A CADProps share link is for reviewing one finished 3D model in the browser. It is a fixed viewing snapshot, not a delivery of the original CAD file. The owner must sign in to create the link; the recipient does not need an account to open it.
Check the model before sharing
Open a supported 3D file and wait until processing succeeds. Confirm the expected parts, orientation and units in the workspace. If an assembly is incomplete or a mesh result is approximate, tell the recipient what the displayed model actually represents. Two-dimensional drawings, multi-model workspaces and comparison results are not shareable as one link in this release.
Select Share. If you are not signed in, complete the login dialog first. CADProps saves an eligible guest source into your account before creating its share; the file and its snapshot must fit the account's limits. If the source cannot be saved, resolve the error rather than assuming a link was created.
Choose the link settings
The free link lasts 7 days, enough for a short review. When the recipient needs more time, choose 30 days, 90 days or 1 year; that makes it a Pro link, which uses 1 point once (pricing). The viewing page shows the expiry. A password of 6–20 characters is also a Pro link option. Send the password through a separate channel; it is not embedded in the link and cannot be recovered later.
Copy the link that appears when the share panel opens. Up to 10 active links are allowed per account, subject to the 200 MB storage limit; one of them can be free, and while it is in use each further link is a Pro link. An optional public preview can expose a title and cover image without the model password, so leave it off for private work. See how previews and access work before enabling it.
Test what your recipient will see
Open the link in a separate browser session. Confirm that the correct model loads, the optional password is required, and the expiry is suitable. A recipient can rotate, section, inspect properties and measure using the supported viewer tools. Saved annotations included when the snapshot was created are readable, with recorded viewpoints; recipients cannot edit those notes or reply. Editing the owner’s local notes does not update existing links. The original CAD file is not offered for download. Share only with people you trust with that view.
Uploading a newer model does not update an existing snapshot. If a new revision replaces the old one, create a new link and identify the revision in your message. For a supplier who needs STEP or native engineering source, deliver that file through an agreed transfer method alongside the viewing link. The supplier handoff checklist covers that distinction.
Keep control after sending
Open My shares in My files to review or stop active links from another device. You can also manage links in the workspace. Stopping a share blocks later access through CADProps; deleting the saved source file also revokes its links. Neither action removes screenshots or files someone already kept. Read the link-management guide for those cases.
Resolve creation failures before you send anything
If the Share dialog cannot create a snapshot, check three things in order: whether the current view contains one eligible, successfully processed 3D model; whether you are signed in; and whether its source and snapshot fit the account limits. A completed upload does not by itself satisfy every sharing prerequisite.
An incomplete assembly also needs an explicit review decision. You may be able to inspect the loaded geometry, but the link should not be described as the full assembly. If completeness matters, obtain the missing parts before starting the external review.
For a supplier review, prepare a short message stating the revision, purpose and scope: for example, “Revision B geometry review; confirm the mounting interface; engineering source supplied separately.” This is a suggested message, not an automatic notification or a manufacturing approval.
Check the copied link as a recipient after creation rather than relying on the owner's signed-in workspace. Confirm the optional password challenge, available controls and the intended notes. Download your own source and keep the controlled engineering record separately if the review must outlast the link's expiry.
