Resolving an Intersection Error

The eMachineShop CAD requires all lines to be closed shapes and non-intersecting (not overlapping), otherwise you will receive an error. To resolve an intersection error there are two methods:

To create a valid 2D shape:

  1. While holding the Ctrl key (to multi-select) click on the intersecting lines. 
  2. On the toolbar click the Intersect button.
  3. Delete one or more line segments to create a single closed shape by clicking on the segment(s) and pressing the Delete button. 

To create a valid 3D shape between two lines:

  1. On the numeric bar set the nudge value to 0.1″.
  2. Think of the two lines as line A and line B.
  3. While holding the Ctrl key (to multi-select) click on lines A and B. 
  4. Using the keyboard arrow keys nudge the lines to a blank area.
  5. Choose Line | Intersect.
  6. Click the mouse in a blank area.
  7. If any of the line segments cross over an area where you plan to have a hole or cutout going fully thru your part, delete only those lines. 
  8. Multi-select the nudged lines by dragging a selection rectangle around the lines.
  9. Choose Line | Repeat to create a copy.
  10. Nudge the copy away from the original and on the keyboard press the “=” key. 
  11. In the original version of the nudged lines: delete one or more line segments to leave a closed shape comprised of segments from A and B (for example you might delete all the interior lines leaving the outermost lines); group the lines of the resulting shape together by multi-selecting them and choosing Line | Group; nudge the shape back to its original position in the design; and set Z on the numeric bar (if you don’t know what value to use choose 0.1 for now).
  12. In the other nudged copy: delete some line segments to leave a different closed shape (this shape can be comprised of segments from just A, just B or both); group the lines of the resulting shape together by selecting them and choosing Line | Group; nudge the shape back to its original position in the design; and set Z (if you don’t know what value to use choose 0.1 for now).
  13. Choose View | 3D
  14. If the result is not as desired you probably did not set Z properly (you might need to change the value or change to a negative value or Air Inside); or you did not make the proper closed shapes. If so, undo the above changes and revise accordingly.
