As Far as I'm exposed to this kind of engagements and like any other project there are set of tasks assigned to you and your colleagues thus it should not be very difficult finishing your tasks. In case of dependency I've found myself finishing what I can independently finish when my colleague is absent for short duration. For longer announced absence reworking it with project manager and redistribution of tasks always helps. This is healthy for both the project as well as you while the project tries to stay on track and you do not owerwhlem yourselves. For unforseen absence it's as it is very unpredictable and hence focusing on your tasks can atleast help finish up your part. Post that you can take up the colleagues work with PM in CC.

Para garantir que um projeto CAD permaneça no caminho certo, mesmo com a ausência de um membro da equipe, é essencial que as empresas implementem normas e procedimentos rígidos. Cada engenheiro tem uma abordagem única para resolver problemas, o que torna a padronização crucial. Documentar detalhadamente cada etapa do projeto, incluindo decisões de design e alterações, permite que outro engenheiro possa assumir o trabalho sem perder a continuidade. Ferramentas de colaboração e comunicação eficazes também são vitais para manter todos os membros da equipe informados e alinhados com os objetivos do projeto. Assim, a continuidade e o sucesso do projeto são assegurados, independentemente das ausências.

Working on the items that cannot be automated, like part and assembly generation. Other items like drawings, or file exports can be batched generated. Other tools like cloud simulation or rendering can happen simultaneously, while other team members focus on the detail work. Calculations can also be automated to a certain extent.
