New in MicroStation CONNECT Edition Update 8: Shrinkwrapper Mesh Tool

MicroStation CONNECT Edition Update 8 introduces a new General Access Technology Preview  mesh tool: the Shrinkwrapper

This new tool generates a mesh around an exisitng mesh or solid and shrinwraps it to make it as close as possible to the original element. You can think of it as if you are vacuum packing your elements with a "mesh bag" :)

The result is a light weight mesh version of  the original elements.

You can also use the shrinkwrapper to heal an existing mesh where manually repairing all the mesh issues would be too time consuming.

This tool is currently in Technical Peview stage, so should not be used in production and/or on prodcution/live data.

Bentley Institute Student Ambassadors are future professionals who are passionate about technology and enthusiastic about promoting new trends in the industry among their peers. Their key responsibilities are to act as a link between Bentley Institute and their campus for planning and organizing activities which will keep the students engaged and interested in learning Bentley technology. The Student Ambassador’s contribution adds value to academic courses by facilitating activities that bridge the gap between academic learning and the technical skills needed by industry. 

This month, Bentley Institute would like to recognize our Student Ambassador Ting Li, a fourth-year student of Structural Engineering and Project Management from Dalian Nationalities University, China.

Ting Li, a self-driven student, voluntarily grabbed the opportunity to be an Ambassador for her campus in March 2017. Immediately after donning this role she organized a workshop in April 2017 on MicroStation which was attended by 30 students from her campus. Further on, she also organized more learning workshops on BIM solutions and webinar for ContextCapture which was attended by 15 students. Thanks to such sessions her students of Dalian National University are now well acquainted with Bentley software. We also recognize the fact that continuing series of sessions in her campus is a result of enthusiasm shown by her to learn and pass the knowledge on further to her peers.

She makes sure that training sessions are not only about learning but also fun, creative and interactive. In fact, we also had a winning from Dalian Nationalities University for the  2017 Bentley Institute Student Design Competition in the Reality Modeling - General Category.

Ting Li does not hesitate to mention that she is grateful for the opportunity given to her, as it has greatly helped her becoming a good coordinator and leader. She also does acknowledge that learning Bentley solutions have improved her understanding of the BIM approach and it will be helpful for her as she launches her career.

Customization Blog Series - Screen Menus - Blog 3 of 3

0
0

In the previous blog, we added icons to elements and associated key-ins to them. In this blog, let us create saved views, assign keyboard shortcuts to the screen menus, and learn to use the screen menus.

Creating Saved Views

  1. Resize the view window to 330 x 330 using the View Size tool (Drawing > View > Window > View Size).
  2. Zoom in/out to make sure all elements display properly in the view window.
  3. From the Level display dialog, turn off the Extended level.
    You will observe that the outer circles and their icons disappear.
  4. Start the Create Saved View tool (Drawing > View > Saved Views > Create Saved View).
  5. In the Create Saved View tool settings window, enter the name as Menu-1.
  6. Enter a data point in the view window.
  7. Now turn on the Extended level.
  8. Start the Create Saved View tool again.
  9. Name the new saved view as Menu-2 and enter a data point in the view window.
  10. Now select Associate Key-in and then select the circle to which you assigned the Shortcut Key <+>.
  11. In the Edit Associated Command dialog, select Menu-2 from the Saved View drop-down and click OK.

Tip: In case you make any changes to the screen menu, do remember to update the saved view.

Assigning Keyboard Shortcuts

Now let us assign a keyboard shortcut to the screen menu.

  1. Open the Keyboard Shortcuts dialog (File > Settings > User > Keyboard Shortcuts).
  2. Click Add.
    A new blank entry is added to the list.
  3. In the Key list box, enter the character </>
  4. In the Label field, enter “DraftingScreenMenu” 
  5. In the Key-in field, enter SCREENMENU OPENPOPUP SampleSM.dgnlib,Menu-1,Menu-1.
    The syntax is:
    SCREENMENU OPENPOPUP <dgnlib_filename>,<model_name>,<saved_view_name>
  6. Click Apply and save the file.

communities.bentley.com/.../7144.Video_2D00_4_2D00_1.mp4

The above syntax in the keyboard shortcut will open the screen menu as a pop-up.

