Hi Kevin, If you can tell me what you've tried? See below image.. 1. I've clicked on the tool bar button to set the background image (selected an image file) 2. clicked on the pencil and use the mouse to left click on the bottom left (see the red dots, i'm part way through building this shape) 3. click save and we have new shape, note: no need to close the shape it will automatically connect the last dot and first dot (the green line) Let me know how you go Note: you can also copy and paste the points from excel Regards

Hi Mick, Thanks for the comment, I think it does take some time getting used to, but I like the consistency of the new layout the most. We've had a few people really dislike it, who have persevered; and after a while actually start to like it. They went back to an old model using previous 5.1 and found it hard to use. We think its a better solution in the long run and gives more flexibility, however we will continue to support the old layout and keep the option there. So it is simply a user preference, if you like the old, stick with it no worries, its just a choice of interface style. New users find the new layout easier to use, so will be the default for new users. Don't worry we'll continue to support the old style and keep it up to date so you won't miss any new functionality using it. Hope that helps allay any fears. Regards & thanks for the feedback

New Design for Editing airway properties VentSim 5.2 introduces a new layout for the editing of airways. We believe the new layout makes it easier to learn, more consistent, intuitive and generally easier to find and edit the property you’re looking for. We’ve tried our best to design the new layout to be very similar if not identical to the old layout. i.e using the same grouping and order of properties, the same number of tabs and icon designs. Why change a perfectly good system? Because some of our users requested it We’ve had quite a few users, requesting us to modernize the UI and clean up what can be viewed as a somewhat cluttered properties dialog Other Benefits Hiding and collapsing of the different categories (see screenshots below) Consistency across tabs Layers are all grouped together Better support for multiple languages Using a grid will give us more flexibility in the future to allow people to customize which rows to show and hide, some users have also requested to be able to dock the different tabs, so you can view the different tabs at the same time etc.… Mixed Reaction from our users Change can be tough, and the new interface does take some getting used to. But after the initial reactions of “What the!” We’ve got some good feedback. But don’t worry if your one of those who likes the old design and would really prefer to stick with it. We’ve got you covered! Just switch back to the old one… We’ve made it ultra-simple (See screen shot below) just right-click and select “Switch to Old Edit Box…” and if in future you’d like to give it another go in the future, just right-click “Switch to New Edit Box…” New change coming today! A couple of people have suggested some changes to simplify the resistance selection to reduce number of clicks required, now you can just drop and select the pre-set instead of needed to select the pre-set category first. (see screen shot below) Right click and select “Switch To Old Edit Box…” The New vs The OLD Improvement when selecting Resistance in the latest patch out later today!

Hi Kingsley, We've put out a patch release, which includes a fix for the fan Tab Please install from http://www.ventsim.com/download/minor-releases/ Issues Fixed in 5.2.6.3 Correctly update saved Views when inheriting a model Added Vertical scroll to fan tab, when display is small Intermittent crash turning on and off icons Modify sorting of preset values to follow sorting in preset table Fix to fire simulation density setting with extreme temperatures Regards

An updated feature in VentSim 5.2 is the new advanced spreadsheet We've updated the old Spreadsheet tool, the new spreadsheet tool has the following new features 1. Advanced Equations to Filter values 2. Grouping 3. Save multiple custom views For example create a filter to select velocities > 2 AND < 20 Select from available operators Select logical operators between rules (AND, OR, etc...) Drag a column and drop in the header to group rows according to the column i.e drag velocity average and drop it in the header to group airways according to velocity Save your custom views, using saved views list box

A new feature in VentSim 5.2 is a new docking panel called "Model Explorer" This is designed to quickly allow you to navigate to different items in the ventilation network. To access this view go to Tools | Model Explorer Menu This will open up the new docking panel, by default this is docked to the left of the screen. The model explorer will list all fans, fixed flows, regulators etc.. that are currently being used in the model. To quickly navigate to a fan for instance, you can double click on the fan and the 3D view will center on the fan. In the below image the AFN fan has been selected (double-clicked) and the 3D graphics has focused on the fan To modify the display options right-click and the below context menu will be displayed By default the list is sorted by elevation and grouped using primary and secondary layers Model Explorer is a quick way to navigate around unfamiliar models, please let us know if you find this new feature useful.

A new feature in VentSim 5.2 is the new custom shape builder, making it easy to create custom tunnel profiles Navigate with-in VentSim to the Settings | Presets menu, and select Tunnel Profiles Create a new profile and click on the profile image, and the new custom shape builder will be shown. Select an image to trace over and save, note: the last point will automatically connect to the first point. The result of this example is Note: 5.2 includes a new default profile shape called semi-circle

Hi Garrett, Thanks for the feedback, yes we've been recently working on tablet mode for Vent Log our application for collection survey information underground, and as such we we're thinking about updating the VentSim touch controls (as you said these are a bit out of date) We'll let you know when we have an update ready... Thanks!

Hi Kingsley, Thanks for the feedback, there should be a vertical scrollbar when it gets too small to fit the screen... We'll look at adding it and putting out a patch. Thanks!

After talking with Surpac support they just need to make sure they save to text not binary format. Customize>Plug in Preferences click on the Surpac tab, and tick the box for text Restart Surpac. You will now be able to edit the string file like in previous versions.

A new feature introduced in VentSim 5.2 is a new way of applying changes to a specific stage(s). In the below example a fan will be installed in the airway in a future stage (production) but in the preliminary stages the airway has no fan. Step 1 – Select the airway Step 2 – Make the changes required i.e add a fan to the airway Step 3 – Instead of clicking apply (which applies to the current stage), Go To Tools Menu and select “Apply to Specific Stages…” (see below) A small dialog box will be shown, and you need to select which stage(s) the changes will be applied to. Step 4 – The result In the Preliminary Stage (i.e no change) AND In the Production Stage (a fan is located on the airay)

Hi Risto Thanks for letting us know, if possible could you please send the surpac file to support@ventsim.com Also check if your using the latest version of 5.1 we've fixed a couple issues with the importing a while ago, so I'm hoping this one has been fixed. Thanks

Hi Addy, Could you please send me a copy of the Surpac file if possible, I've checked a simple surpac example in the current release works ok.. perhaps the surpac file format may have changed... Thanks for you patience
