Any DWG DXF Converter is batch DWG and DXF bi-directional converter and file version converter, it allows you to convert DWG to DXF, DXF to DWG without the need of AutoCAD. (New - 2008 support).
Key Features
- Stand-alone utility - AutoCAD NOT required.
- Convert DWG to DXF, and DXF to DWG in batches. It is also a DWG/DXF file version converter.
- Supports every version of DWG/DXF files (R2.5 to R2008 DWG/DXF formats).
- Very easy to use.
- The "Pro" version supports command line.
Понятно. Пакетный конвертер из DWG в DXF. |

Есть такой прот для lisp-програм в среде Bricscad [странно, но другие IntelliCAD-САПРы его не афишируют] - BcadLispEcrypt [http://www.sabit.com.ua/applications/]. Файлы программ шифруются, их можно определить по строке 'BricsCAD ENCRYPTED LISP file'. Собственно сабж с этим борется и выдает исходный листинг [русский язык не поддерживается, но это косяк прота]. Принимаются заявки на дешифровку других систем защиты [AUTOCAD PROTECTED, DES PROTECTED LISP, AUTOCAD LT OEM, etc.]. Мне оно не нужно, а реализуется довольно просто. |

Bentley Systems официально опубликовала релиз
2007 программы по расчету конструкций
STAAD Pro.
|
 |
|
Bentley’s Research Engineers Solutions Center has released STAAD.Pro 2007 – Bentley’s comprehensive structural analysis program for static, dynamic, or pushover analysis of bridges, containment structures, embedded structures (tunnels and culverts), pipe racks, steel, concrete, aluminum or timber buildings, transmission towers, stadiums, and other structures.
The STAAD.Pro 2007 interoperable design software supports more than 70 international design codes. It addresses recent changes in European, U.S., and Southeast Asian design codes, and is well suited for a variety of vertical applications, including plant, civil, and building.
STAAD.Pro 2007’s key features and enhancements include: |
|
Integration of RAM Connection – Users of STAAD.Pro 2007 can analyze, design, and produce 2D drawings of simple and complex connections within the STAAD.Pro environment. Shear tabs, moments connections, splices, and bracing connections (gusset plates, chevron, and knee) can be modeled, optimized, and grouped (as well as individually customized), taking into consideration all applicable load cases.
Integration of AutoPIPE – Pipe stress engineers can integrate their piping model with the structural model and vice versa. This eliminates the need to manually transfer loads and support positions on isometric drawings and shortens the time to produce final contract drawings and purchase steel. The combined model will be more accurate since it takes into consideration a combined stiffness. |

The application of OLGA® (ex OLGA2000) as the transient modelling tool is particularly valuable in:
The Planning Phase:
Analysis and design of crucial characteristics
* Slugging and surge (tube ID, well profile)
* Gas lifting
* Clean-out and testing (equipment sizing / clean-up economics)
* Cross-flow
* Liquid loading onset prediction
* Thermal calculations, hydrate and wax
* Water accumulation, corrosion and material selection
* Checking lift curves for both steady and unstable flow
The Operations Phase:
Forecasting flow problems and instabilities, trouble shooting and
selecting appropriate remedial actions
* Liquid loading predictions, water cut limits and remedy evaluation
* Operational trouble shooting
* Operational procedures (Start-up – Shut-down)
* Predicting Bottom Hole Pressure from surface measurements
* Well testing
* Virtual multiphase downhole flow meter
* Artificial Lift Optimization (Gas Lift (intermittent), ESP, Plunger Lift, etc.)
OLGA® accurately models and analyses true dynamics, and is the market leading simulator for all
flow of oil, water and gas in wells, pipelines and receiving facilities.
Understanding the impact of complex flow regimes in wells is important for production optimisation.
Well flow performance is typically designed for maximum production rates using steady state simulation tools. This gives limited knowledge of the behaviour and control of the wells inherent
dynamic conditions. |
