26.03.2022 The PlotCalc server has been moved from Dnipro to the data center in Kiev just in case. Also, the server has improved query processing, now queries are processed in parallel instead of one by one, which makes it comfortable to work during peak loads

04.03.2022 Added Kazakh language pack

02.03.2022 Corrections for CorelDRAW have been made

14.02.2022 Starting with PlotCalc 2022.02.14, the ability to compactly place grouped objects on a sheet has been added; now PlotCalc sees such objects as shapes instead of rectangles. This feature comes in handy for preparing a layout for multi-layer processing, such as a cutting layer, a milling layer, a printing layer, etc.

If the group contains curved lines together with a bitmap, then the bitmap is ignored - this is done for convenience in preparing the layout for contour cutting. Otherwise bitmaps are treated as rectangles.

Also, when using the function to speed up film sampling, auxiliary lines are now grouped together with the original object, which is convenient for their further placement on the sheet.

Plus, the "Circulation" function has been added, which allows you to place multiple copies of an object on the sheet.

- Fixed a bug of number overflow when calculating complex curves with a large number of subpaths, e.g. long texts as curves;
- Removed UI blocking on capacious counting tasks;
- Added language packs: Ukrainian, English, Chinese, Polish, German, French. With the help of the service DeepL

12.01.2022 PlotCalc automatic installer for Windows 11, 10, 8, 7, XP (64/32 bit) is now available

07.01.2022 A beta version has been released PlotCalc 2022.01.03 for CorelDRAW 2021, 2020, 2019, 2018, 2017, X8, X7 (64/32 bit)

16.11.2021 Effective 17.11.2021, the price for a 1-month activation code will increase from $3.99 to $4.99

31.08.2021 Since withdrawal of funds from WalletOne payment acceptance system in Ukraine became unexpectedly impossible from 1.09.2021 acceptance of payments for purchase of activation codes through WalletOne system is temporarily stopped for an indefinite period of time. WalletOne support service informs that the terms of restoration of regular work of the service are not set. Now any attempts to withdraw funds end with an exception. Attempting to make refunds to all customers through WalletOne from 01.08.2021 to 31.08.2021 without canceling activation codes also results in an exception.

At the moment the acceptance of payments through Visa and MasterCard is working properly, also for organizations from Ukraine you can pay on the r/s. Addition of alternative systems (Bitcoin, PayPal, WesternUnion, etc.) will be considered later.

12.08.2021 Unfortunately on 12.08.2021 and 13.08.2021 from 9-00 to 17-00 PlotCalc server will not work due to repair work and power outage. Attempt to solve the problem with the help of SB and AKB did not lead to a positive result.

25.11.2018 Improved the delivery of activation codes to the user after payment.

15.09.2017 To increase the stable operation time of the PlotCalc server in the event of a power outage, a long-life uninterruptible power supply with a 40 amp-hour battery is installed.

10.12.2016 Unfortunately PlotCalc server will work unstably until 01.01.2017, with interruptions, it is connected with Windows licensing.
I do everything possible to normalize the server in the near future!

09.11.2016 The price for unlimited activation code will be increased from 99$ to 149$ c 01.12.2016, if you were going to buy such a code, I recommend to make it before the specified date.

20.10.2016 Some optimization of the server has been performed, bottlenecks have been removed, stability and speed have been improved. Further optimization of the server part is in progress.

02.06.2016 Unfortunately, cooperation with ROBOKASSA payment service is discontinued, but WalletOne service is connected, which has 130 different payment methods. Added My Check section where you can find the payment information as well as the purchased activation code (the section appears after payment in the upper right part of the page).

07.04.2016 Due to a strong reduction in the number of sales, the price for the activation code for 1 month of operation has been reduced and is now - 3.99$

23.12.2015 Happy New Year 2016 to all!!!

08.09.2015 As of today, you no longer have to wait 15 minutes for the first code activation, so you can activate and use PlotCalc immediately after purchasing the code, but repeated activations still require a 15 minute wait.

01.08.2015 Now every Saturday and Sunday PlotCalc will run completely free without requiring activation.

23.06.2015 Due to an increase in the price of the activation code for 1 month of PlotCalc, the price has been changed and is now $4.99$

09.06.2015 PlotCalc server auto-restart function is implemented, in case of server hang-up the server will be restarted in 5-10 seconds automatically, you won't even notice anything. And if the server hangs while performing your operation, you just need to repeat the operation again.

22.05.2015 The equipment has been replaced and the provider on the server side has been changed to improve the quality of the service. New server ip-address

02.04.2015 PlotCalc version for CorelDRAW X7 32-bit is now available.

15.02.2015 Added the ability to purchase codes through ROBOKASSA system (more than 40 payment methods).Also added the ability to purchase an activation code for one year of work for 29$.

