Make 2D & clipping Plane

[2DCube]

When looking at the clipping plane the model shows a rendered view rather than shaded view?

Also, when using a clipping plane and make 2D the result shows faces but not capped solids as it shows within the viewport:

@GregArden
Is this on your YouTrack list?

[GregArden]

Yes, Its toward the top of the desired features list.

[jeffoulet]

Hi, sorry to revive this fossil thread, but… what the stand on that feature?
It seems that Make2D still handle some edges as ‘Visible’ even if they’re behind the clipping plane…

[John_Brock]

I do not see the clipping plane graphic in your screenshot.
Please post a file with that geometry.

It’s working as expected here:

[John_Brock]

It working fine here.
If I move the clipping plane to clip off more of your box and run Make2D, I get a shorter 2D result:

[jeffoulet]

Ok, but in yours, the ‘inner’ edges appear to be on the ‘hidden’ layer, like if the clipped surface was filled (like cutting a real solid):

This is also the behaviour I’m looking for.

In my model, the inner edges are treated as ‘visible’ (like cutting a hull):

[jeffoulet]

I get the same output with your file:

Edges viewed through the clipping plane are considered as visible.

[John_Brock]

Your linetype scale setting is too small.
In Options > Linetype, change the line type scale to 200 or higher.
Your lines are using the Hidden pattern but your scale is so small you can’t see them.

[jeffoulet]

Humm, not sure it has to deal with linetype, please see here, the selectionned segment is really on the ‘visible’ parent layer:

[John_Brock]

The Hidden linetype pattern is defined as a line 2mm long followed by a gap 2mm long.
Your linetype scale was set to 1.0
The section of hidden line is 15761.85 millimeters long.
Divide that length by 2 and you still have a lot of tiny little dashes you can’t see on your monitor.
Change the LT scale please

[jeffoulet]

I increased the LT scale and I now see dashed lines. Unfortunately it was not my problem. I think there’s misunderstanding in the air

1 - what I get out of Make2D: inner edges are on the ‘Visible::*’ layers
2 - what I want: all inners edges occulted by the clipping plane to be on the hidden layers:

[John_Brock]

If you uncheck the Hidden lines option in Make 2D, the the visible surfaces will occlude the surface edges and curves behind them.

[jeffoulet]

3 - the result with unchecked ‘hidden lines’ by Make2D, still hollow representation:

[John_Brock]

It looks like your Clipping Plane is slicing off the front face of the box in 1 and 3 so you can see the insides.
2 looks wrong to me.

[jeffoulet]

But 2 is exactly what you get in your example:

[John_Brock]

I had my Perspective view rotated around so the clipped off surface is on the back, away from the current view.

[jeffoulet]

OK, that’s an explanation. So I understand that the original wish of this thread (capped solids while performing Make2D sliced by a clipping plane) have not been implemented yet.
