I spent a couple hours modifying an existing AutoCAD LT for Mac dwg but had to Force Quit when a hatch command caused the program to freeze. When I went to find the backup or saved dwg file, the only one listed is from 6 days ago. Why doesn't AutoSave do what its name implies?? Two hours of tedious work down the drain.
The first thing we should check is where you are looking for the recovery DWG file. Fusion recovery files can be found in the locations at this link. If you are looking for a recovery DWG file in Windows File Explorer or Mac Finder, you will not find it - you will only see the original DWG file. After a DWG file is uploaded to the Data Panel in Fusion 360, it is translated to F3D (Fusion native) format. You will not find a recovery DWG file - this is because Fusion 360 does not keep the file in DWG format.
There are some safeguards in place. When an auto-save is canceled due to option 1 & 2 above, it will continue to attempt to auto-save on a 1 minute interval once the user finishes the current command. If too many failures happen in a row, a forced auto-save will happen as soon as the operation is finished. However, this does requires a state of quiescence to successfully complete the save.
I should have mentioned that I disabled iCloud due to it causing many issues with the Mac AutoCAD Lt software. So now I'm assuming that by doing this I also disabled the AutoSave function? I don't use Fusion360, as it requires access to the cloud. Am I correct in saying this?
Thanks for the response - I notice now that you mentioned this in the initial post, but I did not notice you are working with AutoCAD LT. I am not an AutoCAD expert and will transfer this post over to their forum board. Some of our experts over there should be able to help out.
I am sorry the AutoSAVE did not save your file in this instance. I do not recommend setting it more frequently than the default as this can actually cause more problems by too frequently accessing your hard drive. In my opinion, there is no substitute for a manual Save. An autosave is intended to provide an opportunity to recover data in case of a crash. It might not always work though depending on the status of the crash, when the last autosave was performed, if it has inadvertently been turned off, etc.
When Fusion hangs and lags for what seems to be an indefinite period of time, and you find yourself staring at the unfeeling spinning wheel of death and knowing there is no way to take back control other than a force quit. Instead of potentially wrecking your hard work for the gamble it was saved, what about a "force quit process" using the "Command . (period) keys"? to stop the last command and regain control?
I am afraid the problem is deeper. I think F360 is missing a proper crash handler somehow, and once there is an unhandled exception or other stack overflow or whatever happened, there is no programmatic way to regain control.
I am saying this is OS controlled, the only way for Fusion not to do it is for it to get fixed. Somewhere there are missing try catches, or who knows what. So I'd report them as bugs. The only way I can think of to implement what the OP is suggestion would be a separate fusion process monitoring the main, but at best you probably won't get your files back.
My original thought was if, say in Sketch, I try to use a pattern or mirror tool command and then F360 just hangs and hangs as it tries to process, It would be cool if there was a key command to cancel that process so we could try a less intensive solution. Is that the same as needing another layer to monitor F360 as you described? I can see how that would be an overall OS issue.
We are currently working on this with the ESC key so that you can kill process that is taking too long or crashing. Right now, we're working on making it work for Compute All, fillets, and some other modeling related solves. We still need to investigate the work for sketch solves since Fusion has different solvers for different workspaces/environments. We'll keep you posted on our progress.
With infinite computing power still not in view, I would like to request this to an elevated priority. I lose way more time than I'd like to admit to unfortunate line movements with crazy math attached, to the point of considering different software.
Any progress on this issue in versions 2010-2013? I came across this situation today trying to create an exhibit (at a different scale) from a plan/profile drawing, where the scale of the C3D lableling looks fine in plan view, but is too large (by a factor of two) for the exhibit. I remember similar display problems in the past, anything new in the latest versions I should be aware of?
I do this by creating an Expression for fixed heights and using that for the text height in the Style. You have to create one style for each height. These are usually used for stakeout diagrams where we want to show the points quite large but not have other text and notes scaled up.
This is the expression for a height of 0.6 of the drawing scale 0.6 / Drawing Scale Conversion. It's from a metric drawing. You can paste that in to the Expression or you can get the Drawing Scale Conversion by clicking on the function icon in the Edit Expression dialog box.

As Allen says, you can always create a Style that forces a specific height. But that gets back into the "Style Breeding" problem, as well as creating tons of Styles that confuse junior users (or anyone new to your company), so I'm not particularly a fan of that process.
There's a weakness in C3D where, especially if you are using the Plan&Production tools, it is NOT easy to create plots at different scales. I was dealing with this issue recently in some of my training, where they wanted to be able to create plots at 24x36 as well as at 11x17, yet they didn't want to simply scale down the bigger drawings to 11x17. My recommendation was to just create everything at 24x36, then use a Page Setup Override (via the Sheet Set Manager) to print an 11x17 version, even though that would result in things like your Scales being wrong. After all, in practice, it's a bad idea to scale things off an 11x17 reduction in any case, so why worry that the scale isn't right...?
But then, we've also been moving toward giving plans to our field guys in the form of a tablet (like an iPad), so they don't even have paper plans at all anymore... That kind of really throws away any desire to scale off a reduced set of plans.
It really pains me to say this, but I have been known to enlarge my title block, calculate out alternate viewport scales, then "scale to fit" my drawing. (Say for instance, scaling a title block up by 2.5x to get 20 scale annotation on 50 scale viewports, making a 30x42 drawing into a 75x105 drawing) I really hate doing that because it's prone to error when other people work with your files, but it can get you a 50 scale drawing with 20 scale text. You also have to then set the print scale at the inverse (1/2.5 = 0.4) or scale to fit. The scale to fit is tricky--because you have to have a boundary at the edge of your limits and 0 margins, or else you get something dumb like 0.38 instead of 0.40 scaling.
First, import the points into the exhibit and drag them around until they look good at the desired scale. Then use quick select to export only the cogo points to a new drawing. Then xref the new drawing into the exhibit. Finally, turn off or delete the actual cogo points in the exhibit and you're left with the xreffed points that look right. Sounds complicated but it only takes a minute or two and there's no need to create "compensator" styles.
If you create a polyline in AutoCAD and check quickproperties it is indeed a polyline.If you now keep the begin and end vertex and remove all in between and check quick properties, autocad still says it is a polyline. Afaik, you cannot (over)write the autocad parameter to do so. I would argue that to call a line a polyline would be like realizing that you can identify a square as a heavily stroked circle. (even if it brakes some circle rules)
Please create an attribute on the output features named autocad_original_entity_type, and set it to autocad_polyline. This will force the output to be a polyline, regardless of the number of vertices.
Using a text file (.TAB) with the list of commands and layers, you can force AutoCAD to e.g. place all texts to the layer "ANNOTATIONS", place all hatches to the layer "HATCHING" and dimensions to the "DIMS" layers with predefined layer colours. You can also set block names which should be inserted to predefined layers - e.g. all Chair* and Table* blocks to the Furniture layer.
