I doubt if the "Curve on Plane" function has been deleted, the terminology may have been changed though. If a surface has infinite maximum & minimum radii of curvature (or zero curvature in any direction) — then effectively it is a plane. So, try selecting the Surface option to construct a...
I assume the method of importing points from an Excel file into V5 is still available; search the online Documentation for "Creating Elements from an External File" — it gives an explanation of how to create points, curves and simple surfaces from a file of X,Y & Z data. Search the Help...
Meccano set, 1950s — click the picture for the link to the history of Meccano
In the early 1950s I was given my first Meccano set — and I'd be pushed to think of a better present that fits the requirement for an "Engineering Christmas Toy" than Meccano. It was first sold (here) in England, over...
Nearly 27 years ago I had a full week (about 50 hours) of one-to-one Catia training on Version 1; it was provided by a IBM senior software engineer who knew Catia inside out. I can't think of a better way of learning Catia — I was very fortunate. During the next few months this IBM engineer used...
I've modified my Basic subroutine to deal with the intersection point case — by a different method, and what I think is far simpler than before. It's all done in 3D using direction cosines: it uses no auxiliary axis system, no transform matrix, no rotations, and no plane equations.
The centre...
Finding the centre and radius of the circumscribed circle of a triangle (ABC) is something I first did in the mid-1980s — in BASIC, I'm retired now but I've still got the notes written at the time. The normal form of the plane equation wasn't used — just the direction cosines of the axis system...
Snail Shell surface
Well, thanks for the suggestion, ferdo - and I've certainly got plenty of time - but I don't have access to a V5 terminal anymore, as unfortunateIy I'm now in my late 60s - and retired. So, I'm sorry, I'd like to contribute something reasonably constructive to the thread...
It seems to me that this particular Law method of making the involute of a circle is unnecessarily complicated - and not the best way of constructing an involute (in this case, of a circle) in V5. What appears to be happening is that two component plane curves - x(t) and y(t), shown as red and...
Constructing a curve from an equation is something I do using the Excel file method - it's very fast, and it's easy to edit the code and re-run it. In the Help documentation a search for "Creating Elements from an External File" describes the process. An in-depth knowledge of VB is not really...
The spring can be considered as the trace, or locus, of a moving point — therefore it has a starting point — and that's the first thing Catia asks for. So, it is at the radius distance away from the centreline, and it's going to wind along and around the line. The Pitch should be...
I also agree with Ferdo; this isn't really the place to come for basic training. I'd recommend you talk first to your manager or whoever you report to - and ask to go on a proper V5 training course.
Has your employer invested in Catia; but not budgeted for training the people who are going to...
An interesting case, and not uncommon - it's the last bit that's the problem. There is very little to work with: 2 planar curves that appear to be concatenations of circular arcs. The finished part looks as though it is one half of a neutral airfoil.
It's probably safe to assume that a section...
As is often the case there's more than one way to make this surface. I've tried some of them and here's the results. Apart from one, they looked identical but when analized there are small differences in area. If the first one is considered as having unit area then the others are:
(1) Blend -...
Earlier this year I wrote about Laws and their application here. Try looking in these two: Thread560-176891 and Thread560-191644
I'm sure there's no need to use Adaptive sweep for what's described, or to try and do it Sketch: it's all there. As Jack says, use the, misleadingly named, Parallel...
As solid7 says, a transform is needed. For the new axis system click Insert => Axis System. This shows the Axis creation box, and in front of it is the transform box (Axis to Axis).
Although, I thought the CMM Controller might have had some facliity to do it - if the QA guy was given the...
Thanks Jack, I didn't realise anyone would keep a copy of that stuff, so here's a summary of the last lot.

My first thought on reading this was to make the the die in (at least) two pieces, probably six. I've just looked in one of my old books (Die Design and Diemaking Practice by Franklin D Jones, 1941) and there is a complete chapter on split, or sectional, dies.
This is gist of the first page:-...
This is a guide to how I put images in posts, I'll start off with a single picture, then the so-called thumbnails and finally using links to pictures. This procedure applies to any of the Eng-Tips Forums. Upper and lower case is allowed, it doesn't matter which.
Before anything else the picture...
