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.
I want to assert force at angle of 10 deg to 90 deg at increment of 10 deg. I am standing at centre of room and have walls on both sides. starting from left which is 0 deg to straight which is 90 deg I want to check the feasibility and calculate deformation. Walls are upright and parallel only I move at 10 deg.
How can I work out forces in FEA ? FEA has option either perpendicular (Normal to face) or vector in X, Y or Z only. Is there a way to work out vector force at angle ? I have velocity and distances just need angular forces. See pdf attached for clarity.
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.
Coming from AutoCAD I could create a table in a drawing and input numbers into it. If the number was anything greater than 999 then AutoCAD would automatically add the necessary comma at the thousands or millions place. I have searched high and low in all of the help forums and cannot figure out how to force this behavior in table in BricsCad
I had a deeper look and found this but there must be though a over riding top level setting. It will be part of the table dictionary, I just looked at a table. It is feasible to update all the cells via a lisp.
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.
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.
I am running an autocad script against a library of 40,000 DWG files. All the script does is open each drawing and verify that the correct drawing number is on the drawing. This is for quality control checking.
My problem is some of the drawings have minor inconsequential errors that I wish to ignore. These errors cause dialog boxes to appear which halt the execution of the script and require a manual intervention. With 40,000 drawings this is getting old fast. I have attached examples of the types of inconsequential errors that are being encountered.

Thorlabs' Atomic Force Microscope Educational Kit uses a 635 nm, 2.5 mW Class 3R laser, which necessitates that all users be trained and follow all necessary safety protocols. This includes wearing laser safety glasses.
We would recommend discussing your needs with your organization's laser safety officer. More details about the laser classification system and Thorlabs laser safety products can be found on the Laser Safety tab.
Thorlabs demonstration/educational atomic force microscope (AFM) kit is designed for classroom, lab, and other educational uses. It features an AFM probe, a sample holder on a motorized stage with motorized closed-loop positioning control, a laser and four-segment photodiode detector for measuring the probe deflection, and the intuitive EDU-AFM software package to control the setup.
Operation
AFM measurements use a probe, comprised of a flexible cantilever that supports a nanometer-scale tip, to scan the surface structure of samples. The schematic to the right illustrates how the EDU-AFM1(/M) Educational AFM operates. Laser light is provided by a 635 nm fiber-coupled benchtop source. A patch cable feeds the laser light into a collimator consisting of a lens in an adjustable zoom housing. This collimator is mounted on a 3-axis kinematic mount so that the focused laser spot can be centered on the cantilever surface. Light reflected from the cantilever enters the detector mount assembly, where it is again focused onto the surface of a four-segment photodiode. The voltage measurement from the photodiode provides a measurement of the cantilever deflection that can either be used directly to create an image or in a feedback loop to control the height of the sample stage.
Sample Stage and Cantilever
In the EDU-AFM1(/M), the probe remains stationary while a sample is moved underneath the probe tip using a MAX311D(/M) 3-Axis Stage with Closed-Loop Piezos. The probe is held in a custom mount secured to an AMA009(/M) Platform that connects to the stationary side of the MAX311D(/M), as shown in the image below. KPZ101 K-Cube Piezo Controllers are used to drive each axis of the sample stage. The piezo controllers for the X and Y axes are each paired with a KSG101 Strain Gauge Reader, which measures the piezo deflection. Together, these K-cubes provide closed-loop control to accurately set and maintain the stage position in X and Y. The KPZ101 used for Z-axis control is connected to a KPA101 K-Cube Position Sensing Detector Auto Aligner with an internal digital signal processor (DSP) that is used to monitor the cantilever deflection, as explained below.
