Different position of the cursor giving two different Extruded result. When I touch line by cursor all body gets Extruded. When I touch point by cursor narrow strip between two sketches gets Extruded.
What is the reason for that?
Use the selected contours tab
and chose contour you want
You have two closed loops and SW isn't sure which one or both can be used.
All body is extruded for the line. Narrow strip is extruded for point.
What is the reason for that?
See above response. You have two closed loops and SW doesn't know what you want to do so they give you the choice. I haven't seen the picking line vs picking point before but that makes some sense and I just tried not selecting the sketch first and then selecting the extrude command and then selecting either the line or the point and I get what you've shown.
So, see above response :-)
You can select the sketch or the selected area between the sketches.
I found there was no response when I selected area between the sketches.
That is the way SW teaches it. Again, you have two closed loops, an inner and outer. Either one or both can be selected in order to complete the operation.
Technically speaking there are three closed areas.
-One is created by big sketch
-Other one is created by small sketch
-Other one is created by strip between two sketches
How to tell SW which area we are interested in?
Thank you very much for your help.
That's not really an answer to your question but oh well.. Glad you got figured out
Could you tell me please what was your understanding about my question? If it has any other meaning it can help me to learn unknown things.
I saw, "What is the reason for that?" and reacted to that.
The reason for the two different regions being extruded is what I answered to. SW allows you sketch multiple closed regions (loops) with in one sketch but it doesn't know what you want to with them. Most of us have learned SW with a workflow that says when you're finished with the sketch just select the extrude feature and what you've found out is that when you deselect the sketch and move into the feature that SW has given us another method in selecting with region will be used in that extrude.
I didn't know that was possible because I always use another method bu it's cool to find new ways to do things.
If you want to extrude outer part click cursor on big sketch.
If you want to extrude inner part click cursor on inner sketch.
If you want to extrude strip use contour dialog box and click cursor on both sketches.
My problem was solved but not clear about why point is extruding the strip. And another problem is sometimes Extruded Boss/Base command automatically extruding the strip without any indication, it happened to me.
I found it was unnecessary to know why Point was extruding the strip.
What Ned pointed out earlier was that the normal way of selecting the closed loop (contour) is to select that space on the graphics screen inside the sketch profiles that make up the regions.
I'm guessing when the point is selected SW recognizes it belongs to the outside profile of the sketch and therefore shows you what it (SW) thinks you want. Like I said, that's cool but most of us were taught to select the inner portion of the sketch profile as the contour.
