General:
To import you need the "Part Template" tool. This can create some 3D points in Catia V5 from their coordinates stored in one Excel file. The created points can be automatically renamed if the name information is available in the Excel file. An optional feature allows building straight lines between every point.
If you want to know details, please check the document below.
The tool that you have to use is a "Power Copy". To use it, a Part must be activated. If you want to know more details, please open the document which is under.
The following document has an explanation how to do this step by step. Please check it if you want to know more.
The "Surface Curvature Analysis" is used to find the curvature of the surface or the face of a solid. You can perform analysis in "Part Design" as well as in "Generative Shape Design". If you want to see how the procedure should look like, please open the document below.
Split is an operation where one element is cut by another element.
Trim is an operation in which two elements cut each other mutually.
If you want to see more details and differences between these two functions, please check the document below.
To get the surface from land contour lines you need to proceed from the isolation of the relevant geometry, then the improvement of the quality of the geometry and then the generation and extraction of 3D points. Then you should transform the 3D points into the cloud of points, generate a mesh and then finally auto create a surface feature. If you want to know more details about it, please follow the link below with explanation.
Distance analysis tool could be used to measure distance between surfaces which are very close to each other. The distance is computed in several points so as result we will get the distance distribution between chosen surfaces. You can find "Distance Analysis" tool in "Shape Analysis" toolbar which is available in “FreeStyle” workbench. To find it, follow the instructions on the document below.
You can now create planes between two existing planes at once.
Follow the instruction to do this:
- Click on the "Replication" toolbar.
- Find the icon "Planes Between".
- When the dialog box appears, select two planes between which the new planes must be created (it cannot be parallel).
- Indicate the number of planes.
- Click "Preview" to see the plane created.
- Click "OK".
- Planes are added to the tree specifications.
For more details, please check the document below.
For objects with features that are symmetrical in the thickness direction, a middle surface can be created using functions from the Generative Shape Design (GSD) workbench. There are several options on how this can be done.
In the following document you can find three scenarios that a user can basically come across:
- All of the object’s relevant features are symmetrical in the thickness direction.
- Some of the object’s relevant features are asymmetrical in the thickness direction.
- It is possible to create the solid from the surface rather than the other way around.
To know it better, please check the methodology in the link.
A 3D curve can be created in space or lie on a geometrical element, or both. When the curve lies on a geometrical element, associativity can be kept. It is also possible to edit, delete or add points when creating the curve, or after. A 3D curve is a very fast and flexible tool which is really different from a "Spline".
- route electrical wires,
- work with Bezier Nurbs,
- create a guide curve for a sweep or a rib.
From the following document, you will learn new possibilities about 3D curve from "FreeStyle" workbench.
The 3D curve function is available in the Freestyle workbench. With the 3D curve function, it is possible to create associative curves in which you can add or remove points during the creation of the curve and also later.
If you want to know more details, when to use it or how to modify it, please check the document below.
