Using magnification in ortho view

Hi. I have successfully used view distance ranges in Perspective View to make visual objects appear or disappear to show the level of detail that I desire.

I have not been able to figure out how to do it in Ortho mode though, with the magnification option. Can you please give me some directions?

Software Version:

FlexSim 18.0.3

Are you changing these values on the OnDraw" Trigger? the notes for this are given when you click the code editor when using "Hide shape and contents at a distance" they read:

A higher "View magnification" value decreases the distance at which the shape becomes hidden in the Orthographic View"

A lower "View distance" value decreases the distance at which the shape becomes hidden in the Perspective View

@Joshua S I am achieving this (watch attached video): https://youtu.be/TNaf5nMayy8

By usiing this code:

if ( (getnodenum(viewmagnification(view)) > viewmag ||
	getnodenum(viewprojectiontype(view)) == 0) &&
    (distfromviewpoint(current, view) < 8490 && distfromviewpoint(current, view) > 6500)) {
	switch_hidecontents(current,0); // show the contents
	if (getobjectshapeindex(current)==0) // if the shape is hidden
		setobjectshapeindex(current,getshapeindex(gets(shape(current)))); // show the shape
	for (int r=1; r<=content(drawsurrogate(current)); r++) {
		treenode obj = rank(drawsurrogate(current),r);
		switch_hidecontents(obj,0); // show the contents
		if (getobjectshapeindex(obj)==0) // if the shape is hidden
			setobjectshapeindex(obj,getshapeindex(gets(shape(obj)))); // show the shape
	}
	return 0; // default draw code
} else {
	switch_hidecontents(current,1); // hide the contents
	setobjectshapeindex(current,0); // hide the shape
	for (int r=1; r<=content(drawsurrogate(current)); r++) {
		treenode obj = rank(drawsurrogate(current),r);
		switch_hidecontents(obj,1); // hide the contents
		setobjectshapeindex(obj,0); // hide the shape
	}<br>

I understand how it works in perspective mode but not in ortho. Is it the same principle?

It works in the same manner. I edited the code:

double ViewFarClip= 12;
double ViewNearClip=70;
print(getnodenum(viewmagnification(view)));
if (getnodenum(viewmagnification(view))> ViewNearClip && getnodenum(viewmagnification(view))<ViewFarClip)  {
	//Draw Cities
} else {
	// Don't Draw Cities
}

this does what your perspective zoom does.

@Joshua S Printing the magnification really helped, as it works differently in ortho mode. As you get farther away the number gets smaller. Now it's working really good and it looks perfect.
