View Orientation in Section / Elevation

[ShaunTaylor]

Hi,

Bit of a strange question. Is there some kind of global variable I can use to determine either which way a section / elevation is looking or the orientation of my object, in relation to the section / elevation I have open?

To give some more context. I have written a poly_ (0 thickness) command in the 3D script and I would like to hide the poly2_ command if my section / elevation is looking at it from a perpendicular direction. You will see an example of my issue in the images below. I would like to not execute the command, when we are looking at it side on to hide it.

If anyone has any good workarounds, I would be very grateful. Thank you.

Not that I am aware of.

As far as I know, all you can do is determine if it is or isn't in a section/elevation.

All I can suggest is to model a thin white zero thickness poly with no perimeter lines rotated 90° to your object and placed at each side to mask it.

I am not sure if these would then show up as a line from the front, or if with no perimeter line, they will be invisible side on.

Related to these threads, which do not have a solution:

Would be nice to know the angle of a section or elevations...

@Barry Kelly using white lines may be visible if the symbol overlaps a relatively dense fill, or coverfill.

Yes, I know.

You will either see the lines or possibly the small white fill.

Pick the better of two evils.

You will have to see something if it is in 3D, unless you can turn it off by layer or renovation filter.

I am petty sure there is no way to determine the angle in relation to the elevation.

I have used model view options for this purpose. You must define the view angle for every view.

The object reads the viewangle from the mvo and acts respectively.

Of course You have to have an object for MVO.

[Barry Kelly]

Wouldn't that mean that you would have to duplicate each MVO combination (scheme) that you use so you can set a different elevation angle in each one?

For example even if you had just two MVO combinations, (one for detailed windows in 3D and the other for simplistic windows in 3D), and you simply have an MVO option that turned the object on or off, you would now have to have 4 MVO combinations?

Usually 4 options , depends on how many projection directions are in use.

[ShaunTaylor]

I have contemplated all of these scenarios, including MVO's. The disadvantage is that it makes the workflow for my team a bit complicated.

Interestingly enough @Barry Kelly  the masking fills around the sides of the symbol with no edges may do the trick. I tested this and seems to look acceptable. I enabled to show in 3D to screenshot the result for you. I am satisfied that fill will not print or change the lines on the drawings.

Excellent.

You could make the side fills much narrower, as they only need to hide the side on disk profile.

That would work when you are 90° to your object.

And if you are at another angle (say 45°), you wouldn't be masking half of the object.

It may also save you from having to use display order if you do have hatches on elements in the background.

Yes I agree, I had them temporarily exaggerated to show the result. I actually have them super thin and they still mask the line which is good.
