Model dissapears

rpreston513 — Tue, 06 Oct 2020 20:53:36 GMT

I'm using AutoCAD LT 2021. I'm editing a drawing created by someone else. Both the model and layout are in MSPACE. When I select anything (or everything) in the layout and convert it to PSPACE anything that was selected disappears from the model. Scaling doesn't seem to help. Zoom-Extents doesn't help. What am I missing?

Thanks for the file: I see a diagram and titleblock in modelspace, and in paperspace I see an unlocked viewport looking at the that content with the cursor inside the viewport. There is nothing else in paperspace other than that viewport.

All of this is normal: so what exactly is the issue, do you knot know how to exit a viewport in paperspace?
Do you wish to not use paperspace? Are you trying to resize the viewport?
Are you very new to the concept of paperspace? or AutoCAD in general?

Please elaborate so we can best help you based on your experience level.

TIA

Are you using the chspace command, because that is what it does it moves everything you select from modelspace into paperspace.

I am definitely an amateur. I do a lot of copy/paste. I recognize terms like pspace, mspace, viewport but i don’t have a solid understanding of them. No i don’t know hoe to exit or resize a viewport.

open your file (the attached one),

click to Layout tab [HP9800], click the [MODEL] button in your statusbar below

SAVE the file

open YOUTUBE

search for

AutoCAD Model and Layout

In short:

In model tab is your model

Layouts are like papers, you can add Viewports to the layout, it's like cutting a hole to see the model content

So, you saw/see in Model tab and in Layout tab the same objects, the objects from the model tab 🙂

No worries, you said in the first post that everything disappears when you convert it to PSPACE

What command or method are you using to 'convert' the objects?

got it: consider helping yourself to online tutorials as noted by others, this is not a program you just dive into, start messing with model/paper space and hope it all works out in the end.

To exit a viewport, move your cursor away from it then double-click. Or type PSPACE then hit <enter>. There is no need to resize it, whomever created it did it correctly and it is ready to use as is. If you are trying to change scale of the viewport (and thereby also messing with the modelspace titleblock size) you can read about how to do that here from HELP inside your program https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2020/ENU/AutoCAD-Core/files/GUID-9929178F-64E4-4B76-BDE2-00BFDAEFC8B6-htm.html

Thanks to all who replied. I'll definitely watch the videos to develop a better understanding of viewports.
