Working with Paper / Model Space

derekjackson — Tue, 19 Oct 2010 15:20:11 GMT

Hi,
I'm trying to generate an object that lets the user choose between Paper or Model space when defining the size of the object output. It's an informative object that gives them a reading on various aspects of the model - I'd like to give them choice to choose its size in Model space for the working model, but also to pick a paper size so that it can be placed on layouts.

Obviously model space works fine - just treat it as any other architectural element.

For the paper space / layout option, I'm taking the output size chosen by the user (sz), and multiplying it by 1/scale, but it doesn't give the correct output.

sz = sz*(1/A_)

Am I using it correctly? Do I need to be using some sort of 'Layout Scale' variable instead?

It's probably really obvious but I'm stumped on this one...

Does this work?

sz = sz*(1000/A_)

Ah - it seems my issue was that I was testing the thing on a layout, which meant it had passed through two different scales - no wonder things were confused.

It now seems to work fine (with sz=sz*A_ in the end)

Thanks anyway!

One more query on this topic.

I'm trying to get Graphical Hotspots to work so that the output can be dragged to a location by the user, and it will maintain a consistent relationship with the main object regardless of paper or model space.

For my readout I currently have a graphical hotspot definition, then an ADD2 to move the origin to the hotpspot, and output the reading:

    hsid=hsid+1
    HOTSPOT2 0,texty,    hsid,textx,1+128
    hsid=hsid+1
    HOTSPOT2 textx,texty,    hsid,textx,2
    hsid=hsid+1
    HOTSPOT2 -1,texty,    hsid,textx,3
    
    hsid=hsid+1
    HOTSPOT2 textx,0,    hsid,texty,1+128
    hsid=hsid+1
    HOTSPOT2 textx,texty,    hsid,texty,2
    hsid=hsid+1
    HOTSPOT2 textx,-1,    hsid,texty,3

    ADD2 textx, texty

For the paper space version, I have:

    textxs = textx*A_
    textys = texty*A_

    hsid=hsid+1
    HOTSPOT2 0,textys,    hsid,textxs,1+128
    hsid=hsid+1
    HOTSPOT2 textxs,textys,    hsid,textxs,2
    hsid=hsid+1
    HOTSPOT2 -1,textys,    hsid,textxs,3
    
    hsid=hsid+1
    HOTSPOT2 textxs,0,    hsid,textys,1+128
    hsid=hsid+1
    HOTSPOT2 textxs,textys,    hsid,textys,2
    hsid=hsid+1
    HOTSPOT2 textxs,-1,    hsid,textys,3

    ADD2 textxs,textys

Although my elements (the object and font size) keep a consistent size regardless of scale, the distance between them keeps fluctuating. Any ideas where my hotspot script is going wrong? All help appreciated!

Thanks,

Derek

I'm not clear exactly what you are trying to do but in my experience it is very difficult (if not impossible) to make dynamic hotspots responsive to both model and paper dimensions. It seems to be pretty much an either/or situation, at least practically speaking.

Derek,
Would you mind sharing with us what kind of an object you are making?

This is straight-forward if you have a clear picture of the whole task. Your aim is for the object to appear on a printed page at a specified size irrespective of scale, e.g. if I say that text is 3mm high, it will always be 3mm high on the printed page.

To achieve this, you need 2 parameters to represent a single measurement - one for the size in paper space (pSize) and the other in model space (mSize).

- If the mSize parameter is not being edited, the Master Script should set mSize = pSize * scale

- If the mSize parameter is stretched, then the Parameter Script should set pSize = mSize / scale

- Always draw the object with mSize, and set the stretchable hotspots against mSize
