Customer Reviews

They explain it better than we do

Mohammad Aghababa 11 months ago

I had a great technical support session with Alan and Léo from Ohmycad. They explained clearly how to save files on 3DEXPERIENCE and manage revisions with the maturity cycle. The session was very helpful, professional, and easy to follow. Looking forward to the next one on automating the drawing title block. Highly recommend their support team!

Frequently asked Questions

CATIA 3DEXPERIENCE Frequently Asked Questions

Is CATIA only for large corporations?
No. On 3DEXPERIENCE, CATIA is available through subscription-based roles: an SME or mid-sized company can equip only the engineers who need it, without oversizing the solution. And Ohmycare support provides you with a dedicated engineer, regardless of your team’s size.
What is the difference between CATIA and SOLIDWORKS?+
SOLIDWORKS covers the vast majority of 3D mechanical design. CATIA takes over for projects involving complex surfaces, where systems engineering is central, or where assemblies are very large—in other words, where SOLIDWORKS reaches its limits. To decide which is right for you, read Our CATIA vs. SOLIDWORKS Comparison by Industry.
How do I switch from CATIA V5 to 3DEXPERIENCE?+
Preparations for the transition are underway: data migration, continuity of methods, and team training. Ohmycad manages each step to ensure a smooth transition on a project-by-project basis, without interrupting production.
Does CATIA run in the cloud or on-premises?+
Both. On 3DEXPERIENCE, you can work in the cloud or locally depending on your needs, with real-time collaboration around the digital model and licenses that are always up to date.
How many roles are needed per engineer?+
A role corresponds to a scope of work. An engineer may have only one role, or may combine several roles depending on the project. An Ohmycad engineer determines the most appropriate combination; pricing is based on the quote.
