CATIA reseller South Africa | CATIA CAD CAM | CAD CAM Software | CDC | PLM Solutions

CDC is comprised of qualified mechanical engineers who can assist you with stress analysis services in order to help analyse and improve the quality and performance of your products in the early stages of your design process when the cost of change is low.

By choosing CDC as your stress analysis partner you are taking advantage of our years of mechanical engineering design experience and knowledge. All of our mechanical engineers use the world’s leading CAD/CAM/CAE software, CATIA V5, which means that your project will be completed faster with the benefit of virtually simulating performance to ensure that it is right the first time with no need for costly prototypes.

Ever had a sweep that just seemed to give errors and did not want to form the way it should. One thing we at CDC have learnt is that CATIA has almost no limits as to what can be done with Surfacing. There is always a way! This CATIA tutorial will show you how to control a sweep more effectively.

Here we have an extruded surface created from a door punch surface. Now we would like to pinch a new surface inward at 45deg to the extruded surface and at a length of 70mm.

Here everything looks fine but if we increase the sweep length to 250mm, we can see that the surfaces are 45deg but the direction is wrong and there are warnings that appear (still nice that CATIA can generate a surface though (“,) ). This is because the 45deg is normal to the surface, so in sharp corners errors will normally occur.

So, how do fix this sweep? Easy… we give it a back bone or a “spine” to give it some sort of direction. We create a sketch an in it a circle. The dimensions of the circle are not critical.

Now back in the Sweep definition, we need to add the sketch as a spine. And then on preview we can see how smooth the sweep is now.

Set the sweep length back to 70mm and know that it is much easier to manufacture now as the surface is smooth and has no sharp edges or undercuts.

I hope you enjoyed this CATIA Tutorial brought to you compliments of CDC your technology partner.

We can create interactive product documentation, animation, technical illustrations and more by reusing your 3D CAD data. 
We use 3DVIA Composer to avoid a costly deliverable production process, having to re-do documentation when there is a design change and more…

By using 3DVIA Composer, we can quickly and easily automate your deliverable production processes while reducing costs and improving quality.

Now you don’t need to manufacture your product before you can market it. Using a free player anyone can view your lightweight 3D data, with animations designed to show your customer what you want them to see.
