Editing the MVO settings for stairs

I had discussed this issue last week as a side request talking about "wishes" and was not about wishes. So, today I would like to ask the question in earnest in hoping that someone can tell me, How does the user (me) modify/edit the MVO settings, especially for stairs? Obviously all the MVO data was created when the stair tool was createdl so there must be some way to open up the stair tool and get access to the MVO data. Any and all assistance appreciated.

Hello Kevin:  I was able to find the base macros as you indicated using the library manager but it doesn't allow me to open the file. Based on your picture it doesn't look like the window is in the library manger. I tried to get access using the object tool but that isn't possible. Can you provide more information on how to actually open the "Getstairglobals.gsm" file?




? Not sure I understand your logic. The values in the MVO settings are an independent database of values. The stair tool reads these values and adjusts the appearance of the stairs so you have a consistent appearance across all stairs in the current view according to the MVO you assign in your View Settings.


Any potential overrides of the MVO settings will be displayed in the stair settings.


Any other adjustment would require editing the stair object, which is rarely a simple task for a GS object and probably extremely complex for the stair tool.

My logic is that I want to turn OFF the headroom indicator or change its pen to transparent so that it does not show in 3D. I just submitted an inquiry that needed a 3D picture of the stairs with railings but the headroom indicator makes thing difficult to see. My understanding is that the control for the headroom and pen colour are in the MVO (stair database) and since the stair option for the headroom indication cannot be turned off in the attributes section for stairs the only solution would be to open the database for stairs and modify it to turn the headroom off. I am surprised that that option is not available in the attributes section. I'm sure it would be simple for someone at Graphisoft to turn it off but that would require and update that wouldn't be practical for just one item. Therefore I was looking for a way that would allow me to  make the necessary changes. Does that help?


Neither of the Macros indicated above refer to the headroom. The Macros can only transfer requested parameter values, so they won't help you.


The staircase is a hardcoded element so it can't be viewed or edited. I have a feeling this also applies to the headroom surfaces & colour.


The best you can do, as mentioned in the other thread, is to turn the headroom on/off in the MVO to suit your view. This also works in 3D.


I agree with you that the ability to change the headroom colour / transparency would be a big help, as would changing the linetype, but we seem to be stuck with manual graphics in sections and orange blobs in 3D for now.
