Zooming and panning in drawings

The zooming commands in the context menu in drawings allow you to focus on a particular area, or pull out for a wider view. You can also use the mouse, keyboard shortcuts or Quick Launch. You can also pan (move) the drawings.

Tip: Try the advanced option XS_USE_SMART_PAN: To activate optimized zooming and panning in drawings, set this advanced option to TRUE. When the smart pan is enabled while you pan or zoom a heavy drawing with lots of graphics, the whole screen is not drawn, empty space is left on the edges, and zooming and panning is faster. The default setting is FALSE, because using the optimization sometimes results in an unwanted checkerboard effect.
Note:

The point at which the level of detail is reduced in drawings was set earlier starting from the Tekla Structures version 2020. This means that zooming out in drawings drops details earlier than before. As a result, overall zooming and panning is smoother, while some drawing content is simplified and some is left out when zoomed out to certain extent. The effect is easy to notice in large drawings with a high amount of content.

The change in the level of detail affects:

  • Hidden lines, which are not drawn

  • Very short lines, which are not drawn

  • Hatches, which are drawn as a cloud of points

  • Text, which is replaced by a line
