Sketcher - Unit Size

I believe the first sketch in a part is roughly the size of a reference plane.

Reference plane sizes are configurable as long as there are no features in the part. Go to Tools->Options->View and change the ref plane size. Make this change in your template part and you should have the desired result.

I too would like a way to set the default empty model size, but your above instructions just take me to the config.pro settings.

I understand the concept of changing the plane size but can not find the ref_plane_size setting in the Options settings

There may be some hidden option in WF or WFII to change the default "world" size, I haven't seen it but it's been requested for some time. As a dirty workaround, you can redefine the start part default datums, making the references to a radius, on the scale you'd like your "world" to be. In WF, there is a 'view' check box, which, when checked, allows you to change the radius. This may be what Geesaman was referring to.

Don't know what you are referring to here, there is no Tools->Options->View in my menu's, is that Wildfire?

Do you mean datum plane? Datum planes are infinite. You can size datum planes, except those made on-the-fly, to visually fit a part, feature, surface, edge, axis, or radius.

The first datum planes in my part appear to visually measure about 508 drawing units in sketcher. Don't know how Proe sets that, but It would be useful to be able to change it.

Tools->Options->View

Interestingly, with only default datums in the model, which are supposed to be infinite, Analysis/Model size shows a finite model size of 881.0254 units.

You CAN change the default datum plane size in Wildfire 1 and 2, and, by extension, the default sketcher scale.

Open your start part, and select each default plane and do EDIT DEFINITION. On the DISPLAY tab, select ADJUST OUTLINE. For the RADIUS value, enter a small value, like 10 or 9 (the default is 500!).

A 10" value gives you a sketcher scale of about 3:1, because of the max/min zoom ratio and because the actual size of the model window is maybe half that of the entire desktop.

Here's the rub: The default planes will scale down to fit features and sketches smaller than the plane size, but WILL NOT scale up to larger features! So if you set the planes to 10" and draw a 50" part, the datum planes will be restricted to no more than 10", and will appear inside the model.

Maybe there's a happy medium, 100" or 80" or something, depending upon the largest part you intend to build.

As first features, default datums can be resized only with radius. When done in start parts, gives a better starting size, except that, in drawing mode, these radiuses show up in detailing. A config option to set the "world" size would be a benefit.

My apologies to everyone. I absentminded answered this question for SolidEdge. I don't know the equivalent procedure in Wildfire.

Dave

First, what a fantasic tweak for Pro-E! Made my day today.

Second, 881 (approx) as the length of corner to corner distance makes sense. This equals a cube of approx 508 on a side.

Got it and made the change - Thanks

Thanks Pete. This works in rel 2001 also, right click the datum plane, click 'Attributes' done, click 'Fit Radius' done, enter a sensible value, enter.

Datum planes ARE infinite.........in theory. In ProE, however, they are pre-set at 508.66". If you don't believe this, open up Wildfire

2, create the defaults, and then rmb>edit definition and see what the values are in the width/height fields.
