underlay snapping is not working

[Jesto Thomas]

I am using Therm 7.8.77 and am not able to snap on to underlay.

I have used the the same DXF file in an older version of Therm 7.6 and its working.

tips to correct this issue will be greatly appreciated

I assume you have the Snap to Underlay setting checked in the Snap Settings tab?

Hi thomasj

Did you find a reason / solution to this issue?

i have the same problem

(I ave "Snap to underlay" selected in settings) 

Thanks

[Robin Mitchell]

In THERM 7.8.80 (the current version on our website) the snap to underlay feature is working without issue. 

And I am pretty sure it worked in previous versions also. 

Are you importing the underlay as a DXF using the File/Underlay option?

Thanks to you both for your replys

I tried the things you suggested, no change.  

Then suddenly it started snapping today, I have no idea what changed, but it means I can continue

Thanks

Ben

Hmm, very strange. Glad it's working, although it's too bad it's not clear what changed.

Please help  !!

I don't know what I am doing wrong

I have spent all day trying to make progress in therm

I can see how useful this software could be, but I am struggling so much to build basic geometry that doesn't give gap & overlap issues, that I can never really make any progress with the thermal analysis !

  

My Snap to underlay is not working again.

See the misalignment between my orange rectangle, & the horizontal grey Underlay line, 

(and the snap settings I had, I have tried all combinations) ...

So, I gave up with an underlay, and built some basic models with rectangles.

But they are also plagued with alignment issues.  

The shapes snap together as I move them into place (again I have tried all the snap options & combinations I can think of)

But when I try to add Boundary Condition, I get so many red circles,

For example, when I add the left hand elements below, 

They are 2 rectangles butted against 3 other rectangles (of identical width) ....

   

Here it is with the outer left element removed, its flat  

I have tried so many different ways of putting this together

I don't know where to start in listing the methods 

How should I be doing this?

I am using 

THERM 7.8.80   (Downloaded from the website in Jan this year)

Windows 11 PRO 24H2

HP Elitedesk 800 G1 TWR

intel(R) Core(TM) i5-4590 / 3.3Ghz / 8 GB of RAM

I really hope I am being an idiot and missing some very obvious fundamental thing.

Thanks

Ben

Can you provide one of the THERM files that you are having trouble generating the BCs for?
