Compatibility Issues between Versions

[Anonymous]

I have seen problems at my work between using newer versions of CAD and older versions - lines not parallel at 0 degrees, hatching all over the place, waiting 5 minutes for files to open. However, we have upgraded to AutoCAD LT 2020 and AutoCAD 2019. It seems as though LT does not have the capability to zoom in far enough as the full version of CAD to verify lines are not lining up or snapped to the correct points. Has anyone else ever noticed issues like this when you have to work between different versions?

No,

If you talk about the same file.

I have to answer NO as well, never any problems. Post a .dwg file showing this behaviour so we can see for our selves.

When you reach the limit do a regen and you will be able to zoom in further.

It seems like you've got more severe issues and I don't think they are programmatic.

I have been saying I think it's our computer's own compatibility with my company. But I wanted to be sure other people were not experiencing the same problems.

Thanks!

I think you are wrong. The things you are describing are not usually caused by hardware issues. They can be exacerbated by lower end hardware but the root of the issue is usually in the drawings themselves.

>>>...lines are not lining up or snapped to the correct point...<<<
You are noting bad drafting in the source file, not much else. Can to prove it? Post a DWG file, we all have old and new versions of AutoCAD/LT to see it all for ourselves.

>>>...waiting 5 minutes for files to open...<<<
If you used migration tools you probably dragged along an old problem into newer versions: a reset of the program plus ensuring you all have the 2020.1.3 and 2019.1.2 updates installed in those two older versions is the first thing you ought to correct. ABOUT command in each program will confirm if you have these updates or not.

>>>...LT does not have the capability to zoom in far enough...<<<
Do you just need to trigger REGENALL command to refresh your display/let your video card catch up? It happens, even in full AutoCAD. Perhaps those users at your office have better PCs/video cards?

That shouldn't be the case, but perhaps you have different settings for SelectionOffScreen

>>"to verify lines are not lining up or snapped to the correct points. Has anyone else ever noticed issues like this when you have to work between different versions?"

Perhaps, in rare situations with a bad environment/data base, it is possible - but i think no(really rare and very special).

Let's talk about your data: Is it really far away from 0,0,0 WCS?

Set UCS to WCS and use command: ID (and click in the upper right corner of your used modelspace.

?

That should not the problem so long we talk about the same file, but i ask as additional information:

What filetype are you using, DXF or DWG

I have attached a file that shows an example of what happens all the time between us engineers and our versions. I wonder if there was something stuck in the original template we use for jobs that could possibly be messing something up.

[Anonymous]

It is first opening as a .dwt from our company's template, then a .dwg once we save it as a job file.

There doesn't appear to be any problems in your example. Of course, what you say in the text is that things aren't aligned but not which things.

[steven-g]

Your drawing opens almost instantly, I see your note about 'this is a perfect example' but of what the drawing looks fine. I can zoom out until the drawing vanishes, or into a grain of sand.

The DEFPOINTS bubbled area in the drawing is meant to show how things get adjusted with lining up when we open between multiple versions of CAD - full and LT.

Thanks for sharing the file.

What am I supposed to be looking for here as a problem?
