  • Not picking up a CAD surface (v4.2)

    Im trying to setup a scan or create a regular old vector point on a surface and when I click on the CAD surface nothing happens. Other surfaces seem to work on the model. I have no idea what Im doing wrong here?

    I need the surface data to get my alignment to work out.

    Surface mode is selected.

    The model was imported from IGES.

    Mr. Comment,

    You may not be doing anything wrong. I have had cad data in the past (both iges and step format), where not all the surfaces were there to be able to select.

    I know that this may not help you, just wanted to point out the fact that you may be doing things correctly.

    Best Regards,

        Had the same today: some surfaces were good to create UV, some not on the same model(stp).
        My case is mirrored model. Original works fine, copy wouldn't create path even surface turned black( no U,V pointers).
        Turning Surface Mode on/off didn't help.
        Recreating Mirrored Copy did the job, now it seems to be OK.
        Try reloading model.

          Not sure if this will help, but did you toggle between surface & wireframe

            Tried that, surface flashed black when I click but the "probe" never picks up the surface.

            Guess I'll have to try reloading the CAD to see if that helps.

              I dont have any wire frame data to toogle to. The option is greyed out.

                Maybe create a layer, and hide everything BUT that layer. then you can select it. Works for me when I have that prob...

                  I have seen this in many versions. Usually I can get a hit if I rotate the CAd such that it is almost perpendicular to the viewer and then try to click near where you want. Doesn't always work and sometime not pretty but it gets you through the scan/point for alignment.

                  Or, if you have the native file output it as IGES alternative or Step?

                    When that happens I usually find that the vector direction of the surface is swapped and and you'll actually pick through the surface you want to the next one below it. I don't know 4.2, but if you set that surface as a priority surface you SHOULD be able to pick it and then SWAP vectors on it and use what you have loaded.

                      Bill Thanks for reminding me.

                      There is also a "fix cad vectors" option in 4.2. Go to I think "operations and there is a "fix cad vectors option" open that, and box select the cad model, click on fix vectors and then ok. It may not be the answer in this case but try it.

                        Try picking a point right in a corner of the surface you want, sometimes this works and you can then pick where you want your point to be

                          I had this problem when I went to V4.1 from V3.73. We used STEP and had to switch to IGES. I make my own models to import from ProE and always pick to export surfaces and curves so I have both. Ask the engineer to recreate it a different way until you get it to work. What modeling software was used to create the model?
