Every time I use the cross section tool (I marked it in the file attached) the result is a incorrect drawing. I mean there is no dashed lines at all!! Every drawing I create (using this tool) is unusable. I'm just wondering is it a bug or intentional solution.

Check the line type scale, are you using object color when you do the model to sheet.

The scale of lines is 1.0 but the type is wrong. It should be DASHED in pen's setting in inspector window but it's not. What you mean do I use object color when I do model to sheet? I use "black" in solids and lines.

Hi Magicart,
Your Section View shows the same information that displays in
the view in the upper right of your page.
I use Third Angle Projection, and this is just my opinion,but
I would Section the Right Side View to show the interior.
The lines that are not displayed as dashed are another issue.
Again, this is just my opinion.
Larry

Hi L.Banasky,
thanks for your comment. I'm aware the section view I uploaded is essentially worthless and you're right that better is to show right side view instead of this. I created this view just to show the problem with a projection.

Hi Magicart,
If you left click on a drawing view, and then right click, a menu will let you select 'Properties'
'Use Object Color' for 'Hidden', and they will show up in the view.
Select 'Ignore' and no 'Hidden' lines will show.
By the way, 'Hidden' lines are very seldom used in 'Section Views'

Hi Larry,
I did exactly what you told me, but nothing changed - still no dashed lines in a cross section view. More, any type of line I choose from a "hidden" menu in the "properties" window the result is no change. I noticed that this reaction (no reaction de facto) concers only cross section view created using this single tool - I marked it in a first post! The rest of tools from this pallete create views correctly.

Hi Magicart,
The only other way would be to select each line, and change the properties
using the 'Inspector'.

In the drawing I sent the hatch is not shown - it should be displayed as hidden - so it must be a bug

And just to make sure I understand the standard correctly, if the hatch is shown, than it is shown as solid?

Best Practice with section view is to leave out all hidden lines unless using them saves another view from being drawn. The section view should contain all visible edges / contours behind the cutting plane. As this practice was used when drawings were done by hand.

A section view purpose is to best represent the feature/geometry that would be shown as all hidden lines in a standard view and hard to visually understand.

I would say this is hard to implement rules in cad where views are auto generated as there are cases where some geometry is needed to be show in a section view, and could contain some hidden lines to describe this feature without the need to add another view.

In my opinion its easier to leave out all hidden lines from features not visible from the cutting plane as a general rule, for those lower percentage cases the geometry can be drawn or use more section views or offset sections to define the features as its auto generated.

Regards

Jason

Hello Tim,
Because of my English maybe I wrote something stupid so let me explain again. There is a single bug connected with a vertical section tool only. The bug is the auto-generated section does not contain hidden lines - I know, in most cases we dont need hidden lines in a cross section, but sometimes when there are contours behind the cutting plane these should be represented by DASHED not by SOLID. The vertical section tool show it always as a SOLID. To prove that it's a bug I uploaded a file where you see two sections which should be identical (I did it in the same area of a model). The first section was made using break-away tool and this is OK! The second view was made using vertical section tool and this is a bug because there is no hidden lines.

Hello Jason,
The practice you mentioned I agree 100% with you. I created this geometry just to show the bug. I use cross-section views without hidden lines mostly but if there is a possibility to fix then I report.

SharkFX build 1191
PC running Windows7 64

I have a series of screen shots using the Vertical Section tool cutting thru the center
of my assembly showing the different affects of toggling the different pen styles in the
Draw View Properties dialog box. The first screen shot is with all the pen styles ignored,
so should there be lines in this view yes or no. You can see the results of each change to
the pen styles in the different screen shots.

Can this be Fixed?
