How to Zoom-in on Small Cells and/or Ultra-Long-Thin Parts

The situation occasionally arises to inspect very small cells and/or ultra-long-skinny parts, such that the regular right-mouse button zoom and/or even the rubber-band zoom features result in either zooming beyond the cells so that they either disappear in you view window, or you can not get the level of detail on them desired.  When this happens, we suggest one of the following strategies.

Turn-off Perspective combined with Region Selection Tool

  1. Try turning-off View > Perspective
  2. Turn-on the Region (selection) tool visibility (click icon)
  3. Then apply repeated combinations of
    • Use the middle-mouse button to translate the object under the Region Selecton tool, and then
    • Select the zoom (magnifying glass) option on the Region selection tool to execute a zoom.

Adjust Transformation Editor (Z-Clip) > Minimum Z value combined with Region Selection Tool

  1. Select Graphic window transforms > Transformation editor... to open the Transformation Editor dialog
    • From this dialog select Editor function > Z-clip to set this dialog to the Transformation Editor (Z-Clip) dialog
    • Change the Minimum Z value from 1.0000e-04 to 1.0000e-06, and dismiss this dialog
  2. Next toggle-on the Region (selection) tool visibility and apply repeat combinations of
    • Right-(mouse button)-click > Set center of transform on the area in question,
    • Use the middle-mouse button to translate the object under the Region Selecton tool, and then
    • Select the zoom (magnifying glass) option on the Region selection tool to execute a zoom.

Offset Geometry Visually by Creating a Displacement Vector

For ultra-long-thin parts you may have to resort to scaling the model visibility by creating a displacement vector as follows:

  1. Make a server-side coordinate vector by selecting the part(s) and using the calculator. For instance, if your part is planar defined ultra-long in the x-direction and ultra-thin in the y-direction you would create the following sequence of variables:
    • crdx = Coordinates[X]
    • crdy = Coordinates[Y}
    • crdz = Coordinates[Z]
    • MakeVect = MakeVect(plist,crdx,crdy,
  2. Now with the part(s) selected, apply this MakeVect as a Displacements variable along with a suitable displacement value (might need to scale to 1000 or more depending on your coordinate extent).  Also, note that this type of displacement is a visual displacement and does not scale the geometry of the parts on the server computationally.
  3. Then use the right-click > Set center of transformation on the part to center transformations, and finally
  4. Use either Right-mouse button zoom, Rubber-band zoom, or a combination of previous techniques to zoom-in on your part cell.

Transformation Editor (Global transform) > Scale 

Sometimes the Transformation Editor (Global transform) > Scale Transform action option will work in these situations. If not, one of the above options are your best choice.
