Viewport Changes When Layer Turned Off In Current Viewport

[Jeff10]

Hi,

I'm experiencing a problem with the shape of viewports created to display portions of a JPEG underlay, and to mask other portions of it. I am using AutoCAD 2020.

The viewport is created on a layout tab using a polyline to outline the portion of the underlay that I want to display. The polyline is drawn on a layer dedicated to viewports. When the shape is closed I create the viewport using the object menu item for viewports. In this case the layer yellow in color, so the viewport shape is yellow.

Everything is fine up to this point.

I want to hide the border of the viewport, so I select the freeze or thaw button on the layer palette. When I do, a small portion of what should be hidden under the viewport now appears.

I am attaching a Word file with a couple of screen shots explaining the problem a little more.

Note: I get the same result with the changing viewport shape if I select freeze or thaw for all viewports. If I choose to select turning off a layer in all viewports (versus freezing) the shape of the viewport does not change.

I will end up turning off the layer in all viewports for the six layouts once they are complete. I just want to know if I am missing something that would make the freeze/thaw work on individual layouts.

Thanks,

Jeff

If I may ask, would the problem remain if your viewport layer was just set to no-plot like most of us AutoCAD users do, and left it on/thawed all the time instead? Gives you the same PLOT result as freezing that layer.

Layer Freeze&Thaw removes object from the editor object list, the objects no longer recognise for calculations

and not visible.

Not there, means also that there is no vpclip(while the layer is freezed, so the whole (always rectangle) viewpotr displaying your model-content, jpeg, lines, all.

{the VIEWPORT objects acting different, it does its job even if the layer is frozen, but that's an exception in the system and does not apply to other objects.}

Ther right way to hide the viewport from plotting (and that's the only useful reason), is to use a non-plot layer ay Pendean already said.

>>"turning off a layer in all viewports (versus freezing) the shape of the viewport does not change."

Layer OFF just don'T displaying objects, but they still there, you can edit & delete those objects,

that's why the shape doesn't change: Your vpclip object is still there (just invisible).

The difference of Layer properties ON/OFF and FREEZE/THAW,

also important for blockreference and nested items in blocks.

Hi Everyone,

I know there are standard ways to keep the viewport layer from printing. 

Understanding that the viewport must be a rectangle answers my question.

Thanks for the explanation.
