CATIA tips and tricks

Make your work faster and easier with these CATIA tips and tricks.

Introduction

First of all if you are an engineer who spends a lot of time modeling , this post is perfect for you. Did you ever think how can you speed up your modeling and what can you do better. There are a lot of stuff to do if you are on the beginning of the process. You need to figure out how to organize your models. Help yourself with these CATIA tips and tricks. I think you need to start with one good database of standard part. Certainly you need some time if you want to use all of these tips. 

1. Make base of standard parts

You need to make parametric parts. In one part you will have all the variants. So whenever you need this part you can just use it. If you are working in team this is even better because everyone will have same part. Furthermore you don’t need a lot of knowledge to do this.  For example you can go on FIBRO and see their catalog of standard parts.

This is one picture from FIBRO catalog. So with this dimensions you can make parametric model. Even more if you want to read more about parametric model you can do it on this link . We made this part for you. You can see all the pictures and you can also download this file and table from excel. Download.

Also make a copy of every part that you use often. And make database of your projects. So every time you get something similarly, you can use your database. It is like database, database…

2. Make Powecopies

A powercopy can be any set of CATIA features. It can be very simple, like  one body and pad, but it can be very advanced too. You can make very advanced powercopies with a lot of elements, even rules and tables. One time you make it and use it as many time as you want. So it is very powerful stuff to use. Also it is perfect for teamwork. One person can make powercopies for everyone. You can use parametrization for powercopies too. You can get very similar model with this. See more on the video below.

You can also connect powercopies and macros, see more here.

3. Use boolean operations

Boolean Operation is one important part of CATIA. Actually it is not in CATIA only it is in cad. So you can find it in all types of cad software. When you come to boolean Operation it is used to add(combine), subtract(remove) or intersect the object. So if you want to add or merge two object you have to use add option, but object should be teach each other. If you want to remove material of a object from other teaching or intersecting object, then you should use subtract option.And the last one is Intersect. It is used when you want to remove or save the intersecting part. Hence you can easily organize you tree and your model. Certainly you don’t want to have like 100 pads or pockets in row.  

4. Make basic tree for every part

You want to have organized part with same structure. Use boolean to make that tree and make one start part. So when you want to create new part, use that one with the structure.

Finally this is simple example of tree. You have main body, milling and drilling. In many body you can add your main features and milling and drilling are clear. 

5. Icons and schourcuts

Organize your icons and shortcuts. You really need to make shortcut for every tool that you use often. Because it can save a lot of time for you. So once you start doing it, you can’t stop. In the end you want to have shortcut  for every tool.

6. Publications

Many parts contain important features that the designer knows will be used in other parts, or to constrain the part in an assembly such as hole centrelines, mating faces etc… There are three problems with this however:

1) Important features are often hidden amongst large numbers of construction features that are of no interest to other users.

2) There is often multiple ways of defining the same feature when creating constraints and importing part geometry.

3) Similar features in similar parts may be modeled in a completely different manner. Meaning that replacing one part with a similar part will often cause it’s links to fail.

Therefore to avoid this problem a publication can be used to declare the centreline and this publication can be used whenever a constraint is made to the centreline or not. This means that if the published feature is removed or replaced, CATIA will immediately inform the user that the publication no longer points to an existing feature. The user can then re-point the publication to a replacement feature and all of the assembly links will automatically be corrected.

7.Macros

Finally use macros to speed up you processes. This site is completely about that. You can read more in tutorial section. 

We hope that these CATIA tips and tricks will help you a lot.
