I have a sketch that I am trying to revolve. When I go through the motions and get the revolved piece, it is slightly offset from my sketch. I have no idea why this is happening.
If anybody has any ideas that would be very helpful.
Move your image quality slider to all the way to the right.
Welcome to the forum.
You should be able to window ans select the entire sketch and select this command
to rotate it.
I am assuming you mean reotate instead of revolve.
I'm referring to revolve under the features toolbar. For some reason it shift my sketch to the right a half mm or so before it revolves it.
It sounds like it may have something to do with the sketch line or axis it's revolving around. Can you post your part?
Sorry for confusing this.
Where is your sketch plane in relation to where you want to revolve?
Could that be slightly offset? Or possible that the location of your revolve axis
is slightly offset as well?
I didn't offset my sketch plane at all, it was the origional plane.
IT may be that you revolved it as a thin feature. Can you post an example?
I made sure to turn off the thin command. One pic is the offset revolve and the other is the dialogue box for the revolve itself.
If you measure the edges that look shifted do they measure correctly? Also, if you create a new part and create a revolve do you get the same behavior?
Rather than play twenty questions, can you post the part for review?
Make sure you're fully defining your sketch (especially when revolving). I've seen under defined sketches do things that are not intended because they aren't controlled. Hope that helps! Is your revolve axis on the same plane as your sketch?
Did you make any of your dimensions relative to a silhouette edge by any chance? I've seen revolve weirdness like that happen when silhouette edges are used as references.
Yea, all the edges measure correctly.
Dan, what do you mean by sihouette edges? Like construction lines? Because the line im revolving around is a construction line lined up with the origin.
A silhouette edge is the edge of a cylinder if you look at it in 2D (as in your sketch). Essentially it's an edge that doesn't exist, but SW allows you to use it as a reference for some reason.
A Silhouette Edge is the outline of the part as would be shown in a 2D drawing view.
I would guess your plane you are using isn't aligned the way you think it is, you may want to check your plane orientation in relation to the actual location you want the feature.
I suppose that's possible. But i didn't make any alterations to the original plane, so I don't see how it could have gotten misaligned.
if the plane is a surface of another feature it may be at a different angle relative to the horizontal or vertical axis of your revolve. This is something i would walk over to and tell the person to send me the model so i could tell what exactly is going on.
Sounds like posting the part is the best move. Unfortunately it's for a client and is confidential. Thanks for all the tips, they are very helpful. I will post the solution when I find it.
Im actually building the part by referencing a finished version of the part, both on the same program, but one works and the other doesnt. So I cant imagine it would be the graphics.
I tried fully defining the sketch but the same issue happens when i complete the revolve. One weird thing is that the 'thin feature' box is always checked and I have to uncheck it in order for the revolve to work... Maybe this has something to do with it.
I completely take it back. It was the image quality. I had no idea that could make the part look so inaccurate. THANKS!!
SolidWorks cannot display any curved surfaces. So what it does is break them into triangular surfaces. This slider controls the size of the triangles. The reason for the option is for the varied video cards used. The more triangles, the longer it takes to refresh the screen. If you have a weak video card and llots of triangles, you will have a lot of lag when you rotate you model.
I'm glad the problem had an easy fix, but for future reference, you could make a copy of the part and delete or change the features so that it bears no resemblance to the proprietary part, or just create a new non-proprietary model which exhibits the same problem.
I appreciate the advice, thank you.
