Selecting only lines passing through a plane
Read 182 times

Hi folks. I am trying to select edges of faces or ends of lines which are perpendicular to the work plane (i.e. Passing through the plane) so that I can draw a section for lofting.
Is there an easy way to do this.

If you switch to a view that is not normal to the workplane, it should be easy to identify the lines you want.

Thanks Henry but the model is very busy with lots of features. If there was a way of selecting items that are only on the work plane it would be easier.

Hi mattygreen,

I would suggest that you put the lines etc onto a separate layer and the rest of the drawing (if not already on separate layers) onto layers other than "0" 
Then deselect everything that is not on the lines layer and it should be easy to do what Henry suggests.

Layers are one of my favourite features in TC.

Maybe more easy to choose "Select by >> Layer", rather then select and unselect x numbers of Objects/ Layers.

Or close all layers except the one's you want to use for drawing the object, AFTER the workplane is set

Do you mean the edges of 3D faces that pass through the plane?  Edges of faces that pass through a plane can be determined by drawing a profile on the plane around the extents of the drawing, making that profile a` surface and intersecting that surface with every other surface in the drawing, not boolean intersection, but surface to surface sections.  Lines would have to be projected onto the plane, and if they're perpendicular, those projections will produce points, which TC doesn't do easily. I can think of ways to reveal them, but they don't fit any definition of easy.

Good pre-planning setup will help with this, in the future.  As others suggested, you can initially have put these Objects on their own Layer, and "Select by Layer".  Or assign to these Objects a particular color (which can also be achieved via Color="By Layer"), and "Select by Color".

But if you didn't do that--  In a "busy" model, I would select one of the Objects... keep it selected... go to an Isometric or Dimetric View... keep it selected... "Zoom Selection".  Then Dynamic Examine and/or Zoom in or out as needed.

The 2017 platinum tool has the extract entity tool. You don't need to trace faces anymore.
