All, We have a design that is in effect a face to face 'O' ring seal. The client requirements is that the faces are inconel coated. What is the requirements for inconel coating? i.e. The 'O' ring grooves will have to be oversized, coated with inconel and then re-machined. How thick is a typical...

All, To achieve a certain clamping force between two friction faces (or bolted connections), is there a requirement of a certain bolt length to provide enough bolt stretch to hold the connection together. i.e. For 1" bolt connecting two faces, do you require a minimum nut seperation length to...

Guys, Consider a pipe of 100mm OD and lets say this is subject to a maximum ovality of, say, 10%. Taking a section through the pipe, does this mean that: 1) The pipe can be 110mm in the x-plane with 90mm in the y-plane? 2) The pipe can be 105mm x-plane / 95mm y-plane? 3) The pipe can be...

Seant, that is exactly what I am trying to do. Only difference is that the seal shall have a square profile and a seal groove to suit. So, can you tell me how to do this? Thanks.

Guys, I don't think I made myself all that clear. I need to draw an elliptical 'O' ring. Imagine and 'eye patch' on the outside of a pipe, hence a piece of rolled plate taking say 80-deg of the pipe's circumference. Within this eye patch is an 'O' ring groove. Can AutoCAD model a circular seal...

Currently trying to model a rolled plate to match the exterior of a pipe, similar to a repair patch. Problem is that the patch will have an 'O' ring groove machined into the mating face of the plate, machined prior to rolling the plate. Is it possible to configure AutoCAD 2007 to produce an 'O'...

We are looking at designing a pipeline clamp to hold 2,500psi. An area of the 16" pipeline is question and we have been approached to design and manufacture a twin half shell clamp that can be placed around the pipeline, clamped & squeezed together to contain the pressure. We are having...

The concern is de-lamination of the plate in this undefined direction. This seems unlikely I know and I have never came across it, but mill certs for steel plate only give X & Y direction properties (Length & Width on the mill), but not Z direction (Thickness). Apparently steel with impurities...

thanks Todd, that's fixed it! Kev

All, When you print cylindrical shapes as a 'Hidden' viewport in paperspace the shape prints with lots of diagonal lines on the cylindrical face. Is it possible to turn this off this feature?

We have a steel structure that we need to attach some lifting padeyes. Where these padeyes will be attached is loading the steel in it's non prefered direction (Z-direction pull). The material certification doesn't cover Z-direction tensile testing. The remainder of the structure has been...

I would tend to try turning the boundries into polylines using the PEDIT command, turning one line into a polyline then choosing 'Join' to connect all the other boundry lines. You will find most of the lines with stick together and where it won't connect with the next line is where the break is.

Using AutoCAD 2007 full version.

Probably something that has been covered many times, but in paperspace views can items that are hidden be shown as hidden lines i.e. dashed lines?

I have resently fitted a larger engine to my 4wd (light weight alloy petrol to large heavy diesel), increasing the front end compression on the coil springs. The car now feels a little 'sloppy' in the rear end and I can only imagine that this is due to the heavier front end. All mechanical...
