What free CAD systems are there with the ability to create large assemblies?

Question

CAD/CAM

Hello!
Please advise a free analogue (not student / trial licenses) of CAD, where you can create large assemblies of 10000-20000 parts and the ability to convert to 2D drawings?
That is, an analogue of SolidWorks, Inventor, Kompas3D, etc., engineering parametric, solid-state CAD systems.
Thanks a lot!

Answer 1

absent as a species.
Of the moderately adequate ones, there is FreeCAD, but there can be no talk of tens of thousands of details, because this is clearly an industrial level, which is commercial, which means you can tear off money.
Then, such CAD systems must have a built-in PDM of at least some quality, otherwise you yourself will fall asleep and get confused earlier, even if the hardware pulls such things on an incomprehensible core. Open-source kernels are simply not sharpened for large volumes of geometry. Because, obviously, to write such a class of software, you need a whole infrastructure from competent specialists to banal cooperation with workstation fans and components - you can’t write on your knee. Yeah, drivers for Solidworks are developed in conjunction with DS, Open-source CADs can't afford that.. Siemens, for example, has such an infrastructure. =) I.e. everything that is usable (really usable industrially) costs money. The rest is pampering or torment, as you like.
Of the adequate options - the purchase of Compass. At current prices - 200 thousand for 3D + Graphics and fastener libraries and materials. Quite justified, given that a workstation for such assemblies costs no less. I do not promise stability and convenience of work, but this is a real working option for a minimum of money. Despite its children's sores, the Compass is quite efficient, you can even really conduct industrial production + ESKD "out of the box".
Several times I worked out options for introducing freeware software at machine-building enterprises of various sizes and quality, but the threshold of 5-7k parts did not even cross. It came to the idea of ​​​​running Linux and sticking free CAD on it for it .. I promise you - this is a nightmare. An inoperable nightmare and very expensive in the end - there is no smell of savings on software, it only covers the design costs if it is a private trader who cannot afford to sit and draw some kind of fluid coupling for a month through the efforts of the technicians department.
Not .. but in general there is always a drawing board. You can even find them for free already. The same will happen if 3-4 people of the old school from KB are hired for the cost of software. Not entirely adequate, but if they completely backed up against the wall about licensing, then it’s completely legal.

Imho no.
