I need to import an AutoCAD DXF file into QGIS. However, I'm running into problems with the CRS. The project CRS is EPSG:4326, the OSM Standard I'm referencing is EPSG:3857, and the projection from the DXF file is EPSG:2277 (TX83-CF in Civil3D). It seems that no matter what I do, the data never ends up in the right location. What I've done: * Georeferenced the file using Another DXF Importer and adding the coordinate system when prompted (ends up in the Pacific Ocean in the right latitude but wrong longitude) * Imported without georeferencing using Another DXF Importer (again, right latitude but wrong longitude) * Changed OSM Standard projection to EPSG:4326, 2277, and 26914 (ends up at 'Null Island', the white void, and the Middle East) * Changed the project projection to EPSG:2277, 3857, and 26914 (stays at right latitude wrong longitude) I'm pretty sure I'll have to modify the DXF file in order to fix this, but truly I'm grasping at straws. One of my coworkers helped me to find the solution! It turns out that the file was supposed to be in NAD27, not NAD83. The correct projection was EPSG:32040.

<p>We use the USDA NAIP photo mosaics in dwgs. We've never had a problem with them until the new 2025 photos came out. They are the new version of Mr. Sid. We've reached out to Autodesk on this issue and a team member sent this reply.....</p><p>I apologize for the inconvenience caused by this issue.<br /><br />Civil 3D does not support 4th-generation MrSID .sid files. Only older 3rd-gen SID files are supported. There is currently no patch or confirmed update from Autodesk to add support.<br />To use the image, you must convert the 4th-gen SID to GeoTIFF or JPEG2000 using GIS software, then insert it into Civil 3D.<br /><br />Please keep me updated on this issue. Rest assured that I will always be here to help you along the way.</p><p>&nbsp;</p><p>Has anyone figured out a workaround or solution for this? If so, what software have you used?</p><p>Thanks so much in advance for any and all advice.</p>

<p>Hi all, we are moving over to Civil 3D 2026 and i am having issues getting the Plugin to load now in Civil 3D 2026.<br /><br />I have Deleted all my Plugin References to 2025 and reimported the 2026 References and have also changed this:</p>&lt;RuntimeRequirements SupportPath="./Contents/Support" OS="Win64" SeriesMin="R25.0" SeriesMax="R26.0" Platform="Civil3D" /&gt;<p><br />i have also tried R26.0 at both and still doesnt want to load .Dll's.<br /><br />Am i missing something for 2026?&nbsp;<br /><br /></p>

Is there a way to disable the plot command from defaulting to last saved location without changing SDI to 1 and re-opening cad for each drawing? We prefer working with the sdi=0 for the tabs but even with a lisp command to change the default plot location to the dwg location it is over-ridden by the last plotted location.  (default folder is updated but ignored by the dialog box after any plot has been made successfully because civil3d forces it to the last saved location) I have attempted to get his to work with a lisp in 2023/2024/2025/ and 2026 versions and it does not work for any of them.

Hi, When I use the Export Civil3D Drawing, loads of frozen layers appear in the standard CAD file. Even when I export a "layer state" from the 3DC viewport and import into CAD, it does not work. Loads of unwated layers visible and a lot of time tidying up the drawing to make it presentable. Is there anyway to fix this issue? Also, some labels loose their elevation value when brough back to CAD? What would be causing this? Thnaks in advance

I've been playing with the new pond feature in C3D 2026 but haven't been able to find an elegant way to add it to a surface. I saw you can have auto feature lines linked to the pond but was wondering if it's possible without creating them and then manually adding to a surface. I'd like to create the pond and be able to show it in profiles and section views but this doesn't seem to be an option yet. Anyone had any luck adding the pond to a surface?

Dynamoにて、横断ビューを作成しましたが、モデルが反映できていません。 自動で横断ビューにモデルを反映させる設定を行いたいと考えています。 反映するモデルについては、Dynamo内で指定できる状態です。 このため、Pythonscriptノードに反映したいモデル情報を入力した状態から、 実際に横断ビューに反映する処理をどのように実現すればよいのか、 設定や手順についてご教示いただけますでしょうか。 よろしくお願いいたします。
