Disjoint contour - base extrude - ??

Disjoint contour - base extrude - ??

Disjoint contour - base extrude - ??

(OP)
I am using 2001
Have imported a sketch from a DXF file.
Doesn't matter what I do I cannot base extrude as I get the disjoint contour message.
Even when I do a sketch , by hand ( not in any way linked to the imported sketch) I get the same message. Each time it tells me that a different contour ( usually a straight line )is the offending contour.
Can someone explain to me where the problem is?

Thanks

RE: Disjoint contour - base extrude - ??

disjoint contour means ur sketch has multiple disjoint profiles.( some gaps or some extra profiles intersecting or overlapping the same sketch itself)
for solid extrude the condition is, the sketch should be closed profile and non overlapped profile.(except from thin extrude)

check that sketch has any gaps in between or not, overlaped etc. . for checking sketch,
 select- tools- sketch tools- check sketch for features.. from this it is highlighting where the sketch has problem. try to connect the gap and solve the overlapped portion. then try extrude.

i think , this may solve ur problem...
thanks,

RE: Disjoint contour - base extrude - ??

If you are coming from an ACAD background one of the things to be aware of is what ACAD allows you to do (that you shouldn't). One of the most common problems of this type is multiple object lines laying on top of each other. SolidWorks will not create a feature from overlapping lines, but ACAD doesn't care.

If you go into Tools > Options > System Options then go to Sketch and check the third box to "Display entity points in part/assembly sketches" you should be able to see the endpoints of the lines when you are in the sketch.

Let us know what you find out.

I'm not sure if SWx 2001 had this option, but try this:
Go to your Tools pull-down, then Sketch Tools, and see if you have an option called Check Sketch for Feature.... If so, select base-exrude form the pull-down and hit the check button. This will show you where the problems in your sketch lie.

Thanks All but I have not found the problem.

I have often used the "Check Sketch for Feature". It highlights a particular line. I delete the line, redraw it,ensuring that it traverses the space from endpoint to end point, and still get the same error.

Dennyd - I have turned on this feature ( Display end points-thnx )but all it shows me is that the line is fine.

Yours, ( still stuck )

GREAT .... so .... what was it & how did you find it ????

RE: Disjoint contour - base extrude - ??

(OP)
Well as it turns out the imported file had two distinct disjoint contours.
As a new user of Solidworks....I had completely forgotten that this program could not extrude two completely seperate shapes - a problem aparently fixed in SW2003 or 2004.
The problem was that when getting the "disjoint contouyrs" message it di not highlight one of the sontours but one straight line from one of the contours - indicating, to me at least, that there was spomething wrong with that particular line.
Nothing like learning the hard way
