Just that. By good I mean something at the level of SolidWorks, AutoCAD, or similar. This is a complete limitation for me (and many others) to use Ubuntu.
Not exactly the same as Solidworks or Autocad, but it really depends on what you are going to do. Reviews says that many free software do have good quality, but unfortunately that's really subjective.
It is a good and professional CAD Solution. It is available for Ubuntu. Since it is not OpenSource you can download a free trial version, it will works just like the full version for a period of 30 days. Require registration before.
LibreCAD is a free Open Source CAD application for Windows, Apple and Linux.LibreCAD is available in the Ubuntu Software Center. LibreCAD is an application for computer aided design (CAD) in two dimensions (2D). With LibreCAD you can create technical drawings such as plans for buildings, interiors, mechanical parts or schematics and diagrams.
DraftSight (not free software) is the only native software running on Ubuntu compatible with DWG files - it's 2D only (can view 3D files but not create them), sort of an equivalent to AutoCAD LT.
If you want to spend money then
Bricscad is a lot more powerful, has ACIS modeling just like AutoCAD (Pro version) and its Platinum version has even parametric modeling.
I use qCAD for simple architectural drawings. It is only for 2D CAD. I find it excellent, better than AutoCAD, for my purposes. The documentation is good and the project continues to be maintained.
There is a community edition with limited features, or you can pay for the "professional" version (which I use), currently 33 EUR. The latter fully supports dwg and dxf formats.
two good choices:
1: FreeCAD, free and opensource, native born to linux, but not as functional as, not even close to solidworks, not to mention siemens nx or catia.
2: onshape, which is cloud based, running on webbrowser, which is comparable to solidworks in functionality, and which is actually made by the original/early founder of solidworks when solidworks refuse to adopt his advice to move everything to cloud. Price is also comparable to but less than solidworks.
by the way, autodesk fusion 360 works both on windows and macos if you only hate windows.
Bricscad is a 2D CAD and 3D direct modeling. This software have three licenses models offering different prices. You can download a free version without license key for a 30 day trial period. This version is received via an email.
Ok so its not strictly speaking a native Linux application. But it runs under Wine. Is very powerful and very easy to use and most of all is completely free.
"At level of Autocad" means commercial software. Best commercial software. I used many CAD programs in both Windows and linux, and my assessment for linux is like this:
Closest Autocad equivalent is Bricscad.
Second place goes to ARES Commander and CorelCAD.
Third place goes to DraftSight Pro (because it got video card issues on nVidia cards).
Solidworks is NOT CAD, is PLM (product lifecycle management). Best equivalent for Solidworks could be Siemens NX. Others may say CATIA, but CATIA lost linux support back in 2008.

You could try FreeCAD or BRL-CAD or some of the other floss alternatives.
VariCAD
It is a good and professional CAD Solution. It is available for Ubuntu. Since it is not OpenSource you can download a free trial version, it will works just like the full version for a period of 30 days. Require registration before.
DraftSight
DraftSight is a DWG files 2D editor and it has similar environment as AutoCAD.
It is free of charge but is not Open Source.
Check out these 2Doptions.
