Hi, I think some improvement on Import Menu will be user friendly. When we import some content from a file (*dxf etc.), it will be good to be able to select "into which stages" the import will be taken place. A multiple selection box will be handy. C.

That's good to learn. It seems to be the answer I've been looking for. Thanks Martin. C.

Hi, It does not allow you to change the leakage for a part of the duct eventhough you specify some leakage when the duct is built. Attached file "1" is the Duct Edit box when we select the entire duct. It allows you to modify the Leakage Porosity. Attached file "2" is the Duct Edit box when we select some parts of the duct. It doesn't allow you to change the porosity. The reason we ask this to be enabled is that as I said in my earlier post, a branch of a duct network sometimes needed to be modified hence its leakage porosity changes. The suggestion for leakeage and offset is just to make the software more user friendly, in any case if it doesn't change, we always rebuild the duct to be certain that we don't accidentally detach something. Thanks. C.

Hi, We can't modify a vent duct line's Leakage Porosity, Leakage Intervals etc. as shown in attached picture. In underground operations, we sometimes need to change intervals of a branch of vent ducts or some portion of vent duct leakage porosity is better or worse than rest. We need to partially modify leakage porosity, intervals etc. (in short, grayed attributes) of vent ducts. In addition to this, it would be useful to modify the offsets of a vent duct as a group. In order to change the offset, we have to remove the vent duct, re construct it. Thanks a lot. Regards, C.

Hi, Just a quick update that may affect on the solution. The vanished airways seem to be the ones which we last edit on previous SAVE. For example, if I remove an obstruct/regulator or something over airway ID 650, or modify the settings of a fan working on airway ID 700, the next time I open the file airways ID650 and 700 vanish. This seems to also lead to the Airway Shape Randomly Changes Bug as well. I hope this can give an insight to the bug. Regards, Cihan

Hi Craig, yes I use the latest version 5.4.0.5 and I have just sent you the model. Thanks. C.

Hi, In my model there is a rounded shaft with 8m diameter. However, when I simulate, VentSIM automatically changes it to 7,16m. No matter what I do, fix it, save it and re-simulate, It converts it back to 7,16m. Interestingly, there is a question mark next to the Diameter attribute on EDIT box, when I click on it a pop-up comes and it says: "Number Unique 200458 : , Length 799,9 m 8,0 m Diameter Current Size Dimensions 4,3 m Diameter Recommended Size Dimensions Click window for more information" This is a fixed airway already excavated and I cannot change it. On previous versions of VentSIM this didn't happen. Thanks. C.

Hi. In the preset value Tunnel Type window, there are width, height, perimeter and area information listed as columns to assign profiles. However, there is no diameter information is given as columns for the rounded airways. This can be added. Thanks. C.

Hi, I confirm that I already selected attributes I want to clone.

Hi, It would be useful if the software lists the customized airway shapes inside Settings page. It shows only pre-defined ones and "Custom" title but there a couple of customized shapes in some models. Thanks. C.

Hi, Clone attribute feature is not working and "cloned attributes pop-up window" does not disappear for a long time after I cancel the feature. v. 5.2.8.5 x64 Thanks. Cihan

Hi, As seen in attached screenshot, when I open my VentSIM document, I see some airway shape changes back to another shape randomly. Using v.5.2.8.5 x64 Thanks in advance. C.

Hi Martin, This problem still occurs with the most recent version. I have sent you the model for your check. Waiting feedback. C.

Hi. When we assign an obstruct or Backfill value for an airway, it used to change the Area of the airway. Consequently, we suppose to see the change in Q, V, R and P loss values under Simulation area of EDIT window. Now nothing changes. Using version 5.2.7.2 x64.

It seems to be fixed with the update. Thanks!
