Second time trying to resolve this..my previous form post from 2022 has been deleted and the issue is still unresolved.

Heres the problem.. Spaceclaim 2020R1 is usesless for working on drawing sheets once you have around 45 or more. I have a model which is 126mb and has 50 drawing sheets. With just one sheet open It becomes impossible to add dimensions, notes etc or move views, when you have reached this number of sheets. It appears that spaceclaim has a memory leak or memory issue when a model contains a certain number of drawing sheets. The memory usage continues to grow even when idle.

The same behaviour was verified by my local distributor and it was logged as an issue by Ansys Spaceclaim support back in October 2022. I have not had any feedback since. The issue was also evident in spaceclaim 2022R2 (tested) 16gb & 32gb ram

The only way to work around this is to create a copy of the model and delete all the drawing sheets and then add new sheets. The problem with this is that you cannot reference earlier drawing sheets while working and if you make a change to the new model, the previous model is incorrect.

If anyone has any suggestions or fixes you comments would be welcome.

Thank you.

Hello Nigel,

If you have more numbers of sheets in the file, it can get slow to work with. The workaround will be to have copies with lesser sheets. Let me see if I can find any other workaround, although in my opinion this is the current limitation with the product.

Hello,

Thank you for your resonse. Having copies with lesser sheets is a work around but not ideal, since the model will be continually modified or revised. What would be great would be the ability to 'suspend, suppress or archive' completed sheets so they do not take up rescources, allowing work on new sheets.

Best work around is to have the model you are continually modifying as one file, and then insert it into a new file as a component to create an assembly and do the drawings in there. If the drawing sheet qty is the issue, then only do a few drawing sheets in that file. Then repeat by creating a new file, and insert the model again as a component to do some more drawings. That way any changes made to the orginal componet will be reflected through all subsequent files used to hold the drawing information. It also means when you want to do mods on the gemometry, you don't load a single drawing into memory so your modelling will run smoother.

As far as memory leaks go though its not only drawings, see this post, Memory leakage, freezing slow performance (ansys.com), and this one Reply To: Space claim files grow in size… (ansys.com)

Thank you for your comments and suggestions. I will try this in future. I wish I knew this previously. I have a model which I need to make changes to, it has 51 sheets and is unworkable. I have copied it and deleted the drawings then made changes to the copy and added new drawings but obviously have 2 models which are not in sync.
