Trying to import dxf file and keep getting 'error while opening file' message, can you advise.


madoniaivan 2020-09-28 17:26:04

Hello Sir
Thanks for contacting Us.

This import issue is usually related to the graphic properties of the dxf/dwg which can contain some non identifiable objects. we can try to solve the issue simply by:
- open the file in your CAD software
- select all and execute the "explode" command;
- delete any unnecessary texts (measurement, notes, etc. etc.)
- delete undesired lines, stray graphical elements and any other graphic which are not part of the Thermal Bridge structure that you need to calculate.
- save the CAD drawing file (possibly in a older file version e.g. DWG2010, DXF2010)
- import the new CAD drawing document in Termus Bridge

Please let Us know if you need any further assistance.

Ok that worked thanks, now keep getting message
'access violation at address 5054E110 in module 'ig9icd32.dll'.
Read of address 00000A4.

'access violation at address 5054E110 in module 'ig9icd32.dll' is caused by INTEL embedded Video Cards present on LapTops. Please try updating the Video Card Driver.

You should be able to find helpful info here:

Let us know how it goes.

Best Regards

Thanks for your feedback!
It would be very useful, at this point, if you could provide your System details.

See Figure to export your PC configuration - Then I need you to save and send me the file here.

The issue is definitely the Intel onboard Video Card - infact the .dll library is distruted by Intel.
Now, although we support low performance cards in TerMus BRIDGE, there's still some issue that needs looking in to. If your LapTop has a Second Card (AMD/ATI or Nvidia) please also check if you have a driver software that allows you to select it for use with TerMus.

Anyway, please send me the PC config file and we'll take it from there.
I'll add an extension to your Subscription to make up for the period of non-use.

Hi, I'm really sorry but the file you sent doesn't come from TerMus-BRIDGE.
I need that .rtf file in order to see where the HW problem may be.

Please send that over as soon as you can.



Tony 2020-09-30 09:47:57

Now I can see your PC specs!
The Problem is definitely the INTEL onboard Video card and the driver software. That certainly needs to be seen to in terms of driver updating and is currently causing the .dll to crash.

I also see that you have a second card: NVIDIA Quadro P620 which I would prefer to use with TerMus.
Now you need to check out your Nvidia driver software and FORCE it to be used when running TerMus.

Please check out if you can find a section such as in this screenshot and set TerMus to use this card.

Please let me know if this does the trick. If you're still encountering issues, we'll set up a remote assistance session for you!.

Hi Barry,
Now that we've got over the first obstacle, I can see you're now moving on to producing the report, I need you to Uninstall TermUs and then Reinstall but with your AntiVirus temporarily in SUSPEND mode.

After Reinstalling, run the software just once as ADMIN (right mouse button click on the Program Icon -> Run as Administrator) and if it runs correctly, you can reactivate your Antivirus.

With regard to importing CAD drawings, you can use them as a background to trace the TerMus Thermal Bridge related objects (Bounday, Material Layer, Ground).

After that, I would suggest removing the CAD drawing and then moving on to the calculation phase and production of the report.

Hi There
It's Ivan here,
Have you try to select the dxf drawing reference and then press the "delete" key from your keyboard?
please let us know if this works


Tony 2020-10-01 10:27:55

of course. I'll follow up with step by step help but need youto send me your TerMus file.
It's probably the Adiabatic contour lengths (Ground section) that are set to zero.

The fact that you are getting an out of memory error is again linked to the video Intel Card. Are you sure you're using the Nvidia Card now??

Please send in your file at your convenience.



Tony 2020-10-01 16:42:40

Hi Barry,
I'm still in the process of checking the file because there does seem to be a modelling issue. However, my compliments because you have correctly assigned the Material characteristics to the wall material layers and the Window Frame elements too.
The only thing missing at the moemnt is the Climate data (Assuming it's Omagh) in the General Data tab below.

Please be patient while I check out why it's going out of Memory.



Tony 2020-10-02 16:28:09

Hi Barry,
sorry to keep you waiting.

I've had a look at the file you sent and it seems to be modelled correctly. The only problem is that it's corrupt in a section of the data stream which causes the Thermal Bridge calculation to crash.

I've sent it over to our Dev team for debugging and to see what's wrong and where.

I'm afraid that you'll have to re-model it again if you're in a rush to carry on with your work.
All I can say at this point is that the file was probably saved when one of those exception messages came up.


Tony 2020-10-05 17:41:29

Hi Barry,
believe it or not but we were just taking a closer look at the file.
I just discovered that the Thermal Bridge was modelled correctly but the scale must be wrong.
I believe your intention was to model in mm but ended up modelling each part of the TB in meteres.
You can immagine how large the Calculation becomes when taking in account such large dimensions.

Can you please remodel it in mm or cm simply keeping your eye on the dynamic measurement values as you are tracing the various material layers?
After that, TherMus will surely be able to provide a full Thermal Bridge calculation and the relating report sheet too.

Sorry for the delay but I only just noticed!



Tony 2020-10-06 14:45:22

Hi Barry,
Default measurement system is in meters. Any reference to other thermo-physical characteristics are shown in the panel on the right. Normally all in [mm].

With the Errors you are receiving duraing the calculation. try setting the BOUNDARY type to Internal or External and run the calculation to see what or if any errors remain. If you have elements that are in contact with the ground, we normally set it to "Adiabatic" and then define a boundary calculation section length as you can see in the attached figure.

However let me know how it goes and if necessary send me the correctly modelled file over for a quick check.



Tony 2020-10-06 15:17:23

Here's an example Report for you to look at.
