What are the BricsCAD minimum system and hardware requirements?
Processor
1 GHz processor or faster, or compatible processor.
Memory
Next to the memory required by the operating system, BricsCAD requires 256 MB (1 Gb or more recommended).
Hard Drive
250 MB for program files + 1 GB free space.
Display
1024 x 768 XGA with true color (minimum)
Supported GPU (**): see below for more information on supported chipsets for GPU acceleration for non-wireframe render modes such as realistic rendering. Please note that non-wireframe render modes and all other features of BricsCAD can still be used without hardware acceleration.
More information
(*) Supported Linux distribution versions:
Bricsys has chosen to support Ubuntu, openSUSE and Fedora.
BricsCAD (Linux) V16,V17 is built with gcc 4.8.2 on Ubuntu 14.04 LTS. As a result the minimum required c++ runtime (libstdc++) is 4.8.2. In practice, BricsCAD (Linux) can run on almost any distribution that is newer than Ubuntu 14.04.
We receive many support requests for other distributions. As a rule of thumb, if we can reproduce the reported issue in one of the supported distributions, we provide support for it.
(**) BricsCAD's non-wireframe render modes are based on RedSDK technology from Redway3D®.
GPU-acceleration for these render modes requires a supported GPU (graphic processing unit), either on a video card or on the motherboard.
On Windows, all graphic cards from NVIDIA, ATI and INTEL are supported by RedSDK
On Linux, 3D graphics hardware acceleration in RedSDK is supported on the following video chipsets:
NVIDIA cards. It is advised to use the latest recommended driver from NVIDIA.
ATI cards. It is advised to use the latest recommended driver from ATI/AMD.
3D graphics hardware acceleration in RedSDK on Linux is NOT supported on:
INTEL cards. As opposed to ATI and NVIDIA, 3D hardware acceleration in linux drivers for INTEL cards is relatively new. So far we do not yet officially support 3D hardware acceleration on INTEL cards, although we are working on it.
Laptops with dual graphics, although it happens to work on some dual graphics systems using recent versions of proprietary NVIDIA drivers.
What is a network License file?
A nework license file is a text file that contains the floating license keys and is placed on a read/write network location, e.g. in the Bricsys office in Gent there is such a file on:
\\autoinstaller\public\NetworkLicense.lic
Users who want to use the license pool, enter the path to this file in the "Enter License Key" dialog. A radio button was added to choose between a regular license key or a network license file.
The file contains as many license keys as the requested number of floating licenses, e.g. for 5 licenses it could be this file :
KZV6-Z6MB-MQ3N-XYUV-EFWA-DNHG $
9YKR-YKA2-DBPR-GDVS-MWZG-66HE $
D6H3-K2KX-5XBV-MA7G-9YG8-ZTWV $
WV6W-DKB6-ZDX3-UZYA-9G3M-ZVWN $
16YG-WVYJ-BZK7-WK6N-VZ3W-1DAV $
The dollar sign after a key means that the key is not in use. When a BricsCAD session is started, it looks for a license key in the file that follows these 3 conditions:
The user type is "Network License"
The license key matches the product, language, platform, version, etc., just like a regular license key.
One of the following is true:
After the key there is a space + a dollar sign
After the key there is a space + the mac address of the machine this BricsCAD session is running on.
If it finds such a key, BricsCAD starts. If the key was free (dollar sign), then it writes the mac address instead of the dollar sign to lock it.
When BricsCAD shuts down, it replaces the mac address again by the dollar sign.
Note: Do not use the keys from the example : these are not valid license keys.
Symptoms
BricscCAD installs LicenseManager.dll, which supports floating network licensing.
Cause
How does it work?
More information
If BricsCAD crashes or is closed without access to the network, then the license key remains locked, until BricsCAD is closed again that same machine, with access to the network.
IMPORTANT :
It is not possible to lock a key and migrate it to a machine to run BricsCAD when not connected to the network. (e.g. it is not possible to use it on a laptop when this laptop is not connected to the network)
The user on the client machine where BricsCAD is running, has to have write access to the shared network drive where the network license file is placed.
A license key with user type 'Network License', does only work when used in a network license file. It can not be entered as a regular license key. Vice versa, a regular license key (User type 'Single User' or 'Volume License') can not be used in a network license file.