23.01.2015 Due to changes in the legislation of the Russian Federation today ceased cooperation with the store AllSoft, activation codes purchased in the store AllSoft after 23.01.2015 are considered invalid, if you bought codes in the store AllSoft after this date, in this case, make a refund. Additional payment methods for codes will be available soon.

02.10.2014 It is now possible to purchase an activation code for one month of work for only 2.99$. The payment system has been improved, now activation codes are sent instantly after payment, and for customers from Ukraine there is an opportunity to buy codes in cash through a PrivatBank terminal or using liqpay account. In store there are for sale activation codes for an unlimited period of time, as well as codes for the 1st month of operation.

Activation codes have changed their look a bit for better readability, now all new codes look like this:
AAxxx-AAxx-AAxx-AAxx - code for two years;
MONTH-AAxx-AAxx-AAxx - 1-month code;
UNLIM-AAxx-AAxx-AAxx - code for an unlimited period of time.

Attention! Activation codes for 1 month or unlimited time cannot be used for PlotCalc 5.0.1 and below. For PlotCalc 5.0.1 and below, only 2-year codes can be used. I remind you that the activation system for the new and old version works independently (in parallel), you can check the codes here: Activation

14.10.2013 Prices for activation codes have been changed, now one activation code has a price of 49$, two codes - 69$. Added activation code valid without time limit (price: 99$)

25.07.2013 ATTENTION! Server IP address has changed:

02.04.2013 Restored normal operation of the server, previously the computer on which the server was installed failed, the server was moved to another computer at that there were problems with activation, now it is fixed.

04.10.2012 ATTENTION! The IP address of the server has changed:

24.08.2012 Changes have been made to the PlotCalc server part:
- added sending of information about the progress of primary processing;
- eliminated temporary server freeze at simultaneous request from a large number of clients;
- server RAM overflow was eliminated.

19.08.2012 It is possible to pay directly with cards with VISA or MasterCard logo.

14.06.2012 There is now a version of PlotCalc compatible with CorelDRAW X6.

5.06.2012 PlotCalc 7.0.0 is now available, and the following changes have been made to this version:
- The nesting algorithm has been completely rewritten and many new features have been added;
- bug with curve length calculation has been fixed;
- bug when using the "film cleaning" function has been fixed;
- the activation procedure has been simplified.
WARNING! PlotCalc version 6.x.x is no longer supported!

25.05.2012 PlotCalc version 7 will be released soon. The following changes in the nesting algorithm will appear:
1. Possibility to fix the angle of rotation of the figures, e.g. 0, or 180, or 90.
2. In case the material size exceeds the size of the working area of the machine, PlotCalc will be able to place shapes on the material while indicating the lines along which the material should be cut.
3. Possibility of placing elements inside any figure.
4. This function can reduce material consumption by about 5%-10%, but it takes time, i.e. you have to compromise between savings and time.
5. Activation conditions have been improved for the user, activation has become easier and now the number of activations is not limited, while the activation code usage period and price are preserved (2 years from the first activation, 29$ US), but the system is made so that you can use PlotCalc only on the computer where the activation was made last, and between activation attempts cannot be less than 15 min., i.e. if you try to use one activation code on 2 or more PCs at the same time, the system will make it as inconvenient as possible and you will have to buy a new activation code. Also the new activation system will work in parallel with the old one, i.e. the activation code used earlier in the old version (PlotCalc 3.x-5.x) will become working again, so if you have used codes - save them and they will work again in the new version, this is done to save old customers.

20.03.2011 PlotCalc 6.0.5 beta:

23.10.2008 Due to the instability of the U.S. dollar, the price of PlotCalc software (add-in-CorelDraw) in the national currency of Ukraine, as well as in rubles of the Russian Federation, now the price is displayed in hryvnias and simultaneously in rubles of the Russian Federation.

7.05.2007 The 5th version of PlotCalc has been released, in the new version the main changes were related to the modernization of the optimization algorithm for shape maps.

The following has been implemented in PlotCalc 5:
- Multiple Placement - you can now place grouped objects;
- It is now possible to place objects that are not curves, such as text blocks, shapes, unclosed curves, and even bitmaps. Now PlotCalc does not "tell" you to convert graphical objects to curves beforehand;
- The interface for the shape map optimization function has been changed;
- Changed the interface for PlotCalc activation, now there is no need to send a cipher to the support address during activation (activation will take a couple of minutes);
- Increased by several times the performance when placing figures containing too many nodes (for non-optimized or inaccurately created figures).

To upgrade to a new version (PlotCalc 5), no reactivation is required, just uninstall the previous version and install the new one.

21.04.2007 Activation code verification via web-interface has been implemented; Now by going to the Activation section you will be able to check the detailed information about your code.

19.04.2007 It is now possible to activate PlotCalc in "manual mode" without sending the cipher to the technical support e-mail. Now to get the key file, it is enough to generate a cipher and go to this page.
