Find Cross-section problems?

[tlehnhaeuser]

I often have to create 3D from very abstract art. attached is an example of one.

The issue is it will not extrude. Troubleshooting for cross-section errors is almost impossible. Anyone have any tricks to find the errors with the cross-section?

 

thanks

If the Clear Duplicate command doesn't find anything, start zooming in, hunting also after the cross section fails if you hit Edit you can go back in and it will usually highlight purple the bad area, here's a few areas to start with:

Hi Tom,

 

Yes I understand the difficulty in these cases. If you extrude, create a default shape, edit the sketch, it will show the overlap areas but they are difficult to find if you have the points on. Right-click and select Show and turn off All End Points. This will help but is still difficult to see in general for the purple overlap curves. We can file an ER to possibly highlight or move to the curve areas.

 

In this case there are three overlaps. Two from one profile in the middle bottom and one on the right bottom area. Check the area in the image.

Sorry, no trick that I am aware of. Same as above.

Thanks Everyone. I wasn;t away fo the "Clear Duplicate" that didn;t work as stated but still I can see that one as good to have for the future.

 

I dont get any purple highlights, so yes if an ER to highlight them better!

I always search for these possible issues:

 

¤ Overlapping Curves

Remove by using the Clear Duplicate tool.

 

¤ Crossing Curves

Highlighted in purple when you Finish.

 

¤ Red dots 1 = Open Outlines

Outlines must be connected = white "knee points".

 

¤ Red/White dots 2 = Zero-length Curves - the hardest ones to find!

Select the outline, Cut (or copy).

Then Select All (easiest by hitting [Ctrl] [A]).

Delete everything.

Then Paste back your outline.

I fight with that too!

....often!

 

Here it would be nice to see it better.

 

Often I cannot find the problem, means wrong lines.

 

Maybe an extra highlight would help. "Glow wrong"

Or: Suppress the working / good curves...so we can only see the problems?

Or: Show it by circle around it

Thanks Jonas,

You that's my list too, accept the clear duplicates that I wasnl;t aware of.

Tom,

one last method I use to troubleshoot issues on the sketch, is using the outlines list within the 2d cross section properties dialogue.

While in the sketch, right click and choose, Cross Section Properties, and then Outlines.

Drop the combo box down and in the example shown it lists 6 outlines. the first two are always the X and Y axis. So I have four present. This way you can track down any troublesome entities.

Now this is probably not going to help with your example, too many to count !

Very Interesting approach, thank you!
