https://communities.bentley.com/products/building/performance/f/hevacomp-forum/172135/questionHi there, Is anybody knows how to find lost data of dxf? I traced the floor roof etc. all done and a new user who doesn&#39;t know how to use hevacomp create a second dxf file on his computer and start tracing and all of my job gone. Nothing remains dxfen-USTelligent Community 12https://communities.bentley.com/thread/495995?ContentTypeID=1Mon, 10 Dec 2018 16:51:25 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:cb388952-4829-4cef-84e1-dcc139392dfbNektarios (Nek) Ktorides<div dir="ltr">Thank you! <br /><div>Yes you answered my question</div></div><br /><div style="clear:both;"></div>https://communities.bentley.com/thread/495992?ContentTypeID=1Mon, 10 Dec 2018 16:37:52 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:e6a582c9-c97d-4466-8e95-f9ba7062f20bDuncan Brown<p>When you select a DXF file for a Design Database project, a new file is created in the project folder with a DXF.CACHE extension - for example, your DXF file is called FLOOR1.DXF, then FLOOR1.DXF.CACHE is generated in the project folder, and it contains the polyline information that the program uses. It shouldn&#39;t matter if the DXF is moved, as the program will read the DXF.CACHE.<br /><br />Regards,</p><div style="clear:both;"></div>https://communities.bentley.com/thread/495978?ContentTypeID=1Mon, 10 Dec 2018 15:46:01 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:3669f17c-0b77-440c-8cba-703a73b1e184Nektarios (Nek) Ktorides<div dir="ltr">Duncan,<div><br /></div><div>Can you please tell me if any person removes the dxf file which is already traced and then he copy it back then all back to normal?</div></div><br /><div style="clear:both;"></div>https://communities.bentley.com/thread/495957?ContentTypeID=1Mon, 10 Dec 2018 14:29:17 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:3cfda23d-f58e-4fb7-839b-489bb593410eDuncan Brown<p>Ok - thanks for letting us know.<br /><br />Regards,</p><div style="clear:both;"></div>https://communities.bentley.com/thread/495956?ContentTypeID=1Mon, 10 Dec 2018 14:28:24 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:96eaa251-6076-4421-a6b6-77696daabfc1Nektarios (Nek) Ktorides<p>is ok i sort it</p><div style="clear:both;"></div>https://communities.bentley.com/thread/495949?ContentTypeID=1Mon, 10 Dec 2018 14:08:05 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:0880ebdf-7cde-4874-a556-6057a1532e2aDuncan Brown<p>In CAD Input, there is an option in the Zoom menu called &quot;3D building view&quot; - If you switch to that view, can you see your building?<br /><br /><img alt=" " src="/resized-image/__size/320x240/__key/communityserver-discussions-components-files/275871/3d-view.jpg" /></p> <p>Regards,</p><div style="clear:both;"></div>https://communities.bentley.com/thread/495948?ContentTypeID=1Mon, 10 Dec 2018 14:03:53 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:c538e463-3081-4bc7-b86b-7641d8035b5bNektarios (Nek) Ktorides<p>Sorry i didn&#39;t&nbsp;get it?</p><div style="clear:both;"></div>https://communities.bentley.com/thread/495947?ContentTypeID=1Mon, 10 Dec 2018 14:00:36 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:1f94e534-0024-4562-9d12-838f1cdaec10Duncan Brown<p>Hi Nek.&nbsp; Can you still your building if you look in the 3D view?<br /><br />Regards,</p><div style="clear:both;"></div>
