I have used MathCAD since 1997. Loved it. I used to work for the Nuclear Industry in Canada, and we had these long calculation sheets fully written in MathCAD. As an independent researcher, I also had a student version which I could simply purchase from a campus bookstore as a CD. A few years later, disaster struck! A greedy corporate entity purchased MathCAD and destroyed it. A tool created for engineers by engineers with engineering in mind was destroyed by MBAs with only money in their minds. I was helpless until I discovered SMath. I was amazed at how SMath could do so many things with the installation file being just a few MB! And Andrey simply gave it away to us for free!! SMath has truly filled the void left by the now-extinct "old MathCAD". The fact that SMath is not bloatware and gives us researchers exactly what we need are reasons enough to call Andrey a genius. My dear Andrey, many of us are out there in various parts of the world quietly blessing you for helping us do our research calculations. You are a noble soul with a spirit that cares for a better world. Trust me, you have in your own way made our world a better place to live through SMath. God bless you. I shall surely donate an amount as a symbolic gesture for your great work. Please continue to serve the world and may God bless you with good health, a long life, peace, prosperity, and a sound mind that scientifically contributes for as long as you live and pave the way for your glorious legacy long after we are all gone.

Andrey has given us back the joy of Math that we experimented with Mathcad some thirty years ago, until PTC messed it all up. A fantastic achievement! And free! I am beginning to use it intensively to help my engineering students.

An amazing math tool, a must-have for engineers and scientists everywhere. (And it's not bad as a quick expression evaluator, either.)

by Mike Williams
You should definitely try and use SMath Studio. This “one-man” project is really awesome. I can state, with no doubt, that every Mathcad user will be rather surprised.

I am using it everyday for my professional work. Thank you so much!

by Tien Nguyen
Great tool for all engineers. It's very user-friendly and has lots of functionalities that can be further extended by installing plug-ins (it takes just a few clicks, no need for tedious file manipulations). SMath can operate on units, perform symbolic calculations and many more. Also, it has very clear interface and all formulas can be entered just like you would do on a piece of paper. What's more, the software has great community of people willing to help with various issues.

If you move a region with the mouse, it sometimes vanishes. For the attached sheet this is particularly reproducible. It seems to be limited to moving regions upwards. Downward move never remove a region. Recovery from such deletions is just by Ctrl-Z. Sorry this example requires Maxima. Perhaps it is related to Maxima, but non-Maxima regions are affected as well. HV_WEZ.txt (1kb) downloaded 57 time(s). HV_WEZ_lsquares.sm (103kb) downloaded 61 time(s). The new page view isn't just a page view, it also wraps region and as such changes the formatting of the document. Edited by user 02 February 2018 02:10:01(UTC) \| Reason: Not specified

Yes, I can confirm there are some issues appears because of collapsed areas. It is regarding moving regions and drawing red cursor. I will address these issues asap. Regarding new way of positioning regions with a page view: yes, there is another approach used for regions locations - they always should be fully visible within a page (with some exceptions). But please, note: view used during work with a worksheet always stored as a part of this worksheet. So, if you have created a worksheet without new pages view turned on, then your program will always show it as you expected. Of couse if someone have designed a worksheet as pages, then you will open these worksheets in pages view automatically (doesn't matter what global setting you use for your copy of SMath Studio). That means your document will never be broken because of the worksheet view you (or someone else) are using. But of course program always allow you to switch between view modes - you just need to understand that such a switch may result in different number of pages on print out (again, you can switch it back to restore initial regions layout). The main idea here is that view switching is safe operation and you are able to play with it without any worries to break a document. But it introduces something new, which may be important for some users. Pages view is always good thing because now I have prepared everything (almost) to start implementation of full functional user defined headers and footers. For me this is a starting point to make SMath Studio better in documents visualization and interaction. Best regards.

I was irritated by the coupling of two features, which as well be could have independent settings, 1. Page view with margins and (possibly later) the headers and footers 2. Page wrap of regions If I want to prepare a document for printout, page wrap is great. But I don't necessarily need a top and bottom margin preview then but rather would benefit from seeing more regions at once on screen. I'd check the margins or headers and footers just occasionally before printout or otherwise publishing a sheet. Thus, the rigid coupling between the two doesn't seem natural to me. Of course, a realistic and editable preview of the margins and decorations is much better than the old style print preview in the File menu. Given the attention which document formatting currently receives, I guess that there are more features in the pipeline like some integration of a rich text region with line wrap, section header styles and the like... BTW I don't agree with other user's statement that formatting is the major advancement in the new stable release. To me, it's the use of indices and index vectors in assignments, much like the Mathcad range variables. In fact, there is good reason to revisit legacy sheets and make them more readable using this new feature. As to the formatting: I like the units being upright instead of italic now and flawless scaling or zooming is great. I am not so convinced of the small font subscripts, as they force me to use a larger base font or a higher zoom level to be able to read them with my bad old eyes. This againg goes at the cost of the viewable section of the document on screen. How about a viewing option: small text subscript? Vector indices aren't small anyways and I hope they never will be. Best regards, Martin

I have a problem with newly added feature: "Pages mode of worksheet visualization implemented (in test mode temporary; press Ctrl+Alt+L to activate);". I am from Poland and in our language we have a lot of diacritic symbols which are written by using "right alt (ctrl+alt) + symbol" like for example ą, ę, ć etc. and shortcut ctrl+alt+l is used for ł. Implementation of this feature results in accidental changes of "page mode" during normal writing. It would be great if it could be improved. Best Regards.

I have worked a bit with documents containing area regions. The user experience really suffers from bugs because you can't move regions around even without being in margin preview mode. When you release the mouse, the dragged or cloned regions jump away. If that can't be fixed immediately (which is perfectly ok), I'd recommend to issue a 6598-based stable version, possibly with some bug fixes but without new features, or at least re-classify 6606 as release candidate rather than as a stable version. This would keep the trouble of testing leading/bleeding-edge development features within the group of the nightly-builds users.

This will be of great help. I would like to thank ALL of the developers for their work!! Any inkling, from Mathcad on integrating the Writer Region plugin so we can have some formatting out of the box "shading" the page to see blank areas. MathCAD it is "view --> Regions" (Easier on the eyes/screen, and still prints white) insert/delete lines (helpful with inserting images and deleting too much unused space quickly) be able to change default units (sorry, I live and work in the US. I wish we would just go metric already ) updating the PDF files/help guides for the new features. Forums are great but for some reason, my links/favorites are broken. I thought some of the items might be documented in the help Wiki and it's not equation "wrap" for long equations It appears as if Text Region Utilities plugin is not compatible with this version Unfortunately, I've been on site more than designing lately and need to get back into updating files with new features!!!

But latest versions of SMath Studio allows you to work with no matter what DPI is set on your PC. Result will always be the same. Please compare those regions with blue background you have added before exporting to PDF. Do you see strange spaces with 6179 build? This is exactly because old versions of SMath Studio had bugs related to DPI. So, I would suggest just to fix layout for the documents you have. Starting from now you will never see such issues (I really believe so). Sorry for inconvenience, but DPI related bug was really hard to fix and it was very annoying. Best regards.