Let us add another keyboard shortcut, but with a different syntax:

  1. In the Keyboard Shortcuts dialog, click Add.
    A new blank entry is added to the list.
  2. In the Key list box, enter the character <]>
  3. In the Label field, enter “DraftingScreenMenu-2” 
  4. In the Key-in field, enter ATTACH MENU SampleSM.dgnlib,Menu-1,Menu-1,S1.
    The syntax is:
    ATTACH MENU <dgnlib_filename>,<model_name>,<saved_view_name>,S<n>
  5. Click Apply and save the file.

The above keyboard shortcut should keep the screen menu open in a separate window.

Using the Screen Menus

Now that you have the screen menu created, let us see how to open and use it. There are different ways in which you can open a screen menu:

  1. As a pop-up – We have assigned keyboard shortcut </> to open the screen menu as a pop-up. Pressing this keyboard shortcut should open the screen menu as a pop-up.
  2. In a separate window – If you want the screen menu always open, you can display it as a window. We have assigned keyboard shortcut <]> to open the screen menu as a separate window.

To open the screen menu as a pop-up:

  1. Open a DGN file.
  2. Press </>.
    Observe that the screen menu pop-ups at the cursor.
  3. Click the circle with Place SmartLine icon in it.
  4. Observe that the Place SmartLine tool activates and the screen menu disappears. It will reappear when you press </>.

Once the screen menu is opened, you may also use shortcut key to activate a tool. For example, press <L> to start the Place SmartLine tool.

To open the screen menu in a separate window, press <]>.  The screen menu is displayed in a separate window.

gINT 10.00.00.60 Announcement

0
0

Dear gINT Users,

We are aware of an issue with gINT build 10.00.00.60 which was released January 18, 2018.

This version was pulled from SELECT on March 2, 2018.

The issue affects all levels of gINT (Logs, Professional, and Professional Plus).

You can check your gINT version by going to Windows Settings => Apps and scrolling down to gINT. The version is written there.

If you have version 10.00.00.60 installed, the error involves gINT finding the registry file. Symptoms of the error are:

Upon opening gINT (or closing gINT, a run time error appears.  “Run-time error '-2146233088 (80131500)” appears and gINT closes. Additional information can include

  1. Error in gINT_Software.Library.Settings.UserSettings.Save:Error in .ctor : Access to the path 'C:\Users\Public\Documents\Bentley\gINT\System\settings\registry.xml' is denied.
  2. Error in gINT_Software.Library.Settings.UserSettings.Save:Error in .ctor : Could not find a part of the path ‘C:\...\settings\registry.xml’.
  3. Error in gINT _Software.Library.Settings.UserSettings.Load:Objecr reference not set to an instance of an object.
  4. There may be other variations regarding the registry.

Additionally, it is possible that after closing, there is still a version of gINT running in the background of the user’s PC. This can affect licensing and count as additional license usage.

Also gINT may not run again unless the new registry file is deleted.

If gINT is running in the background of a machine, users can close it from the Task Manager.

The registry error will not corrupt data files.  

The solution, until we post a version with the solution to this issue, is to uninstall gINT version 10.00.00.60 and install gINT version 10.00.00.50. gINT version 10.00.00.50 does not have this issue.

Please know that we are currently addressing the issue and are working to post a new version with the resolution. The updated version will address this specific issue only. We will notify users when the updated version is posted.

If you have questions or concerns, please email me at katie.aguilar@bentley.com. Please include your name, company, contact information, and question/concern. I will get back to you.

Sincerely,

Katie

 

The Benefits of Nonlinear Pipe Stress Analysis Method

0
0

In plant design, it is important to perform pipe stress analyses to examine different loading scenarios, such as thermal, seismic, wind and dynamic loads. This process brings significant benefits, but to understand what those benefits are, it is important to distinguish between a linear and a nonlinear analysis. A linear analysis is characterized by constant pipe properties, small deflections, and elastic deformation when the pipe reverts to its original shape. For example, for every pound of force applied one inch of displacement is created. Initial states are not required for the analysis – all gaps are assumed closed; friction is ignored; linear soil properties are used; and soil yielding is not considered.

