Modelspace Zoom Extents

[sigster]

Hi

How can I Zoom Extents in Modelspace after I import data

[sungaoyong]

my code worked successed with

` CadDocument doc = new CadDocument();

VPort vport = doc.VPorts["*Active"];
if (vport != null)
{
vport.Center = new CSMath.XY(40404219.63209335, 3615454.9612060254);
vport.ViewHeight = 1202.0730586005643;
vport.ViewMode = ViewModeType.FrontClippingZ;
vport.UseDefaultLighting = true;
}`

but not success with CadDocument from a file

Hi @sigster

Haven't found a proper way to do it easily, but I think that the trick should be to play with the Entity.GetBoundingBox() and set the VPort *Active values to fit with the entities boxes.

The BoundingBox struct also has methods like Merge(), which you can use to merge different boxes created form entities and have the total boundaries of your drawing.

Hope this helps.
