<div>Hi Jian,</div>
<div><br>
</div>
You can click in the menu area instead of on the screen, and then type the values in.
<div><br>
</div>
<div>Or, you can use SET GRID to change the grid background such that it contains your point of interest</div>
<div>(Sometimes this is more useful than the above if you have a lot of points.)</div>
<div><br>
</div>
<div>Or, you can build a list of points of the form:</div>
<div><br>
</div>
<div>npoints</div>
<div>x1 y1</div>
<div>x2 y2</div>
<div>...</div>
<div>xnpoints ynpoints</div>
<div><br>
</div>
<div>in a file called "obj.dat" and then click on DEFINE OBJECT, which will set these points to be the</div>
<div>snap points in standard element-input mode.</div>
<div><br>
</div>
<div>Then, use SET GRID to toggle between these points and the other standard background </div>
<div>grid options.</div>
<div><br>

<div dir="ltr">Hi nek,
<div><br>
</div>
<div>I want to generate a 2d pipe mesh using prenek and add 3 elements in first quadrant using [(0, 0), (0.0045, 0), (0.003536, 0.003536), (0, 0.0045)], [(0.0125, 0), (0.00884, 0.00884), (0.003536, 0.003536), (0.0045, 0)], and [(0, 0.0125), (0.00884, 0.00884),
(0.003536, 0.003536), (0, 0.00045)] for 3 elements respectively. But I usually add the element of [(0, 0.0125), (0.00884, 0.00884), (0.003536, 0.003536), (0, 0.00045)] with some difference which would happened on the first point I select. Do you know how could
I click the points very accurately?</div>
