1.The biggest trouble is causing probably AutoCad error, what doesn't allow use "solprof" command more than three times, when running in AutoLisp mode. Using fourth time "solprof" command causes "AutoCad" crash with error report: "FATAL ERROR:"commands may not be nested more than 4 deep". To reload "AutoCAD"and answer to all "AutoCAD" questions every time is very boring. So in SteelAce have built-in counter, what doesn't allow with SteelAce do more than three "solprof" projections. When you try to do more projections, then in most of cases you receive message "Projection limit exeeded", in worser cases you receive "Abnormal command termination". When you did't get message "Abnormal command termination", but you know that three projections are already done, then before next using of SteelAce's commands do File->Reopen and View->Refresh. You can see these commands in Pop menus, when you edited menu as described in Installation. If you want see how AutoCAD crashes then load "crash.lsp" enter "crash" command on command line and pick one solid. Download
2. When executing "SteelAces" commands AutoCad cannot suppress all echoes even if variable "cmdecho" is set to 0, also on screen cannot be suppressed showing command executions when AutoLisp runs them. It should be look out much better of course, when user can see only result of command, but not all confusing activity on screen.
3. When using cylinder command it may be problem to select cylinder so, that SteelAce can find outer boundary of it. SteelAce normally tries to correct selected entities itself so, that it is possible to find boundary. But sometimes that correcting is not succesful and it causes "Abnormal command termination". If you are sure, that your outer boundary is correct then SteelAce's correcting is probably not needed and you can turn it off switcing on command line: "setvar"-> useri5-> 5. Of course you must set that variable back to any other value (for example 0), if you want afterward use SteelAces correcting again. That critical place is in Dynamic.lsp and if you know lisp language you can edit it itself. You can find that critical place searching the word "critical". That boring moment will be surely made better in future.
4. When you see after executing command on history screen ("AutoCad text window") message "Abnormal command termination", then it can cause crashing SteelAces database, even if at first all seems working well. For example SteelAce don't check on regeneration of block if the defining contours are closed, not exploded or even erased, SteelAce just crashes. Also SteelAce crashes, when you define block solids the way, when at least one solid is absolutely deleted with "subtract" command by another solid.The last case happens rarely of course. Remember, that spaces are also solids, just defined another way.
5. When you think all conditions mentioned above are right, but you cannot regenerate "SteelAce"-s block. (You see message "Abnormal command termination"), then exit "AutoCAD", start it again and try again, it may be also just AutoCad error.
6.In "bill of materials" position deleting and restoring is very good thing, except "Delete" key deletes not only row, but also char in this row. When restoring that row with "Insert" you can restore that deleted char or use "Delete" key in such place, where it cannot delete char. If you want to delete chars on row use "Backspace" instead of "Delete" key.
7.For crosslines is possible to use only 90 degrees zigzag polylines or just one line. Usually you can see only full cylinders on crosscuts, so crosslines are recommended to create with considering that condition. Fortunately making crosscuts is easy, so you can create just more crosscuts.
8.When building "SteelAce"-s block you can add main plates only above upper plate and below lower plate, in middle plates you can place only "Insert" plates. You can delete main plate only when all "Inserted" plates and drafts are deleted on that main plate level. If you don't want see main plate, then switch it off with toggle. You can move within level with ">" and "<" buttons.
In future releases of "SteelAce" these drawbacks will be eliminated as much as possible.
