But I'm not able to create a rule to collect all pipe feature of the assembly.Do you know how to do? The figure shows two other examples of symmetry lines. Because the symmetry lines all overlap, they will be merged. Your advice worked, I was able to make them disappear in the drawing. When you dimension center lines and then make a modification, the dimension is automatically updated.

Hold Middle Mouse Button + Shift key and move the mouse to pan. There are a few things you need to do to make sure the pipe centerlines don't show up: You might also have to take a look at your layer settings in both your 2D drawing and your 3D model.More details here:https://www.ptc.com/en/support/article/CS44077. Learn Part Modeling in Creo Parametric - BrainBell - Click "Import/Export" "Import configuration file" at the bottom left corner of the "Options" window. In A, the symmetry lines are found by clicking the pairs of lines that define them. I hid all the piping lines and that makes no difference. Copyright 1998-2023 engineering.com, Inc.

Inventor change origin axis - sabines-berner.de I have always used layers for this. To create a symmetry line (or other symmetrically associated object). Set drawing setup option hlr_for_pipe_solid_cl to yes (to piping feature, hide the pipe part and check the centerline of piping feature) You might also have to take a look at your layer settings in both your 2D drawing and your 3D model. New member. To create a diameter, move the pointer to the far side of the centerline. Creo won't hide the solid geometry when you add the feature to a layer but it will hide the centerline.
