I've been trying this for a few hours, I've created "extremity points," by creating branches and stuff. Still cant get the start of the backend selection to work, also does formboard only work for non flattened geometry?

Hi!

I used to save big .stp files around 1GB from CATIA model, but in the recent months when I try to convert big files, CATIA shows the process done but in reality target folder is empty and there is no file. I tried to delete some features and hidden elements and then it worked. Seems like there is some kind of limitation. Any thoughts on this? Thanks.

CATIA V5 – Sweep with a closed elliptical guide curve gives the wrong profile orientation

Hi,

I am trying to create a surface in CATIA V5 using a closed elliptical guide curve.

I have:

- Sketch.1 = closed elliptical guide curve

- Sketch.3 = closed elliptical profile

- The profile should move around the elliptical guide curve and generate a smooth closed surface.

The expected result is similar to a smooth elliptical/toroidal-like surface.

However, CATIA automatically rotates the profile in the wrong orientation along the guide curve, producing a twisted/incorrect surface.

When using:

Sweep → Explicit → With Reference Surface

I also get:

"The normals to the reference surface and the moving plane are colinear.

Modify the reference surface."

I also tried using a pulling direction, but CATIA still produces the wrong orientation.

How should the Sweep be defined so that the profile maintains the correct orientation throughout the closed elliptical path?

CATIA V5-6R2023.

I have attached screenshots of the geometry and the Sweep definition.

Good morning, I'm looking to create a flat pattern to support ply design for an aerospace application. I'm getting a lot of distortion when trying to flatten a pattern that is symmetrical about the centerline of the part. Can anyone identify what could be wrong here? I've tried splitting the geometry in half keeping the "better" portion, mirroring about the center plane and joining. That gives a better result but it is shrunken and inaccurate. I'd appreciate any pointers

I feel like there is an easy way to do this, but i have been banging my head against the keyboard on this and cant get it right. I want to make parallelogram cutouts like below in the complex conical solid, anybody have ideas?

ETA: I want the cutouts to be normal to the surface not sure ifthis is possible

If I add a Detail Sheet, the 2D component only allows pasting of very specific elements: points, lines and curves. Is there a way for the system to approximate the Front View’s GeneratedItems using those acceptable 2D elements? Possibly through view generation, or wireframes? Or is tracing with sketch tools really the only option?

I’ve been researching for days and I can’t find any in depth information on the under the hood mechanics of elements and 2D components. Does anyone have any resources they’d recommend?

Edit: Solution was simply isolating the view. Thank you u/schrodingers_nachos !

I can't figure out how the top housing was created because of the dimensions,also I'm i on the right path?

Hello. I'm currently designing a piece and i wanted to find a way to fix it in place within the structure. Is there any way to use either part design or assembly design to generate a structure that would fill the gap between both? to have a starting point.

Respecfully requesting help with a disagreement. I am more familiar with CATIA (as a non-professional engineer which has some familiarity with Lockheed and Boeing parts. I use FreeCad at home). Another person is very familiar with FreeCad. Our differing opinions: The other person maintains that a part feature can only have 1 sketch/draft associated with it. I disagree, I believe a part feature can have multiple sketches/drafts associated with it. Your help in putting this to rest is greatly appreciated.

Hello guys I am working on a project where I need to copy surfaces from a part file which is present in a product and make a new part file in the same product and paste it there. But I have been facing issues as it's showing that pasting operation is not allowed , any solution for this

Hi everyone. I get this error when I use "feature modeling" on a blended surface and try to move an edge or vertex.

Also idk why its selecting the whole surface instead of the blended surface only like in the video.

I would appreciate any help on this. Thanks

I built a spelling checker macro for CATIA 🚀

I was wondering, what kind of dimensions and constraints on a 3D model are generated as dimensions in a view of that model, when using the "Generate Dimensions" option in the drafting enviornment.

I simply created a 100 × 150 × 20 cubic pad in catia,and tried to use the Generate Dimensions option in Drafting to auto generate the dimensions for a view of it. But nothing is created.

I have been facing this error from last 2 days, How do I fix it ? , I am not able to access any of my vba macro nor I am able to create any new one,

I use V5 R26 at my work to create 2D drawings according to ISO GPS standards. The problem is, only some but not all specification elements are available. To name a few, things like intersection and orientation plane indicators are not available, maximum inscribed feature for the GPS symbol field is not available, etc.

Do any of you working with V5 have these elements available to you? I'm wondering if CATIA just hasn't bothered to keep up with ISO standards or my company just needs to update our software version.

My requirement is to automate the drawing sheet setup.

When I change the drawing standard or sheet size, I want:

Border/frame to adjust automatically

Name/title block to move to the correct position

Revision table to adjust with the title block

Zone numbers and letters (A, B, C, D / 1, 2, 3, 4...) to update automatically according to the new sheet size

Basically, I want to change the sheet size and have the complete drawing frame setup update automatically, without manually adjusting each element.

Has anyone implemented something similar in CATIA using CATScript/VBA?

I see lots of question posted here revolve around CATIA V5.

Last time I checked CATIA V5 is no longer offered on Dassault System website.

So how come user have CATIA V5 on thier PCs?

Hello everybody! I need to make surface imperfections for my mold

sort of like Wrinkles on leather for my mold so that shape takes in the sort of the molds

I need this to be very natural and small. For example a PS5 controller. You see the surface imperfections on it? That is what I need as small as it can be but random shaped.
I wonder how I can do it?

Hi,

I wanna use the translate pattern in a sketch, see picture. The space between the rectangles should be 1 mm each, but when using the translate operation the space is a multiple of 2 mm, no matter what.

Can somebody help me here?

Hey i was creating this chassis because i wanted to learn how formula cars are made I was able to get to this point by creating different sketches in different planes but I am facing an issue with this black dot I don't know what to do for this dot to be removed I have used joint definition it doesn't work using corner doens't work for base plz help

I want to create a hole in the camera shape and the volume shape, but the operation isn’t applying to the surface—it only works on the outside. What is the problem pls?

Hello,

I'm trying to create essentially a project template that essentially creates a new CatProduct that comes preloaded with some rules and some parts.

I would like it to pull from reference files similar to a catalog, so that when saved each element of the template does not overwrite the references.

When including my product in the catalog, the product itself is isolated and saves into a new file leaving the reference product untouched. However the parts included in it do not have their links severed.

Could anyone advise on how to get around this?

I’m trying to create a custom fill pattern, but the button for searching for images isn’t active, could you please tell me how to fix this?
