Support Questions & Answers
Q) I like the old array dialog box back, what do I need to do to see it again?

A) To use the dialog box, you need to type it on command line: ARRAYCLASSIC


Q) I recently upgraded from OSX 10.7 to 10.8 running Parallels 8. After performing this upgrade I lost functionality of my center wheel to click, pan, and release pan. I was also not able to click on the widows button as well. It would stay in pan right click, esc, would not remedy the problem. I was able to click on the command line and this would release the pan then click and drag in the drawing press esc and I had control once again. A) After deciding there was a driver issue with Parallels 8 I performed the following steps.
1. Download updated driver software for my logitech mouse.
2. clicked on the Devices menu
3. clicked on USB
4. clicked on my mouse clicked yes
5. waited for drivers to load
6. tested mouse functionality
7. press control and Option to release mouse from windows
8. clicked on the Devices menu
9. clicked on USB
10. unchecked my mouse
11. hopefully this works for you


Q) How can I change the orientation of the crosshairs to select blocks on an angle?
i.e. my seating is rotated at a 27d angle and I want to follow the angle of the chairs do select them in rows to change the Z axis elevation.

A) Right mouse click over any icon… look for and click on UCS II. Whey that pallet opens, click on the first icon on the left... Click and Click will set the cursor.
Defines a new UCS using one, two, or three points. If you specify a single point, the origin of the current UCS shifts without changing the orientation of the X, Y, and Z axes. Specify point on X-axis or <Accept>: Specify a second point or press Enter to limit input to a single point
If you specify a second point, the UCS rotates around the previously specified origin point such that the positive X axis of the UCS passes through the point. Specify point on XY plane or <Accept>: Specify a third point or press Enter to limit input to two points
If you specify a third point, the UCS rotates around the X axis such that the positive Y half of the XY plane of the UCS contains the point. The three points specify an origin point, a point on the positive X axis, and a point on the positive XY plane. For more on this… F1 Help and type UCS into the Index


Q) How can set the height when using the Polysolid tool? I trace the wall and then have to go back and grab the 2 grips and stretch them to the desired height. Is there a better way?

A) Looking at the command line... you will see Height/Width/Justify use these to set the Height and Width of the wall you are going to draw. If a light is focused 1' away or 10' away does it change the distance the light will shine when rendered or does the beam go infinite in that focused direction? The cone will tell you the candle power. Just place you cursor by it and you will get a tool tip.


Q) If I zoom in too far on the 'paper' in a plotting tab and then double-click in the viewport on the 'paper' to navigative my angle for the plot I don't have the ability to double click outside of that viewport to zoom out and see the whole piece of 'paper'. How do I correct this mistake of zooming in too far from the start?

A) Looking at the bottom, you will see a button called Model. By clicking on this button will change it back to the paper space and you will be able to zoom in and out. Or Look at the bottom; you will see a button called Model or Paper... try clicking on it.
