RCAD Installation
RTOPO Hydrology CAD for topography is an application that runs on our CAD system, called RCAD, with which it is delivered together. The trial version that you can download below also contains another application for RCAD, called 3D CNC milling from DXF + VDAFS to DXF. Below you can see how to install RCAD and how you can download the trial version with the 2 applications.
Requirements:
– Windows 98, XP, Vista, 7, 8, 10 or 11 (32 or 64 bits),
– computer administrator account.
Create “C:\rcad” directory.
Unzip “rcad.zip” in this directory.
On Windows 98 and XP:
“Right mouse on desktop”, “Properties”, “Appearance” (“Advanced” on XP), “Item”->”Active Window Border”, “Size”->1, “Apply”, “Item”->”Inactive Window Border”, “Size”->1, “Apply”, “OK”.
On Windows Vista:
Change “Border Padding”, “Active Window Border” and “Inactive Window Border”: “right mouse on desktop”, “Personalize”, “Window Color and Appearance”, “Advanced”, “Item”->”Border Padding”, “Size”->0, “Item”->”Active Window Border”, “Size”->1″, “Item”->”Inactive Window Border”, “Size”->1, “OK”.
On Windows 7:
Change “Border Padding”, “Active Window Border” and “Inactive Window Border”: “right mouse on desktop”, “Personalize”, “Window Color”, “Item”->”Border Padding”, “Size”->0, “Apply”, “Item”->”Active Window Border”, “Size”->1, “Apply”, “Item”->”Inactive Window Border”, “Size”->1, “Apply”, “OK”.
On Windows 8:
1) run the program as an administrator: right mouse on “c:\rcad\rcad.exe”, “Compatibility”, “Run this program as an administrator”,
2) set “BorderWidth” and “PaddedBorderWidth” to 0, using Registry Editor (Regedit command): “Run” command (move your mouse to the upper right corner until the “Charms Bar” pops out., select “Apps” from the list and type “run” in the search box; click on “Run” from the search results), in Regedit select HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics, set BorderWidth 0 (by double-clicking) and PaddedBorderWidth 0, restart the computer; If you have trouble moving the RCAD toolbars, set values between -15 and -60 instead of 0 (values must be negative).
On Windows 10/11:
1) run the program as an administrator: right mouse on “c:\rcad\rcad.exe”, “Properties”, “Advanced”, “Run as administrator”,
2) set “BorderWidth” and “PaddedBorderWidth” to 0, using Registry Editor (Regedit command): in Search (in the lower-left of the desktop, next to the Start button), type Regedit, and then select Registry Editor; in Regedit select HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics, set BorderWidth 0 (by double-clicking) and PaddedBorderWidth 0, restart the computer; If you have trouble moving the RCAD toolbars, set values between -15 and -60 instead of 0 (values must be negative);
If everything appears too small on high resolution displays, press the right mouse button on C:\rcad\RCAD.EXE, Compatibility and uncheck “Disable display scaling on high DPI setings”.
3) to see the Help: in File Explorer, right click on the “C:\rcad\rcad.chm” file, Properties, check Unblock (in the Attributes section).
——————–Settings problems——————
If the graphics card has not OpenGL or the OpenGL drivers are not installed, the image may be upside down or can remain traces on the screen, when you move the mouse.
Similar effects can occur if the color depth is not 32-bit.
If you don’t set the Window Border and Border Padding to 1 and 0, the toolbars appear incomplete or distorted.
If you don’t run the program from a Windows administrator account or as an administrator (Windows 8), the program exits with an error message (privilege violation or the trial version is expired).
If you can not see the Help, find the solution, by searching in Google “can not see chm files in Windows”.
