Current practice in architectural and engineering design involves workflow methods that can have many stages and steps that challenge the efficacy and quality of the design and construction process. Unnecessary costs accrue through design collaboration delays and redesign or rework at any stage which challenges the business model of all participants.
Over the past couple of months, we published a series of articles related to Modelling Methodology in CATIA V5.
The presented articles discuss the entire process for parts that are mainly prismatic in shape, with single body.
Multi-body and surface based modelling will be covered in future articles.
To recap, the topics and articles links are below:
In this short video you will see some of the powerful live collaboration tools of the 3DEXPERIENCE Platform in a scenario where two designers (Justin and Alex) are working on different parts within the same product.
In this short video, see how CATIA Composer can import native CATIA V5 Composite parts, and preserve all of the Composite Design and Analysis data for use in creating rich 3D documentation.
A simple example of a CATIA V5 Composite part is used in the video, modelled using the 'Zone Approach' with one main laminate and four thicker, reinforcement laminates.
Learn how to open and select the CATPart from your file browser and see how it replicates in Composer, with all the geometry included. You will now have the ability to design and capture multiple scenes (or views) as well as create high quality key-frame based animations.
In this article, we will discuss additional rules to be considered when defining part files. This article closes the main set of modelling methodology for prismatic geometry driven parts, with single body.
This is the sixth article of a series concerning how to implement and use modelling methodology in CATIA V5.
How do you get recognition of your skills or you want to be involved in better work or been seen as making a difference - how do you show your difference?
It’s all about having something unique that gives value to your employer.
Or if when job seeking how do you differentiate yourself from the rest of the pack? I had a friend who said you should draw pretty flowers on your CV! – whether he ever did that I don’t know, but in the competitive world we live you have to have a difference. That’s what sells. In sales jargon it’s called a Unique Selling Point, and when going for a job or looking to improve your position, that’s what you need.
The modelling stage
This is the fifth article of a series concerning how to implement and use modelling methodology in CATIA V5.
In this article, we will discuss the modelling stage in detail.
This is the second stage of the creation process; we already have all the elements defined in the Skeleton group, so now is the time to start modelling the solid geometry.
This is the fourth article of a series concerning how to implement and use modelling methodology in CATIA V5.
In this article, we will discuss methodology and rules for sketch definition.
|Figure 1 - The skeleton geometrical set|
We will continue using the same Angle bracket example part, introduced in previous articles.
In previous articles, we have discussed the skeleton and its internal structure and organization. The subsets are numbered so that the order of the subsets coincides with the order of element insertion, thus we can work sequentially inside the skeleton.
By this point, to start our article, we will consider that we have imported all necessary external data into our part and created all the necessary reference geometry.
All these elements are to be inserted in geometrical sets:
1. Input data and 2. Reference geometry.
As visible in figure-1, sketches are to be inserted inside geometrical sets:
3. Main sketches and 4. Auxiliary sketches, both inside the Skeleton.
The Design Phase
In this article, we will discuss the design stage in detail.
This is the first stage of the creation process; we will create a geometrical set called Skeleton and we will insert additional geometrical sets inside it. The component’s design intent is captured in the Skeleton geometrical set. Skeleton methodology has been around for quite some time now and the idea is to have to model’s main geometrical elements editable from one single location in the part’s specification tree. This also means that we will have many elements inserted inside this geometrical set, so for this reason we will rename them and organize them according to a specific logic.
