Easiest way is likely to create a configuration that doesn't change. Then as long as this drawing references that configuration, anything you change in the future won't affect it.
I think the only way your going to be able to do that is to save the drawing as either a PDF, DWG or DXF file. Saving it as a detached drawing would work as long as that drawing file didn't have access to the model files.
Another option would be to Pack and Go the drawing (or just the assembly if you don't need a new drawing) to a new folder before making any modifications, then make your modifications to the new assembly. And to be on the safe side, re-name your assembly and components during the Pack and Go process.
Detached drawings are designed so you can open and work in drawing files without the model files being loaded into memory or even being present.
To create a detached drawing:
- Click Save on the Standard toolbar (for a new drawing) or File, Save As (for drawing that has been saved previously).
In the Save As dialog box, select Detached Drawing (*.slddrw) for Save as type.
Specify the file name, then click Save.
To create a detached drawing template:
- Click New (Standard toolbar), or File, New.
In the dialog box, click Drawing, then click OK.
Click File, Save As.
In the dialog box, select Detached Drawing (*.slddrw) in Save as type, then click Save.
Click Save As again.
In the dialog box, select Drawing Templates (*.drwdot) in Save as type, then click Save.
In the FeatureManager design tree, the icons for Detached drawings display a broken link:
When a Detached drawing is out of sync with its model, it prints with a watermark that states:
SolidWorks Detached drawing – Out-of-Sync Print
Guidelines for Using Detached Drawings
You can send Detached drawings to other SolidWorks users without sending the model files. However, you can use the same workflow with eDrawings. A benefit of eDrawings is that the recipient does not need a full seat of SolidWorks.
The time required to open a drawing in Detached format may be reduced because the model files are not loaded. You have control over when to load the model, which takes time to load and update the drawing.
If the referenced model is needed for you to complete an operation in a Detached drawing, you are prompted to load the model file. You can load the model by right-clicking a view and selecting Load Model. If the model is unavailable or fails to load, you cannot perform the selected operation. Model files are necessary when you want to:
- Crop drawing views
Break drawing views
Create section views
Flip or change section lines
Insert alternate position and relative views
Insert model items
Detached drawings cannot be lightweight drawings.
Some changes, such as changes to a section line or projection angle, require a view update. When a drawing view requires an update, the view is displayed with a crosshatch pattern.
