Practice

Welcome to my Practice page. Majority of these mini-projects are created on CATIA V5 but other CAD packages such as Inventor, Siemens NX, AutoCAD, Revit and Solidworks may be featured.

3D Geometry Models

3-Dimensional Geometry Models in Catia V5.

(Posted on Intro Page)

Rectangular Prism - Rectangle Extrusion

Cylinder - Circle Extrusion

Sphere - Revolved Semi-sphere

Cone - Revolved Right Triangle

Torus - Revolved Circle along axis X distance away

Rectangular Pyramid - Surface Modeled Triangles

Approx Practice: 45 minutes

Car Surface Model

Car Surface Model Using Catia V5

Practiced Cuts and Extrusions of model. Smoothed out car cabin and hollowed out top for Windows. Another enjoyable way to model complex and smooth shapes.

Approx Practice: 30 min

Gasket Seal Model and Drawing

Gasket Model Using Catia V5

Sketched Concentric Circles, inside sketch circle, outside construction circle to Constrain outer holes.

Used an angled constrained to lock holes in place and sketched to connect the outer circles to main circle.

Used Hole Feature In centers of each curve.

Extruded whole sketch.

Approx Practice: 1.5 hours

Bracket Design Assembly

Bracket Piece

Designed using extrusions and offset planes.

Extruded Cylinder Piece and Rectangular Piece separately and connected each using an extrusion and a fillet to smooth it down.

Implemented three counter-bored holes for bracket shaft and screw holes.

Bracket Shaft

Extruded Cylinder for middle chunk and mirror extrusion for shaft ends.

Bracket Base

2 Part - Rectangular Extrusion

Holes to Fit Screw ends.

Bracket Screw Head (2x)

A universal screw piece imported from McMaster-Carr.

Thread Size: 1/4"-20

1" length

Zinc Alloy Plated Steel material

Bracket Assembly

Assembly of Bracket using all parts. Constrained using surface and insert constraints.

Approx Practice: 1.5 hours

Revit Family Model and Inventor iLogic

Modeled a 3x3x2 box on top of a 4x4x5 box in both Revit Family Models and Inventor as a single part.

Learned key basics in Revit using Reference planes, align tools, and parameter changes.

The objective was to discover if Revit is sufficient enough to model furniture and utilities and add them to an existing building. And if not, which program does it better?

Turns out, one can create models in Inventor then export them to Revit building layouts. Creating models are much easier and twice as fast in Inventor compared to Revit family modeling.