A nonlinear analysis is characterized by changes in pipe properties over time, large deflections, and plastic – or permanent – deformations. The analysis is called nonlinear because the amount of force that creates a given amount of displacement is variable. It is important to run a nonlinear analysis because supports that have gaps and friction do not behave in a linear manner. Users gain significant benefits from a nonlinear analysis method. For example, a nonlinear analysis gives project teams the ability to better engineer designs by analyzing more realistic models. State-of-the-art nonlinear analysis engines use tangent stiffness and secant stiffness methods – both of which are found in finite element analysis (FEA) programs such as ANSYS and Abaqus – to handle piping models.

Tangent Stiffness vs. Secant Stiffness Strategies

A tangent stiffness strategy, which handles all the supports and their gaps, involves performing a linear analysis for the nonlinear supports. The starting point equation for the analysis is an initial state. If the support gap in that direction doesn’t close after the initial load case, the support in that direction is ignored. If the gap does close, the specified stiffness is used for the entire analysis. A secant stiffness strategy, which handles friction, derives the initial stiffness from the ratio of support forces – i.e., the friction force – to the support deformation – i.e., the amount of friction slip – and also starts with an initial state. There is some question, however, about whether or not friction should be considered for seismic loads.

According to design codes such as the Uniform Building Code (UBC) and the International Building Code (IBC), friction ought to be ignored – a situation that’s only possible with incremental load case analysis engines. The total load approach offered by most pipe-stress software vendors fails to understand either boundary conditions or how the direction of the pipe movement can change the bearing force. That kind of change can possibly double the stress and load range when, for example, the magnitude of the friction force from an operating condition stays the same when the pipe returns to ambient conditions, yet operates in the reverse direction. Instead, it is better to do an incremental analysis to ensure that no extreme load is overlooked – and to conform with American Society of Mechanical Engineers (ASME) code philosophy.

Using the HoloLens for accurate subsurface utility pipes augmented reality

0
0

The 3D rendering of subsurface utility pipes inside a virtual excavation is cool. But if you don’t have 3D data to support it (e.g. if you don’t know the depth of the pipes), that sort of renderings could actually be misleading.

Users told us that in spite of their limited 3D depth data, 2D pipe maps are very useful for excavation planning, and 2D renderings of those maps in the physical world would be quite handy, even without depth info.

We prototyped that concept using the Microsoft HoloLens and Bentley ContextCapture. We simulated a workflow where a user wants to find a service pipe connection and a valve, and mark their location. Our results are shown in this video:

https://youtu.be/nFSAxMKHNMY

The video also shows that our method enables accurate augmentation of surfaces topography showing significant altitude differences, such as staircases.

Interestingly, our concept could also be extended from visualization to editing.  By projecting existing pipe map data onto the ground surface, our proposed system could let the user visually spot discrepancies between the augmentation and the actual location of surface assets, and propose modifications to the pipe database by “adjusting” virtual pipes location directly on-site…

By facilitating their use on site, Augmented Reality will likely increase the value of existing subsurface pipe maps, and also facilitate their maintenance over the years!

New in MicroStation CONNECT Edition Update 8 - Printing and Publishing to ProjectWise Share

As more and more organizations are using Bentley’s cloud services, improvements in these services are but obvious. The Personal Share feature on the cloud is now deprecated and replaced with ProjectWise Share. The advantage of using ProjectWise Share is that you can share the files with all the team members of your ProjectWise Project (previously called a CONNECTED Project).

This enhancement called for supporting changes in the printing and publishing features in MicroStation. Accordingly, the Publish .imodel to Personal Share and Publish PDF to Personal Share options have been replaced with Publish .iModel to ProjectWise Share and Upload PDF to ProjectWise Share.

Note that these settings can be turned on only when you satisfy the following criteria:

  1. The active WorkSet is assigned a ProjectWise Project.
  2. You have access to the ProjectWise Share folder and have permission to post
