hwI3DViewCtrl CircleZoom

Syntax

viewControl_handle CircleZoom

Application

HyperView Tcl Modify

Description

This command allows you to zoom into the model by drawing a window around a particular region. When the command is first executed, it waits for the cursor to move into the graphics area. The left mouse button can then be pressed and moved to draw a window around the region to zoom in on. Moving the mouse outside of the graphics area cancels the operation.

Example

hwi OpenStack;
    set t [::post::GetT];

    catch {
        hwi GetSessionHandle sess$t;
        sess$t GetProjectHandle proj$t;
        proj$t GetPageHandle page$t [proj$t GetActivePage];
        page$t GetWindowHandle win1$t 1;
        page$t GetWindowHandle win2$t 2;
        win1$t GetViewControlHandle vc1$t;
        vc1%t CircleZoom;
    }
    hwi CloseStack;
