-dimensional projected views can easily be generated from the models. Basic 3D solids don’t usually include tools to easily allow motion of components, set limits to their motion, or identify interference between components.

There are two types of 3D solid modelling

  1. Parametric modelling allows the operator to use what is referred to as “design intent”. The objects and features created are modifiable. Any future modifications can be made by changing how the original part was created. If a feature was intended to be located from the centre of the part, the operator should locate it from the centre of the model. The feature could be located using any geometric object already available in the part, but this random placement would defeat the design intent. If the operator designs the part as it functions the parametric modeller is able to make changes to the part while maintaining geometric and functional relationships.
  2. Direct or Explicit modelling provides the ability to edit geometry without a history tree. With direct modelling, once a sketch is used to create geometry the sketch is incorporated into the new geometry and the designer just modifies the geometry without needing the original sketch. As with parametric modelling, direct modelling has the ability to include relationships between selected geometry (e.g., tangency, concentricity).

What is a 3D CAD Modelling Service?

A 3D CAD Modelling Service uses 3D CAD Software such as Solidworks, Inventor, Catia or Pro-E for creating components in 3D. 3D CAD packages (as the name suggest) create 3D CAD models first from which one then an produce:

  • Fully Dimensioned Drawings to Australian Standard
  • Renders/Visualisations
  • 3D Print files (STL)
  • Interference Checks (Collisions, Alignment etc.)
  • Animations

What 3D CAD Modelling Services does Draftings Australia offer?

Most of our Designs start in 3D CAD, even though the drawings such as Manufacturing Drawings are 2D (so you can print them on paper). We only use 2D CAD (Autodesk AutoCad) for simple Mechanical & Electrical Drawings (MEP) as well as Schematics. Everything else gets created in 3D first, which is a far more efficient way to produce drawings these days.

Also relevant is that changes to parts do not get carried out within the drawings but within the 3D CAD model. The Drawings update automatically (one might have to add/delete a dimension or two). However, one does not have to update all the drawings views and check that they all align.

The majority of our projects are carried out with Solidworks. We own several Solidworks licenses which are supplied by our VAR.

Drawings Types that start of as 3D Models are:

  • Datasheets
  • Manufacturing Drawings
  • Fabrication Drawings
  • Patent Drawings
  • Shop Drawings

3D Drafting Design Tools and Software

Our Expert Engineers & Drafters are versatile enough to use any software that your process might require. We have successfully managed Drafting and Design projects involving software such as AutoCAD, ArchiCAD,Solidworks, Revit Architecture, Architectural Desktop, Microstation, and 3D Studio Max.
