017 Cube Modeling using Parameters

In this tutorial, a Cube is modeled using parameters where all the edges of the cube are linked with only one parameter "L". Upon changing this parameter all the cube edges are changed accordingly. The only module used in this tutorial is "Part Design".

This tutorial is quite simple. The Parameter is defined and given the required length which is - in our case - 10mm. Then the sketch of the square is made up where the length of the two sides is linked through a formula to the "L" parameter. Using the Pad tool, the extrusion length is defined the same way. At the end of the tutorial, some manipulations were done on the cube to try different lengths of the edge.

Here is the video that shows the modeling of the Cube:

016 Adding 3D text "impression"

In this tutorial, 3d text is created using the drawing module and saved as DXF file. This text is then added to another part - in the part design module - as if impressed on it using the pad tool.

Creating and adding 3d text in catia is so simple and is done through following these steps:

• First, the text is written in the drawing module. After writing the text, you may right click on it, click on properties and change the text type, size, color, weight... etc. according to your desire. then the file is saved as dxf file.

• Second, open the dxf file and copy the text through selecting the text and right clicking on it. Open the part which you want to add the text to. choose the sketch tool and choose the surface where you want to add the text. and then paste the text and use the transformation tools to adjust the size and orientation of the text.

• Third, using the pad tool the text will be extruded out of the part. the pocket tool could also be used to engrave the text inside the part instead.

Here is a video that shows how to add 3d text in Catia:

015 Spoon Modeling

In this tutorial, a simple spoon is modeled using generative surface design, free style and part design modules in Catia. The spoon is shown in the following image:

The spoon modeling is done through following these steps:

• In the generative surface design, the main profile is sketched using the spline tool.

• Surface is extruded using the surface extrusion tool.

• Horizontal cutting surface is modeled perpendicular to the first profile and the cutting surface is modeled using the net surface tool in the free style module.

• The net surface is supported by three spline profiles, the middle of which is modeled a bit deeper in order to obtain a bowl-curvature in the spoon.

• The spoon surface is extruded using the pad tool in the part design module and the spoon edges are filleted using the fillet feature in the part design module.

Further modifications are done according to your design shaping desire.. enjoy !!
