CATIA Tutorial for surface control
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.
Create, experience and share your visions in 3D
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.

Create Scenes in CATIA
This CATIA tutorial shows you how to Create Scenes and use them for Draughting
Ever created an isometric view in the Draughting work bench of an assembly, then changed the location of parts in an assembly and when you go back to your drawing you find it has updated the drawing to that of the assembly. This is good to have as it is part of the power of CATIA with its associativity. But sometimes you want views to keep their positions, i.e. you want an assembled isometric view as well as an exploded view.
We have our assembly…
We create an isometric view…
Now the problem arises when you edit the main assembly and then the drawing up dates as well. So we need to create a scene, for exploded views or even where only specific parts are shown.
Make sure you select the full overload option before clicking OK.
Hide, show, move and rotate parts until you get the view you want and then click to exit the scene (same icon as exit sketcher), you can see in the tree that there is a new Scene.1 that has been created.
Here are only a few parts that need to be shown…
An exploded view…
Now to apply these scenes to the drawing, double click on the scene you want, then from the Draughting workbench create a view and in your assembly which should be in the scene you want click on the Scene you want in the tree first, then click on the model to generate the view.
