lines projected from a solid body don't always behave as continuous path

[maker9876]

Quite often, when projecting a solid body into a sketch, find that lines which were projected from a continuous surface don't exactly behave like they are all connected.

Have noticed this in two ways:

1) If one tries to make a surface to extrude using various projected lines, well that's not possible. As a work around start drawing lines to divide what should be a surface into areas to find out where the hole(s) is. Fix the hole in the projected lines by adding lines manually of my own.

2) If wishing to sweep a profile along the projected lines, find that cannot select all of the lines because there is some kind of discontinuity.

Anyone else noticed such things? Are there any tricks?

Hi @maker9876 ,

Thanks for posting your question.

In this case If you provide some more details then its easy to us help and reproduce this cases.

If you have any image file or screen cast then please share those details for further investigation.

OK. Here's an example.

Please download the file quickly because would perhaps like to continue to work on the design today.

If you navigate to the component "case_LEFT:1" there's a sketch called "path to sweep". Notice how the sweep function stops at a certain point on the projected line and the selection cannot be made to go further?

Like I said in your other thread you have lots of double and sometimes more projections. These dirty sketches are going to produce bad surfaces like the face you're trying to use seems to have been made off several projections and extrudes. You can get the sweep to work better if you use the edge of the solid but I think you're building a house of cards here. Really don't know how you've ended up with all the bad sketches from projections.

Here's using the edge of the body instead of the sketch.
