thx very much for your tipps! @DLuders yes, I meant the black rubber caterpillar belts. It is better to know that something isn't working at all than trying for hours^^. (Even if it seems strange to me that there is a "fits-onto-nothing-piece" in LDD...^^) I afford to post a pic of the robot. It is a rather easy model which was built as preparatory work for my final work of my time in the er... (maybe) secondary school. (Because the school system is different here in Switzerland, it is a bit difficult to find the correct translation...) With this pic this topic would be closed^^ Image

Dear Community, I just downloaded LDD and wanted to digitalise my Mindstorms robot. My first problem is: How do I get the caterpillar belts (from LDDExtended) on the rims which should match? The second problem which made me almost crazy is: How can I control this middle-size cogwheels more accurately so that the cross axle goes through the middle hole? (with the first cogwheel I got it after 10 minutes of trying...) Finally i wanted to add a second cogwheel which should intertwine with the first but as with the caterpillar belts before LDD mentioned that they don't match. I'm quite sure that this are primitive questions but I haven't found anything in the user manual... In the attachment a picture for Problem 3: The loose cogwheel should get on the free cross axle... Hope someone can help me, sevi008 PS: If there are some (maybe funny...) mistakes in my school english please forgive... -------------------------------------------------------------------------------------------- EDIT I got it with the cogwheels, but I'm still interested in the How-to-use of the caterpillar belts
